@videojs/babel-config

Currently babel configs are the same for most plugins, and most of them are built using this babel config via babel. We have some libraries though that are should not be built using rollup for nodejs consumption, that are currently doing so. So this config while still consumed by videojs-generate-rollup-config can also be used standalone with babel-cli.

Installation

$ npm install --save-dev @babel/cli @videojs/babel-config

Usage

1. In your rollup config add a line to delete module builds:

if (config.builds.module) {
	delete config.builds.module;
}

2. Add a npm scripts for cjs/es dists to your package.json:

{
  "build:cjs": "babel-config-cjs -d ./dist/cjs ./src",
  "build:es": "babel-config-es -d ./dist/cjs ./src",
  "watch:cjs": "npm run build:cjs -- -w",
  "watch:es": "npm run build:es -- -w"
}

3. verify that main in package.json is set to the cjs dist. Something like dist/cjs/index.js
4. verify that module in package.json is set to the es dist. Something like dist/es/index.js
5. verify that browser in package.json is set to the browser dist. Something like dist/project-name.js

Important things

• When running through babel-config-cjs, babel-config-es, or babel-config-run if TEST_BUNDLE_ONLY is set nothing will run!
• The babel-config-cjs binary runs babel cli with --verbose and --config-file set to the cjs config exported here.
• The babel-config-es binary runs babel cli with --verbose and --config-file set to the es config exported here.
• The babel-config-run binary runs babel cli with --verbose but no config file.

Changing configuration

1. require the configuration you want to use const config = require('@videojs/babel-config/cjs.js');
2. Make changes to it and export: module.export = config.
3. pass --config-file <path> in the above scripts so that everything points to your new configs.
4. change the above script to use babel-config-run
