- ### 🤕 Fixes
- **Update binary-install to v0.4.1 - [drager], [pull/1407]**
Release v0.4.0 of binary-install introduced a regression that caused failures on some platforms. This release fixes that regression.
[pull/1407]: https://github.com/rustwasm/wasm-pack/pull/1407
[drager]: https://github.com/drager
- ** Allow npm binary upgrades - [net], [pull/1439]**
Fixes an issue where upgrading `wasm-pack` via NPM would not update the underlying binary.
Previously, the binary was stored in the `binary-install` package's directory without versioning, causing version upgrades to silently fail as the old binary continued to be used.
The binary is now stored in `node_modules/wasm-pack/binary/`, ensuring proper version updates when upgrading the package.
**Before:** Upgrading from `0.12.1` to `0.13.0` would continue using the `0.12.1` binary
**After:** Each `wasm-pack` version manages its own binary, enabling proper version upgrades

- ### 🤕 Fixes
- **Fix passing relative paths to cargo - [dfaust], [issue/704], [issue/1156], [issue/1252], [pull/1331]**
When building a crate located in a sub-directory, relative paths, passed as extra options to cargo (like `--target-dir`), are now handled correctly.

- **Rewrite wasm_target to use target-libdir - [daidoji], [issue/1342], [pull/1343]**
Rewritten wasm_target to use target libdir from the rustc tool rather than looking through sysroot. This is to accomodate non-rustup installations.

- **Declare ES module in package.json - [gthb], [issue/1039], [pull/1061]**
In bundler mode, generate package.json with "type": "module" and use the "main" attribute instead of the "module" attribute.
This change makes the built ES module palatable to Node.js (when run with --experimental-vm-modules --experimental-wasm-modules),
while it remains also palatable to webpack as illustrated in webpack/webpack#14313
(where the pkg subfolder is generated with wasm-pack built with this change).
This resolves the headache of using a wasm-pack-built package in a library that one needs to both run directly in Node and include in a webpack build.

A recent change ensured that the pkg directory was removed as the first step of attempting to create it.
Unfortunately, this caused a problem for webpack when watching the pkg directory.
Webpack was unable to recover its watching and so any watch server must be restarted,
which is a blocker when using it. This PR and release fixes this.

- **Pass through extra options when building tests - [azriel91], [issue/698] [pull/851]**
`wasm-pack test` accepts extra options to pass through to `cargo` when running tests.
Under the hood, this runs `cargo build` before `cargo test`, and the additional options were only passed through to the `test` command. This meant that crates that enabled native features by default could not be built using `wasm-pack`, as it would attempt to build tests for the `wasm32-unknown-unknown` target with the native features enabled.
This PR passes through the extra options to `cargo` when building the tests as well.

Previously, wasm-pack was hardcoded to install and attempt to execute wasm-opt on every build

This PR updates the binaryen version to 90, which should fix the issues folks were having.

- ### ✨ Features
- **Adding in `--quiet` and `--log-level` flags to control the console output - [Pauan], [pull/694]**
The `--verbose` flag has long existed as a way to get more console output, but now there are two flags to get *less* console output:
* `--quiet` will silence *all* stdout, so only errors will be displayed.
* `--log-level` can be used to silence `[INFO]` or `[WARN]` output from wasm-pack.
You can cause it to display even *more* information by using `--verbose`, or you can silence *all* stdout by using `--quiet`.
You can also use `--log-level` to have fine-grained control over wasm-pack's log output:
* `--log-level info` is the default, it causes all messages to be logged.
* `--log-level warn` causes warnings and errors to be displayed, but not info.
* `--log-level error` causes only errors to be displayed.
These flags are global flags, so they can be used with every command, and they must come *before* the command:
```sh
wasm-pack --log-level error build
wasm-pack --quiet build
```

One of the first steps in getting started with `wasm-pack` is to `cargo install cargo-generate` to bootstrap some project templates. This can take a while and is an extra burden on users just getting started with `wasm-pack`. `wasm-pack new` uses `cargo-generate` to bootstrap new projects, removing the need to install the tool on your own.

- **Only use exactly v0.24.0 geckodriver on Windows - [ashleygwilliams], [issue/770] [pull/774]**
`wasm-pack test` is a great way to test your web Wasm modules- and it very nicely sets up and configures
the necessary browser engine drivers to do so!
For the v0.25.0 release of geckodriver, the team switched their build environment- which introduced a new
surprise runtime dependency, Visual C++ redistributable package, to their windows binaries. You can read
more about the issue here, [mozilla/geckodriver/issue/1617].
Becuase the introduction of this runtime dependency is considered a bug, and should be eventually fixed,
the team decided that the least invasive solution would be to hold geckodriver binaries, on Windows, at
v0.24.0, and to disable the auto-update logic, until the bug is fixed.

- **Check for "rustup" rather than ".rustup" when checking for wasm32 - [drager], [issue/613][pull/616]**
When we introduced support for non-rustup setups we did a check if the user was
using rustup or not. However, this check was too constrained and only covered
the most common cases, but it did not work for Docker setups.
This PR addresses that and it now covers Docker setups as well!
When doing this fix we also found two other small issues which this PR also addresses.
The first is that we did not print the helpful error message when the wasm32 target
was not found and the other one was that it linked to the wrong section of the documentation.

- **Give user's ability to customize generated filenames with `--out-name` flag - [ibaryshnikov], [issue/596] [pull/599]**
When running `wasm-pack build`, several files are generated. These files
are named based on the name of the crate, as per your `Cargo.toml` file.
Sometimes- that's not the name you'd like your files to have!
You can now specify a custom name for the generated files using a new
flag, `--out-name`. Given a project called `dom`, here's a comparison of
the default and custom generated filenames:
```
wasm-pack build
# will produce files
# dom.d.ts dom.js dom_bg.d.ts dom_bg.wasm package.json README.md
wasm-pack build --out-name index

- **Fix panics in `build mode --no-install` - [alexcrichton], [pull/598]**
This commit fixes the `wasm-pack build --mode no-install` command from
unconditionally panicking as well as `--mode force`. These steps were
calling an `unwrap()` on an internal `Option<T>` which was supposed to
be set during `step_install_wasm_bindgen`, but that step wasn't run in
these modes. The mode configuration of steps has been refactored
slightly to ensure that more steps are shared between these modes to
reduce duplication.

