wasm-pack init
The wasm-pack init command creates the files neccessary for JavaScript
interoperability and for publishing a package to npm. This involves compiling
your code to wasm and generating a pkg folder. This pkg folder will contain the
wasm binary, a JS wrapper file, your README, and a package.json file.
Path
The wasm-pack init command can be given an optional path argument, e.g.:
wasm-pack init examples/js-hello-world
This path should point to a directory that contains a Cargo.toml file. If no
path is given, the init command will run in the current directory.
Scope
The init command also accepts an optional --scope argument. This will scope
your package name, which is useful if your package name might conflict with
something in the public registry. For example:
wasm-pack init examples/js-hello-world --scope test
This command would create a package.json file for a package called
@test/js-hello-world. For more information about scoping, you can refer to
the npm documentation here.
