Jetpack wraps webpack and nodemon to give you the best development workflow.

  const rspackConfig = !options.target.modern ? rspackConfigs.legacy : rspackConfigs.modern
  rspackConfig.plugins = rspackConfig.plugins || []

  const compiler = rspack(rspackConfig)
  compiler.run(async function (err, stats) {