- **Print unexpected panics to standard error - [drager], [issue/562] [pull/601]**
Unexpected panics are unfortunate but they're currently covered up and written

especially at a glance, as CI builders are likely not uploading those files.

`human_panic` handle panics, just like before.

We've updated the error message to include more information, and we've added

installing the target on your specific rust setup- including the fact that
it may *not* be possible to add the target to some setups.

- **Fix broken links in docs and update for template changes - [drager], [ashleygwilliams], [issue/609] [pull/612] [pull/614]**
Recently, some improvements were made to the [`wasmpack-template`]. Additionally,
there were some broken links in the documentation. We've updated the docs for the
new template and fixed the broken links!

- ### 🛠️ Maintenance
- **Move `binary-install` to its own repo - [drager], [issue/500] [pull/600]**
`binary-install` is a crate that holds the abstractions for how `wasm-pack` downloads
and caches pre-built binaries for the tools it wraps. It was originally part of the
`wasm-pack` code, then moved into a workspace as an independent crate. Now that we
believe it's stable, we've moved it into its own [repo](https://github.com/rustwasm/binary-install)!

## 🌤️ 0.7.0
- ### ✨ Features
- **Non `rustup` environment support - [drager], [pull/552]**
Before now, `wasm-pack` had a hard requirement that `rustup` had to be in the PATH. While most Rust users use
`rustup` there are variety reasons to have an environment that doesn't use `rustup`. With this PR, we'll now
support folks who are using a non-`rustup` environment!

- **Improved CLI Output - [alexcrichton], [pull/547]**
It's hard to decide if this is a fix or a feature, but let's keep it positive! This PR moves `wasm-pack`'s CLI
output strategy closer to the desired standard we have for 1.0. This is important as it fixes many small bugs
that are distributed across a diveristy of terminals and difficult to test for locally.
This strategy was first introduced as a mini RFC in [issue/298], and then was discussed in a session at the Rust
All Hands ([notes](https://gist.github.com/fitzgen/23a62ebbd67574b9f6f72e5ac8eaeb67#file-road-to-wasm-pack-1-0-md)).
You'll notice that the spinner is gone- we eventually want to have one, but we'd like one that doesn't cause bugs!
If you have feedback about terminal support or an output bug, please [file an issue]! We want to hear from you!
Check out the new output in the `README` demo- or update your `wasm-pack` and take it for a spin!

- **Add support for `--target web` - [alexcrichton], [pull/567]**
Recently, `wasm-bindgen` add a new target- `web`. This new target is similar to the `no-modules` target, in that
it is designed to generate code that should be loaded directly in a browser, without the need of a bundler. As
opposed to the `no-modules` target, which produces an IIFE (Immediately Invoked Function Expression), this target
produces code that is an ES6 module.
You can use this target by running:
```
wasm-pack build --target web
```
Learn more about how to use this target by [checking out the docs!](https://rustwasm.github.io/wasm-pack/book/commands/build.html#target)

- **Support passing arbitrary arguments to `cargo test` via `wasm-pack test` - [chinedufn], [issue/525] [pull/530]**
`wasm-pack test` is an awesome command that wraps `cargo test` in a way that helps provide you some nice out of the
box configuration and setup. However, you may find yourself wanting to leverage the full funcationality of `cargo test`
by passing arguments that haven't been re-exported by the `wasm-pack test` interface.
For example, if you have a large test suite, it can be nice to simply run one test, or a subset of your tests.
`cargo test` supports this, however up until now, the `wasm-pack test` interface did not!
`wasm-pack test` now accepts passing and arbitrary set of arguments that it will forward along to its `cargo test` call
by allowing users to use `--` after any `wasm-pack test` arguments, followed by the set of arguments you'd like to pass
to `cargo test`.
For example:
```
# Anything after `--` gets passed to the `cargo test`
wasm-pack test --firefox --headless -- --package my-workspace-crate my_test_name --color=always
```
This will just run the `my_test_name` test and will output using color!

- **Support `homepage` field of `Cargo.toml` and `package.json` - [rhysd], [pull/531]**
Both `Cargo.toml` and `package.json` support a `homepage` field that allow you to specify a website for
your project. We didn't support it previously (purely an accidental omission) - but now we do!
[pull/531]: https://github.com/rustwasm/wasm-pack/pull/531
- **Support `license-file` field in `Cargo.toml` - [rhysd], [pull/527]**
Sometimes, you want to provide a custom license, or specific license file that doesn't map to SPDX standard
licenses. In Rust/Cargo, you accomplish this by omitting the `license` field and including a `license-file`
field instead. You can read more about this in the [`cargo` manifest documentation].
In an npm package, this translates to `"license": "SEE LICENSE IN <filename>"` in your `package.json`. You can
read more about this in the [npm `package.json` documentation].
We previously only supported using SPDX standard licenses, by only supporting the `"license"` key in your
`Cargo.toml`- but now we'll allow you to leverage the `license-file` key as well, and will translate it
correctly into your `package.json`!

- ### 🤕 Fixes
- **`wasm-pack-init (1).exe` should work - [ashleygwilliams], [issue/518] [pull/550]**
Several users noted that when downloading a new version of `wasm-pack` their browser named the executable
file `wasm-pack-init (1).exe`. When named this way, the file didn't show the init instructions on execution.
This happened because the installation logic was requiring an exact match on filename. We've loosened that
restriction so that the filename must *start* with `wasm-pack-init` and will still execute files with these
additional, extraneous charaters in the filename. Thanks so much to [Mblkolo] and [danwilhelm] for filing the
issue and the excellent discussion!

- **Fix chromedriver error and message on Windows for `wasm-pack test` - [jscheffner], [issue/535] [pull/537]**
When running `wasm-pack test` on a 64-bit Windows machine, users would receive an error:
`geckodriver binaries are unavailable for this target`. This error message had two issues- firstly, it accidentally
said "geckodriver" instead of "chromedriver", secondly, it threw an error instead of using the available 32-bit
chromedriver distribution. Chromedriver does not do a specific disribution for Windows 64-bit!
