Remix CLI

The Remix CLI comes from the @remix-run/dev package. It also includes the compiler. Make sure it is in your package.json devDependencies so it doesn't get deployed to your server.

Commands

remix build

Builds your app for production. No need to add NODE_ENV=production to the command.

remix build

remix watch

Watches your application files and builds your app for development when files change.

remix watch

remix dev

Same as watch but also boots the Remix app server in development mode if it's installed.

remix dev

Note: The default port is 3000, but can be changed by setting the PORT environment variable. If you are changing this to run multiple instances of Remix, you must also set unique Dev websocket ports via remix.config.js or setting REMIX_DEV_SERVER_WS_PORT.
