@yolodev/rollup-config-lerna v0.3.1

@yolodev/rollup-config-lerna

Config for lerna based monorepos that builds all packages using a single rollup bundler.

Usage

Currently two different "modes" is supported in rollup-config-lerna, with more planned for later. The first mode (perPackage mode) uses a separate rollup.config.js in each package. To use this, put a rollup.config.js in the root directory (next to lerna.json) with the following content:

// rollup.config.js
import { perPackage } from '@yolodev/rollup-config-lerna';

export default perPackage();

This mode will fail if any of the packages does not have a rollup.config.js.

The second mode currently support is using a common config file for all modules. To use this mode, first create a rollup.lerna.js file in the root folder (next to lerna.json), and put something like the following in it:

// rollup.lerna.js
export default (project, pkg, cmdOpts) => {
  return {
    input: './src/index.js',
    output: {
      file: './dist/index.js',
      format: 'cjs',
    },
    plugins: [],
  };
};

Then, in rollup.config.js put the following:

// rollup.config.js
import { common } from '@yolodev/rollup-config-lerna';

export default common();
