Output or log the vite rollup configuration?

When we create a vite project running npm run build will create the rollup javascript bundle.

However the command npm init vite@latest that we used to scaffold out the project does not create a rollup.config.js file.

Is there a way to output the default rollup configuration, so we can see what the settings used to create the bundle?

Solution

  • One of the Vite Maintainers said no, but we can get some options via a plugin. The plugin implementation is below and here's a Stackblitz demo.

    export default {
  plugins: [
    {
      name: 'log',
      options(options) {
        console.log('options', options);
      },
      outputOptions(outputOptions) {
        console.log('outputOptions', outputOptions);
      },
    },
  ],
};
