ECMAScript module (ESM) bundle support #148

Open LoganDupont opened 3 years ago

LoganDupont commented 3 years ago

Currently using moment-duration-format in an Angular version 10+ application gives the following build warning:

WARNING in [filename] depends on 'moment-duration-format'. CommonJS or AMD dependencies can cause optimization bailouts.
For more info see: https://angular.io/guide/build#configuring-commonjs-dependencies

Starting with Angular 10 the Angular CLI now provide warnings for CommonJS modules. Read more about it here: https://blog.angular.io/version-10-of-angular-now-available-78960babd41

When you use a dependency that is packaged with CommonJS, it can result in larger slower applications. Starting with version 10, we now warn you when your build pulls in one of these bundles. If you’ve started seeing these warnings for your dependencies, let your dependency know that you’d prefer an ECMAScript module (ESM) bundle.

And here: https://angular.io/guide/build#configuring-commonjs-dependencies

It is recommended that you avoid depending on CommonJS modules in your Angular applications. Depending on CommonJS modules can prevent bundlers and minifiers from optimizing your application, which results in larger bundle sizes. Instead, it is recommended that you use ECMAScript modules in your entire application. For more information, see How CommonJS is making your bundles larger

Is it possible to add ESM support?