We've fixed the error message and have also ensured that 64-bit Windows users won't encounter an error, and will
appropriately fallback to the 32-bit Windows chromedriver.

- **Correct look up location for `wasm-bindgen` when it's installed via `cargo install` - [fitzgen], [pull/504]**
Sometimes, when a `wasm-bindgen` binary is not available, or if `wasm-pack` is being run on an architecture that
`wasm-bindgen` doesn't produce binaries for, instead of downloading a pre-built binary, `wasm-pack` will install
`wasm-bindgen` using `cargo install`. This is a great and flexible back up!
However, due to the last release's recent refactor to use a global cache, we overlooked the `cargo install` case
and did not look for `wasm-bindgen` in the appropriate location. As a result, this led to a bug where `wasm-pack`
would panic.
We've fixed the lookup for the `cargo install`'d `wasm-bindgen` by moving the `cargo-install`'d version to global
cache location for `wasm-pack` once it's successfully built. We also eliminated the panic in favor of
propagating an error. Thanks for your bug reports and sorry about the mistake!

- **Fix `clippy` warnings - [mstallmo], [issue/477] [pull/478]**
[`clippy`] is an awesome utilty that helps lint your Rust code for common optimizations and idioms. at the
beginning of `wasm-pack` development, `clippy` had not yet stablized, but it has since 1.0'd and it was
high time we leveraged it in `wasm-pack`. We still aren't *completely* fixed, but we're working on it, and
we've already dervived a ton of value from the tool!

- **Port tests to use `assert-cmd` - [fitzgen], [pull/522]**
[`assert_cmd`] is a great utility for testing CLI applications that is supported by the [CLI WG]. `wasm-pack`

In the last release, we separated some of our binary install logic into a new crate, `binary-install`.
However, that's about all we did... move the logic! In an effort to move the crate into true open source

Our tests use fixtures that reference `wasm-bindgen` often, but the versions were not consistent or up to
date. As a result, the test suite leverage many version of `wasm-bindgen` which meant that they took a while

- ### 📖 Documentation
- **Flag gh-pages docs as unpublished - [alexcrichton] [pull/565]**
Recently, [DebugSteven] made a PR to merge all the documentation for the rustwasm toolchain into a
[single location]. This is going to make discovering and using tools from the entire organization easier
for new and seasoned folks alike. This also has the feature of displaying documentation that is related
to the current published version of each tool- unlike before, where the only accessible documentation was
for the tools at current master (which may or may not be currently published!)
If you like reading the current master's documentation- fear not, each tool will still publish the
documentation generated from the master branch on their individual `gh-pages`
([See `wasm-pack's` master docs here]). To avoid confusion, we've added a flash message that let's you know
which documentation you are reading- and provides a link to documentation of the published version- just
in case that's what you're looking for!

- **Add new QuickStart guide for "Hybrid Applications with Webpack" - [DebugSteven] [pull/536]**
Since `wasm-pack` was first published, we've focused on a workflow where a user writes a library and then
publishes it to npm, where anyone can use it like any npm package in their JavaScript or Node.js application.
Shortly after `wasm-pack` appeared, some RustWASM teammates created a template for a similar workflow- building
a RustWASM package *alongside* an application. They did this by leveraging Webpack plugins, and it's a really
lovely user experience!
[This template] hasn't gotten as much attention because we've lacked a quickstart guide for folks to discover
and follow- now we've got one!

`wee_alloc` is a useful utility that deserved more attention and explanation than our previous docs addressed.

However, for folks who don't use the template, `wee_alloc` is something important to know about- so now we have
given it its own section!

- **Update prerequisite documentation - [alexcrichton], [pull/569]**
Many folks are using `wasm-pack` without publishing to npm- as a result, we've updated the documentation to
clearly indicate that npm is an optional requirement, only required for specific targets and workflows.
Additionally, since the 2018 Edition landed, `nightly` Rust is no longer a requirement. We've removed those
instructions and have consolidated the documentation so it is shorter and more efficient at getting you
started!

Ever wonder how you're *actually* supposed to refer to WebAssembly in short-form? WASM? wasm? For the pedants

## 🌅 0.6.0
- ### ✨ Features
- **Add three build profiles and infrastructure for their toml config - [fitzgen], [issue/153] [issue/160] [pull/440]**
When originally conceived, `wasm-pack` was exclusively a packaging and publishing tool, which naively assumed
that the crate author would simply run `wasm-pack` when they were ready to publish a wasm package. As a result,
`wasm-pack` always ran `cargo build` in `--release` mode. Since then, `wasm-pack` has grown into an integrated build
tool used at all stages of development, from idea conception to publishing, and as such has developed new needs.
In previous releases, we've supported a flag called `--debug` which will run `cargo build` in `dev` mode, which
trades faster compilation speed for a lack of optimizations. We've renamed this flag to `--dev` to match `cargo`
and added an additional flag, representing a third, intermediary, build profile, called `--profiling` which
is useful for investigating performance issues. You can see all three flags and their uses in the table below:
| Profile | Debug Assertions | Debug Info | Optimizations | Notes |
|---------------|------------------|------------|---------------|---------------------------------------|
| `--dev` | Yes | Yes | No | Useful for development and debugging. |
| `--profiling` | No | Yes | Yes | Useful when profiling and investigating performance issues. |
| `--release` | No | No | Yes | Useful for shipping to production. |
The meaning of these flags will evolve as the platform grows, and always be tied to the behavior of these flags
in `cargo`. You can learn more about these in the [`cargo profile` documentation].
This PR also introduces a way to configure `wasm-pack` in your `Cargo.toml` file that we intend to use much more
in the future. As a largely convention-based tool, `wasm-pack` will never require that you configure it manually,
however, as our community and their projects mature alongside the tool, it became clear that allowing folks the
ability to drop down and configure things was something we needed to do to meet their needs.
Currently, you can only configure things related to the above-mentioned build profiles. To learn more,
[check out the documentation][profile-config-docs]. It leverages the `package.metadata.wasm-pack` key in your
`Cargo.toml`, and looks like this:
```toml
# Cargo.toml
[package.metadata.wasm-pack.profile.dev.wasm-bindgen]
# Should we enable wasm-bindgen's debug assertions in its generated JS glue?
debug-js-glue = true
# Should wasm-bindgen demangle the symbols in the "name" custom section?
demangle-name-section = true
# Should we emit the DWARF debug info custom sections?
dwarf-debug-info = false
```
As always- there are defaults for you to use, but if you love to configure (or have a project that requires it),
get excited, as your options have grown now and will continue to!

