dynamic-cdn-webpack-plugin
Dynamically get your dependencies from a cdn rather than bundling them in your app
Warning: This module is a fork from https://github.com/mastilver/dynamic-cdn-webpack-plugin. We start to fork after month without update and because we need to ship our libs and project over CDN leverage UMD builds.
The underlying module-to-cdn for the same reason has also been forked https://npmjs.org/package/@talend/module-to-cdn.
Install
$ npm install --save-dev @talend/dynamic-cdn-webpack-plugin @talend/module-to-cdn
