# `Cargo.toml` Configuration
|
|
|
|
`wasm-pack` can be configured via the `package.metadata.wasm-pack` key in
|
|
`Cargo.toml`. Every option has a default, and is not required.
|
|
|
|
There are three profiles: `dev`, `profiling`, and `release`. These correspond to
|
|
the `--dev`, `--profiling`, and `--release` flags passed to `wasm-pack build`.
|
|
|
|
The available configuration options and their default values are shown below:
|
|
|
|
```toml
|
|
[package.metadata.wasm-pack.profile.dev]
|
|
# Should `wasm-opt` be used to further optimize the wasm binary generated after
|
|
# the Rust compiler has finished? Using `wasm-opt` can often further decrease
|
|
# binary size or do clever tricks that haven't made their way into LLVM yet.
|
|
#
|
|
# Configuration is set to `false` by default for the dev profile, but it can
|
|
# be set to an array of strings which are explicit arguments to pass to
|
|
# `wasm-opt`. For example `['-Os']` would optimize for size while `['-O4']`
|
|
# would execute very expensive optimizations passes
|
|
wasm-opt = ['-O']
|
|
|
|
[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
|
|
|
|
[package.metadata.wasm-pack.profile.profiling]
|
|
wasm-opt = ['-O']
|
|
|
|
[package.metadata.wasm-pack.profile.profiling.wasm-bindgen]
|
|
debug-js-glue = false
|
|
demangle-name-section = true
|
|
dwarf-debug-info = false
|
|
|
|
# `wasm-opt` is on by default in for the release profile, but it can be
|
|
# disabled by setting it to `false`
|
|
[package.metadata.wasm-pack.profile.release]
|
|
wasm-opt = false
|
|
|
|
[package.metadata.wasm-pack.profile.release.wasm-bindgen]
|
|
debug-js-glue = false
|