- **DEPRECATION: Rename `--debug` to `--dev` to match `cargo` - [fitzgen], [pull/439]**

- **Add an option to pass an arbitrary set of arguments to `cargo build` - [torkve], [issue/455] [pull/461]**
As an integrated build tool, `wasm-pack` orchestrates many secondary command line tools to build your package
in a single command. Notably, one of these tools is `cargo`. `cargo` has a wide array of features and flags, and
we couldn't reasonably expect to implement them all as first class features of `wasm-pack`. As a result, we've
created the option to allow users to pass an arbitrary number of additional flags to `wasm-pack` by appending them
to the `wasm-pack build` command, after passing `--`. For example:
```
wasm-pack build examples/js-hello-world --mode no-install -- -Z offline
```
In the above example, the flag `-Z offline` will be passed to `cargo build`. This feature is documented
[here][cargo opts docs].

- **Pre-build before wasm-pack publish - [csmoe], [issue/438] [pull/444]**
Previously, if you ran `wasm-pack publish` before you had successfully run `wasm-pack build`,
you'd receive an error that a package could not be found- because there would be no `pkg` or
out-directory containing a `package.json`.
In this situation, you would hope that `wasm-pack` would build your package for you when you
ran `wasm-pack publish`. This is slightly complicated by the fact that not everyone wants to
build their package to the default target or to a directory named `pkg`.
To solve this, running `wasm-pack publish` before a successful build will give you an interactive
prompt to build your package- allowing you to specify your out directory as well as the target you'd
like to build to. Check it out in the gif below:
![pre-build publish workflow](https://user-images.githubusercontent.com/35686186/50500909-5984fe80-0a8f-11e9-9de6-43d1423b2969.gif)

- **Generate self-.gitignore as part of pkg folder - [RReverser], [pull/453]**
Since `wasm-pack` was first published, the `pkg` directory was intended to be treated as a
build artifact, and as such should never be published to version control. This was
never enforced by any assets generated by `wasm-pack`, however.
Now, when building your package, `wasm-pack` will also generate a `.gitignore` file so that the
`pkg`, or out-directory, will be ignored.
If you use another version control tool, you'll need to still create or edit your own ignore file-
pull requests to support other version control tools are welcome!
If you require editing of the generated `package.json` or add additonal assets to your package
before publishing, you'll want to remove the `.gitignore` file and commit to version control. We
intend to have a solution that makes this workflow significantly easier in upcoming releases!

- **Support cargo workspaces - [fitzgen], [issue/252] [issue/305] [pull/430]**
Workspaces are a well-liked and used feature of cargo that allow you to build multiple crates
in a single cargo project. Because of how `wasm-pack` handled paths for `target` and out-directories,
we did not support cargo workspaces out of the box. Now they should work well and the feature is
well guarded by tests!

- **Use a global cache for all downloaded binaries - [alexcrichton], [pull/426]**
`wasm-pack` is an integrated build tool that orchestrates several other command line tools to build
your wasm project for you. How `wasm-pack` does this has evolved significantly since it's early versions.
In the last version, a `bin` directory was created to house the tool binaries that `wasm-pack` needed to
build our project, but this had several limitations. Firstly, it created a `bin` directory in your project's
root, which could be confusing. Secondly, it meant that sharing these tools across multiple projects was
not possible. We did this because it gaves us the fine-grained control over the version of these tools that
you used.
Now, `wasm-pack` will not generate a `bin` directory, but rather will use a global cache. We retain the
fine-grained control over the versions of these tools that are used, but allow multiple projects that use
the same tools at the same versions to share the already installed asset. Your global cache will generally
be in your user's home directory- we use the [`dirs` crate] to determine where to place this global cache.
This is not currently customizable but is something we intend to look into doing!
This feature ensures that `wasm-pack` users are downloading a minimal number of binaries from the network,
which, for `wasm-pack` users with multiple projects, should speed up build times.

- **Fix `pack`, `login`, and `publish` for Windows users - [danwilhelm], [issue/277] [pull/489]**
Rust's behavior for spawning processes on some Windows targets introduced an interesting case where
Rust would fail unless the command was explicitly spawned with a prepended `cmd /c`. This failure
of `wasm-pack` was well noticed by our community - and thanks to the efforts of `danwilhelm` is now
fixed! You can read more on the background of this issue in [rust-lang/rust issue/44542].

- **Validate `--target` argument - [csmoe], [issue/483] [pull/484]**
For a few releases now, `wasm-pack` has supported allowing users to specifying the target module system
they'd like their package built for- `browser`, `nodejs`, and `no-modules`. We did not however, validate
this input, and so if a user made even a slight mistake, e.g. `node`, `wasm-pack` would not catch the
error and would build your project using the default, `browser`. This is of course, surprising, and
unpleasant behavior and so now we'll error out with a message containing the supported target names.

- **Eliminate unecessary escaping in build success terminal output - [huangjj27], [issue/390] [pull/396]**
Previously, on some systems, a successful `wasm-pack build` would print a unfortunate looking string:
```
| :-) Your wasm pkg is ready to publish at "\\\\?\\C:\\Users\\Ferris\\tmp\\wasm-bug\\pkg".
```
We've updated this to make sure the path to your project is well-formed, and most importantly,
human-readable.

- **Copy license file(s) to out directory - [mstallmo], [issue/407] [pull/411]**
Since `wasm-pack` was first published, we've copied over your `Cargo.toml` license definition over to
your `package.json`. However, we overlooked copying the actual `LICENSE` files over! Now we do!

- **Don't require cdylib crate-type for testing - [alexcrichton], [pull/442]**
`wasm-pack` was unecssarily checking `Cargo.toml` for the `cdylib` crate type during calls to `wasm-pack test`.
The `cdylib` output isn't necessary for the `wasm-pack test` stage because `wasm-bindgen` isn't being run over
a wasm file during testing. This check is now removed!
