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.

To get a full list of available commands and flags, run:

npx @remix-run/dev -h

remix create

remix create will create a new Remix project. Without passing arguments, this command will launch an interactive CLI to configure the new project and set it up in a given directory. Optionally you can pass the desired directory path as an argument and a starter template with the --template flag.

remix create <projectDir>

remix create --template

A valid template can be:

  • a directory located in the templates folder of the Remix repository
  • a local file path to a directory of files
  • a local file path to a tarball
  • the name of a :username/:repo on GitHub
  • the URL of a remote tarball
remix create ./my-app --template fly
remix create ./my-app --template /path/to/remix-template
remix create ./my-app --template /path/to/remix-template.tar.gz
remix create ./my-app --template remix-run/grunge-stack
remix create ./my-app --template :username/:repo
remix create ./my-app --template
remix create ./my-app --template
remix create ./my-app --template
remix create ./my-app --template
remix create ./my-app --template

remix build

Builds your app for production. This command will set process.env.NODE_ENV to production and minify the output for deployment.

remix build

remix build --sourcemap

Generates sourcemaps for the production build.

remix watch

Watches your application files and builds your app for development when changes are made.

remix watch

remix dev

The same as watch, but also boots the Remix App Server in development mode if it's installed.

remix dev

remix dev --debug

Attaches a Node inspector to develop your app in debug mode.

remix dev --port

Launches the app server on a given port.

By default, the port is set to 3000. If port 3000 is unavailable, the dev command will attempt to find another port that is open. Using the --port flag will only attempt to launch the server at the given port; if the port is unavailable, the app will not start.

remix dev --port 4001

Alternatively, a port can be assigned to the PORT environment variable.
