Command Line Interface (CLI)

@rspack/cli provides two common subcommands, serve and build, to simplify daily work. If you do not have @rspack/cli installed, please read the Quick Start section first.

Compatible with webpack-cli

@rspack/cli is not going to be compatible with webpack-cli, so there will be many differences between the two.

Build

Run the rspack build command, which will generate the output files for production.

$ rspack build # Read the rspack.config.js configuration file by default
$ rspack build -c ./your.config.js

Serve

Running the Rspack development server command will start a local development server that will listen for file changes and automatically refresh the browser.

$ rspack serve
$ rspack serve -c ./your.config.js