[pull/442]: https://github.com/rustwasm/wasm-pack/pull/442
- **Fix wasm-bindgen if lib is renamed via `lib.name` - [alexcrichton], [issue/339] [pull/435]**
In some circumstances, a library author may wish to specify a `name` in the `[package]` portion of their
`Cargo.toml`, as well as a different `name` in the `[lib]` portion, e.g.:
```toml
[package]
name = "hello-wasm"
[lib]
name = "wasm-lib"
```
This would cause the `wasm-bindgen` build stage of `wasm-pack` to error out because `wasm-pack` would attempt
to run `wasm-bindgen-cli` on a path using the `[package]` name, which wouldn't exist (because it would be using
the `[lib]` name). Now it works- thanks to more usage of [`cargo_metadata`] in `wasm-pack` internals!

- **Print standard error only once for failing commands - [fitzgen], [issue/422] [pull/424]**
Previously, `wasm-pack` may have printed `stderr` twice in some circumstances. This was both confusing and not
a pleasant experience, so now we've ensued that `wasm-pack` prints `stderr` exactly once! (It's hard enough to have
errors, you don't want `wasm-pack` rubbing it in, right?)

This is an interesting one! `fitzgen` very reasonably filed an issue asking to add `wasm-bindgen`'s
`--target no-modules` feature to `wasm-pack`. This was confusing as this feature was indeed already implemented,
and documented- BUT, notably missing from the `wasm-pack --help` text. We've fixed that now- and it was an omission
so glaring we definitely considered it a bug!

- ### 🛠️ Maintenance
- **Replace `slog` with `log` - [alexcrichton], [issue/425] [pull/434]**
For internal maintenance reasons, as well as several end-user ones, we've migrated away from the `slog` family
of crates, and are now using the `log` crate plus `env_logger`. Now, `wasm-pack` won't create a `wasm-pack.log`.
Additionally, enabling logging will now be done through `RUST_LOG=wasm_pack` instead of `-v` flags.

- **Move binary installation to its own crate - [drager], [issue/384] [pull/415]**
In `wasm-pack 0.5.0`, we move away from `cargo install`ing many of the tools that `wasm-pack` orchestrates. Because
we used `cargo install`, this required an end user to sit through the compilation of each tool, which was a
prohibitively long time. We moved, instead, to building, and then installing, binaries of the tools. This sped up
build times dramatically!
This pattern has been very beneficial to `wasm-pack` and is potentially something that could be beneficial to other
projects! As a result, we've refactored it out into a crate and have published it as it's own crate, [`binary-install`].

- **Replace internal `Error` with `failure::Error` - [alexcrichton], [pull/436]**
The story of error message handling in `wasm-pack` has not been the prettiest. We originally were manually implementing
errors, adding the [`failure` crate] at one point, but not fully updating the entire codebase. With this PR, we are
nearly completely handling errors with `failure`, bringing the code into a much more maintainable and
pleasant-to-work-on place.

This is a very fun one since it fixes one of the original issues filed by `ag_dubs` at the very beginning of `wasm-pack`
development. In a rush to implement a POC tool, `ag_dubs` noted for posterity that the `Cargo.toml` was being read
multiple times (twice), when it did not need to be. Thanks to `fitzgen` now it's read only once! A minor performance
improvement in the scheme of things, but a nice one :)

- **Child Process and output management - [fitzgen], [issue/287] [pull/392]**
Not exactly a "fix", but definitely a huge improvment in how child processes and their
output are handled by `wasm-pack`. Ever sat at a long prompt from `wasm-pack` and
wondered what was happening? No longer! Did `wasm-pack` eat your test output- no more!

- **Less scary missing field messages - [mstallmo], [issue/393] [pull/394]**
After watching a livestream of someone using `wasm-pack`, [fitzgen] noted that folks
seemed pretty alarmed by the loud warning about missing optional manifest fields.
As a result, we are now downgrading those messages from WARN to INFO, and consolidating
them on a single line.

In 0.5.0 we removed all forced nightly usage as we depend on `~1.30` which is now
available on both nightly and beta channels! We had a bit of a race condition with
that PR and the `wasm-pack test` PR, and missed a few as a result! This removes all
lingering forced nightly, which only affected the `wasm-pack test` command.

## ☀️ 0.5.0
- ### ✨ Features
- #### **Website!** - [ashleygwilliams], [pull/246]
We have a website now. It has the installer and links to documentation. In the future,
we hope to have calls to action for folks first coming to the site who are looking to
do specific things- these will help them find the docs and tutorials they need to.
This PR also has a complete rework of our documentation.
Check it out [here](https://rustwasm.github.io/wasm-pack/)!
- #### 🍱 Module Support
- **BREAKING: use correct `package.json` keys for generated JavaScript - [ashleygwilliams], [issue/309] [pull/312]**
This is marked as potentially breaking because it changes the `package.json` keys that
are generated by the project.
Previously, we generated a JavaScript file and placed it in the `main` key, regardless
of what you were targeting, ES6 and Node.js alike.
We have received a lot of requests for `wasm-pack` to generate "isomorphic" packages,
that contain assets that could work on both Node.js and ES6, and this led to us
looking more closely at how we are using `package.json`.
With this release, we will do the following:
- `--target browser`: By default, we generate JS that is an ES6 module. We used to put
this in the `main` field. Now we put it in the `module` field. We also add
`sideEffects: false` so that bundlers that want to tree shake can.
- `--target nodejs`: This target doesn't change. We put generated JS that is a
CommonJS module in the `main` key.
- `--target no-modules`: This is a new target. For this target we generate bare JavaScript.
This code is put in a `browser` field.
You can see the structs that represent each target's expected `package.json` [here](https://github.com/rustwasm/wasm-pack/tree/master/src/manifest/npm).
Thanks so much to [bterlson] for his help in sorting this out for us!

- #### 🛠️ New Commands
- **`wasm-pack init` is now `wasm-pack build` - [csmoe], [issue/188] [pull/216]**
When this project was first conceived, we imagined it would be simply a way to package
up generate wasm and js and publish it to npm. Here we are at version `0.5.0` and we
have become much more- an integrated build tool!
As a result, the original command `init` does a lot more than that these days. We've
renamed the command to better reflect the work it's actually doing. `init` will still
work, but is deprecated now, and we will eventually remove it.

