npm install --save-dev rollup-plugin-livereload

// rollup.config.js
import livereload from 'rollup-plugin-livereload'

export default {
  input: 'entry.js',
  output: { file: 'bundle.js' },
  plugins: [livereload()],
}

To make it a real dev-server, combine this plugin with rollup-plugin-serve.

// rollup.config.js
import serve from 'rollup-plugin-serve'
import livereload from 'rollup-plugin-livereload'

export default {
  input: 'entry.js',
  output: { file: 'bundle.js' },
  plugins: [
    serve(), // index.html should be in root of project
    livereload(),
  ],
}

By default, it watches the current directory. If you also have css output, pass the folder to which the build files are written.

This plugin supports the following options:

• clientUrl: provide an alternative URL to the livereload.js script/resource. This URL is always preferred over all other generated URLs.
• clientHostname: alternative hostname used instead of localhost or the site's current host, where the bundle is fetched from. Use this option when you include your bundle from a different host.

All remaining options are passed to livereload.createServer().

Example:

livereload('dist')

// --- OR ---

livereload({
  watch: 'dist',
  verbose: false, // Disable console output

  // other livereload options
  port: 12345,
  delay: 300,
  https: {
      key: fs.readFileSync('keys/agent2-key.pem'),
      cert: fs.readFileSync('keys/agent2-cert.pem')
  }
})
