Output usage information

Examples

  • Starts a server in development mode using https and port 3002

npx frontity dev --https --port 3002
  • Starts a server in development mode using the folder assets as the path for statics

npx frontity dev --public-path="/assets"

The --production option

This flag correspond to webpack’s mode parameter so it will run webpack in the production mode as described there before launching the development server.

So, if you do:

npx frontity dev --production

The webpack bundler internally will do things like..

  • Enable certain webpack-specific optimizations and minify the code

  • Also disable hot-module reloading (HMR)

  • Not create source maps

  • Append hashes to filenames so for caching purposes

Normally, you would always use the development server in development mode, but sometimes you may want to check that everything works in production mode, or check the bundle analyzer (the files at /build/analyze) for the production bundle.