This is an experimental new command that will run your tests in Node.js or a headless
browser using `wasm-pack test`. Check out this [tutorial](https://rustwasm.github.io/wasm-bindgen/wasm-bindgen-test/index.html)

[pull/271]: https://github.com/rustwasm/wasm-pack/pull/271
- **add 2FA support to `wasm-pack publish` - [mstallmo], [issue/257] [pull/282]**
We've been wrapping the `npm login` and `npm publish` commands as `wasm-pack login`
and `wasm-pack publish` for a while now- but we didn't fully support two factor
authentication. Now we do! (Be safe out there! 2FA is good for everyone!)

[pull/282]: https://github.com/rustwasm/wasm-pack/pull/282
- #### 🎏 New Flags
- **New target, bare JavaScript: `--target no-modules` - [ashleygwilliams], [issue/317] [pull/327]**
`wasm-bindgen` offers a `no-modules` flag that until now, we didn't support. This flag
produces bare, no modules JavaScript. So if that's your thing, this target is for you!
[issue/317]: https://github.com/rustwasm/wasm-pack/issues/317
[pull/327]: https://github.com/rustwasm/wasm-pack/pull/327
- **`--access` flag for `wasm-pack` publish - [ashleygwilliams], [issue/297] [pull/299]**
Many of our tutorials use scopes to help prevent folks from attempting to publish
packages that will lead to npm Registry errors because the package name already exists.
However, by default, scoped packages are assumed by the npm registry to be private, and
the ability to publish private packages to the npm registry is a paid feature. Worry not!
Now you can pass `--access public` to `wasm-pack publish` and publish scoped packages
publicly.

[pull/299]: https://github.com/rustwasm/wasm-pack/pull/299
- #### ✅ New Checks
- **rustc version check - [ashleygwilliams], [issue/351] [pull/353]**
Now that we have a new fangled installer, there's a chance that folks might install `wasm-pack`
and not have Rust installed. Additionally, now that the features we required from the `nightly`
channel of Rust have moved to `beta`- we don't need to enforce `nightly`.
As of this release, we will check that your Rust version is above `1.30.0`. You can be on
either the `nightly` or `beta` channel and all of `wasm-pack`s calls to `cargo` will
respect that.
Really hate this? You can pass `--mode force` to `wasm-pack` to skip this check. I hope you know
what you're doing!
- **coordinating wasm-bindgen versions and installing from binaries for improved speed - [datapup], [issue/146] [pull/244] [pull/324]**
This is the true gem of this release. Have you been frustrated by how long `wasm-pack` takes to
run? Overusing `--mode no-install`? This is the release you're looking for.
Many releases back we realized that folks were struggling to keep the `wasm-bindgen` library
that their project used in sync with the `wasm-bindgen` CLI application which `wasm-pack`
runs for you. This became such an issue that we opted to force install `wasm-bindgen` to ensure
that every `wasm-pack` user had the latest version.
Like many technical solutions, this solved our original problem, but caused a new one. Now, we
we are forcing a `cargo install` of `wasm-bindgen` on every run, and that means downloading
and compiling `wasm-bindgen` everytime you want to run `wasm-pack`. That's unacceptable!
We're happy to announce that we have a pretty great solution, and several more planned for
future releases. As of this release, we will read your `Cargo.lock` to find the version of
`wasm-bindgen` you are using in your local project. We will attempt to fetch a binary version
of `wasm-bindgen` that matches your local version. We place that binary local to your project,
and use it when you run `wasm-pack build`. The next time you run `wasm-pack build` we'll use
that binary, instead of fetching a new one. We still fall back to `cargo install` for
less common architectures but this is a huge speed improvement. Check out these benchmarks!

- **enforce `cargo build` with `--lib` - [ashleygwilliams], [issue/303] [pull/330]**
Right now, `wasm-pack` only works on Rust library projects. But sometimes, if you're
new to Rust, you might end up having a `main.rs` in your project, just by mistake.
Some folks ran into this and realized that it can cause issues!
As a result, we are enforcing that `cargo build` only build the library at this time.
Want to use `wasm-pack` on a binary application? We're interested in hearing from you!
Checkout [issue/326] and please comment! We want to support binary applicaitons in
the future and are always happy and curious to hear about how folks use `wasm-pack`!

- **new experimental installer - [alexcrichton], [pull/307]**
Whew, this one is exciting. Up until now, `wasm-pack` has been distributed using
`cargo install`. This is not ideal for several reasons. Updating is confusing,
and every time it's installed the user has to wait for it to compile- right at the
moment they just want to hurry up and use it already.
Say hello to the new `wasm-pack` installer- we have an executable for Windows
and a `curl` script for *nix users. Not pleased with that? File an issue for your
preferred distribution method and we'll do our best to get it working!
This is experimental- so please try it out and file issues as you run into things!
You'll always be able to use `cargo install` as a backup.

## ✨ 0.4.2
- #### 🤕 Fixes
- **recognize `[dependencies.wasm-bindgen]` during dep check in `init` - [ashleygwilliams], [issue/221] [pull/224]**
When we originally implemented the dependency check in `wasm-pack init` we naively only checked for the
"simple" dependency declaration, `[dependencies] wasm-bindgen="0.2"`. However! This is not the only way
to declare this dependency, and it's not the ideal way to do it if you want to specify features from the
crate. Now that a bunch of folks want to use `features = ["serde-serialize"]` we ran into a bunch of folks
having issues with our naive dependency checker! Thanks so much to [turboladen] for filing the very detailed
issue that helped us solve this quickly!
PSSSST! Curious what `features = ["serde-serialize"]` with `wasm-bindgen` actually does? It's awesome:
> It's possible to pass data from Rust to JS not explicitly supported in the [Feature Reference](./feature-reference.md) by serializing via [Serde](https://github.com/serde-rs/serde).

Previous to this fix, you would need to be in the parent directory of the `/pkg` dir to successfully run
`pack` or `publish`. This was pretty crummy! Thankfully, [Mackiovello] swooped in with a fix, that you can
find documented in the [pack and publish docs]!

