Hello wasm-pack!

Commands

wasm-pack has several commands to help you during the process of building a Rust-generated WebAssembly project.

• new: This command generates a new project for you using a template. Learn more
• build: This command builds a pkg directory for you with compiled wasm and generated JS. Learn more
• pack and publish: These commands will create a tarball, and optionally publish it to a registry, such as npm. Learn more Deprecated Commands
• init: This command has been deprecated in favor of build. Log levels

By default wasm-pack displays a lot of useful information.

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:

wasm-pack --log-level error build
wasm-pack --quiet build
wasm-pack --verbose build