- **use `PathBuf` instead of `String` for paths - [Mackiovello], [pull/220]**
This is mostly a maintenance PR but does fix one very small bug- depending on if you add a trailing slash to
a path that you pass to `init`, you might have seen an extra `/`! Now that we're using a proper Type to
handle this, that's much better, and in general, all the operations using paths are more robust now.

We became aware that the `files` key in `package.json` did not include the additional `_bg.js` file that
`wasm-bindgen` generates for projects being built for the `nodejs` target. This resulted in the file not
being included in the published package and resulted in a `Module Not Found` error for folks.
This was a group effort from [mciantyre] with [pull/200] and [Brooooooklyn] with [pull/197]. Thank you so
much for your diligence and patience while we sorted through it.

- **DOCUMENT EVERYTHING!! and deny missing docs for all future development - [fitzgen], [pull/208]**
The `wasm-pack` team has worked hard on tutorial documentation and keeping the codebase as self-explanatory
as possible, but we have been slowly accruing a documentation debt. This amazing PR, landed just moments
before this point release and was just too good not to include. Thank you so much, [fitzgen]!

## 🌟 0.4.0
This release has a ton of awesome things in it, but the best thing is that
almost all of this awesome work is brought to you by a **new** contributor
to `wasm-pack`. Welcome ya'll! We're so glad to have you!
### ✨ Features
- #### 🎏 New Flags
- **`--mode` flag for skipping steps when calling `init` - [ashleygwilliams], [pull/186]**
After teaching and working with `wasm-pack` for some time, it's clear that people would
like the flexibility to run some of the steps included in the `init` command and not others.
This release introduces a `--mode` flag that you can pass to `init`. The two modes currently
available are `skip-build` and `no-installs` and they are explained below. In the future,
we are looking to change the `init` interface, and potentially to split it into two commands.
If you have thoughts or opinions on this, please weigh in on [issue/188]!

[pull/186]: https://github.com/ashleygwilliams/wasm-pack/pull/186
- **`skip-build` mode - [kohensu], [pull/151]**
```
wasm-pack init --mode skip-build
```
Sometimes you want to run some of the shorter meta-data steps that
`wasm-pack init` does for you without all the longer build steps. Now
you can! Additionally, this PR was a fantastic refactor that allows even
more custom build configurations will be simple to implement!
[kohensu]: https://github.com/kohensu
[pull/151]: https://github.com/ashleygwilliams/wasm-pack/pull/151
- **`no-installs` mode - [ashleygwilliams], [pull/186]**
```
wasm-pack init --mode no-installs
```
Sometimes you want to run `wasm-pack` and not have it modify your global
env by installing stuff! Or maybe you are just in a hurry and trust your
env is set up correctly- now the `--mode no-install` option allows you to
do this.
- **`--debug` - [clanehin], [pull/127]**
```
wasm-pack init --debug
```
Find yourself needing to compile your Rust in `development` mode? You can now
pass the `--debug` flag to do so! Thanks so much to [clanehin] for filing
[issue/126] for this feature... and then implementing it!

- #### ✅ New Checks
- **ensure you have `cdylib` crate type - [kendromelon], [pull/150]**
One of the biggest mistakes we've seen beginners make is forgetting to declare
the `cdylib` crate type in their `Cargo.toml` before running `wasm-pack init`.
This PR fixes that, and comes from someone who ran into this exact issue learning
about `wasm-pack` at [JSConfEU]! Love when it works out like this.

[pull/150]: https://github.com/ashleygwilliams/wasm-pack/pull/150
- **ensure you have declared wasm-bindgen as a dep - [robertohuertasm], [pull/162]**
Another easy mistake to make is to forget to declare `wasm-bindgen` as a
dependency in your `Cargo.toml`. Now `wasm-pack` will check and make sure you
have it set before doing a bunch of long build steps :)
[robertohuertasm]: https://github.com/robertohuertasm
[pull/162]: https://github.com/ashleygwilliams/wasm-pack/pull/162
- **ensure you are running `nightly` - [FreeMasen], [pull/172]**
`wasm-pack` currently requires that you run it with `nightly` Rust. Now, `wasm-pack`
will make sure you have `nightly` installed and will ensure that `cargo build` is run
with `nightly`. Thanks so much to [FreeMasen] for filing [issue/171] and fixing it!

### 🤕 Fixes
- **fixed broken progress bar spinner - [migerh], [pull/164]**
Oh no! We broke the progress bar spinner in version 0.3.0. Thankfully, it's
fixed now- with a thoughtful refactor that also makes the underlying code
sounder overall.
[migerh]: https://github.com/migerh
[pull/164]: https://github.com/ashleygwilliams/wasm-pack/pull/164
### 🛠️ Maintenance
- **WIP bot - [ashleygwilliams] & [mgattozzi], [issue/170]**
We've got a lot of work happening on `wasm-pack` so it's good to have a bit
of protection from accidentally merging a Work In Progress. As a result, we
now have the [WIP Github App] set up on `wasm-pack`. Great suggestion [mgattozzi]!
[WIP Github App]: https://github.com/wip/app
[issue/170]: https://github.com/ashleygwilliams/wasm-pack/issues/170
- **modularize `command.rs` - [ashleygwilliams], [pull/182]**
Thanks to the growth of `wasm-pack`, `command.rs` was getting pretty long.
We've broken it out into per command modules now, to help make it easier to
read and maintain!
[pull/182]: https://github.com/ashleygwilliams/wasm-pack/pull/182
- **improve PoisonError conversion - [migerh], [pull/187]**
As part of the awesome progress bar spinner fix in [pull/164], [migerh] introduced
a small concern with an `unwrap` due to an outstanding need to convert `PoisonError`
into `wasm-pack`'s custom `Error`. Though not a critical concern, [migerh] mitigated
this right away by replacing `std::sync::RwLock` with the [`parking_lot` crate]!
This cleaned up the code even more than the previous patch!
[`parking_lot` crate]: https://github.com/Amanieu/parking_lot
[pull/187]: https://github.com/ashleygwilliams/wasm-pack/pull/187
- **wasm category for crates.io discovery- [TomasHubelbauer], [pull/149]**
[crates.io] has [categories] to help folks discover crates, be we weren't
leveraging it! Now- if you explore the [`wasm` category] on [crates.io]
you'll see `wasm-pack`!

### 📖 Documentation
- **cleaned up the README - [ashleygwilliams], [pull/155]**
Our `README` was struggling with a common problem- doing too much at once.
More specifically, it wasn't clear who the audience was, contributers or
end users? We've cleaned up our README and created a document specifically
to help contributors get up and running.

## 🌠 0.3.1
Babby's first point release! Are we a real project now?
### 🤕 Fixes
- **fixed `init` `Is a Directory` error - [ashleygwilliams], [pull/139]**
Our new logging feature accidentally introduced a regression into 0.3.0. When
calling `wasm-pack init`, if a directory was not passed, a user would receive
a "Is a Directory" Error. Sorry about that! Thanks to [jbolila] for filing
[issue/136]!

- **typescript files were not included in published package - [danreeves], [pull/138]**
Generating Typescript type files by default was a pretty rad feature in
0.3.0 but we accidentally forgot to ensure they were included in the
published package. Thanks so much to [danreeves] for catching this issue
and fixing it for us!
[danreeves]: https://github.com/danreeves
[pull/138]: https://github.com/ashleygwilliams/wasm-pack/pull/138
## 💫 0.3.0
### ✨ Features
- **Logging - [mgattozzi], [pull/134]**
Up until now, we've forced folks to rely on emoji-jammed console output to debug
errors. While emojis are fun, this is often not the most pleasant experience. Now
we'll generate a `wasm-pack.log` file if `wasm-pack` errors on you, and you can
customize the log verbosity using the (previously unimplemented) verbosity flag.
[pull/134]: https://github.com/ashleygwilliams/wasm-pack/pull/134
- **`--target` flag - [djfarly], [pull/132]**
`wasm-bindgen-cli` is able to generate a JS module wrapper for generated wasm files
for both ES6 modules and CommonJS. Up until now, we only used wasm-bindgen's default
behavior, ES6 modules. You can now pass a `--target` flag with either `nodejs` or
`browser` to generate the type of module you want to use. Defaults to `browser` if not
passed.
[djfarly]: https://github.com/djfarly
[pull/132]: https://github.com/ashleygwilliams/wasm-pack/pull/132
- **human readable panics - [yoshuawuyts], [pull/118]**
Panics aren't always the most friendly situation ever. While we never want to panic on ya,
if we do- we'll do it in a way that's a little more readable now.
[pull/118]: https://github.com/ashleygwilliams/wasm-pack/pull/118
- **typescript support by default - [kwonoj], [pull/109]**
`wasm-bindgen` now generates typescript type files by default. To suppress generating
the type file you can pass the `--no-typescript` flag. The type file is useful for more
than just typescript folks- many IDEs use it for completion!
[kwonoj]: https://github.com/kwonoj
[pull/109]: https://github.com/ashleygwilliams/wasm-pack/pull/109
- **wrap `npm login` command - [djfarly], [pull/100]**
In order to publish a package to npm, you need to be logged in. You can now use
`wasm-pack login` to login to the npm (or any other) registry.
[pull/100]: https://github.com/ashleygwilliams/wasm-pack/pull/100
- **exit early on failure - [mgattozzi], [pull/90]**
Until now, `wasm-pack` would continue to run tasks, even if a task failed. Now- if something
fails, we'll exit so you don't have to wait to fix the error.
[pull/90]: https://github.com/ashleygwilliams/wasm-pack/pull/90
### 🤕 Fixes
- **force install wasm-bindgen - [ashleygwilliams], [pull/133]**
Using an out of date version of `wasm-bindgen` can run you into a bunch of trouble. This
very small change should fix the large number of bug reports we received from users using
an out of date `wasm-bindgen-cli` by force installing `wasm-bindgen-cli` to ensure the user
always has the latest version. We don't expect this to be a forever solution (it's a bit
slow!) but it should help those who are getting started have a less rough time.
[pull/133]: https://github.com/ashleygwilliams/wasm-pack/pull/133
- **fix CI release builds - [ashleygwilliams], [pull/135]**
This was not working! But now it is! You can always use `cargo install` to install
wasm-pack, but now you can find pre-built Linux and Mac binaries in the [Releases]
tab of our GitHub repo.

### 🛠️ Maintenance
- **remove `quicli` dependency - [mgattozzi], [pull/131]**
While `quicli` is a great way to get started writing a CLI app in Rust- it's not meant for
large, mature applications. Now that `wasm-pack` is bigger and has many active users, we've
removed this dependency to unblock further development on the tool.
[pull/131]: https://github.com/ashleygwilliams/wasm-pack/pull/131
- **update rustfmt CI test - [djfarly], [pull/128]**
Since 0.2.0 how one should call `rustfmt` changed! We've kept it up to date so we can continue
to maintain conventional style in the codebase.
[pull/128]: https://github.com/ashleygwilliams/wasm-pack/pull/128
- **custom module for errors - [mgattozzi], [pull/120]**
Thanks to the `failure` crate, we've been playing fast and loose with errors for a bit. We're
finally getting serious about error handling - by organizing all of our specific errors in a
specific module. This will make it easier to communicate these errors out and handle new error
cases from future features.
[pull/120]: https://github.com/ashleygwilliams/wasm-pack/pull/120
### 📖 Documentation
Special thanks to [data-pup] who continues to be our documentation champion! In case you missed it,
check out the guides in the [docs directory!](docs)!
## 🌌 0.2.0
This release focuses on filling out all commands and improving stderr/out
handling for improved user experience!
### ✨ Features
- **`pack` and `publish` - [jamiebuilds], [pull/67]**
You can now run `wasm-pack pack` to generate a tarball of your generated package,
as well as run `wasm-pack publish` to publish your package to the npm registry.
Both commands require that you have npm installed, and the `publish` command requires
that you be logged in to the npm client. We're working on wrapping the `npm login`
command so that you can also login directly from `wasm-pack`, see [pull/100] for more
details.

Previously, `package.json` was not very human readable. Now it is pretty printed!
- **`collaborators` - [yoshuawuyts], [pull/70]**
`wasm-pack` now will fill out the `collaborators` field in your `package.json` for
you based on your `Cargo.toml` `authors` data. For more discussion on how we decided
on this v.s. other types of `author` fields in `package.json`, see [issues/2].
