What is bundled into vendor.bundle.js?
angular, angular-cli, webpack
Solution
I think any modules imported into the app.module.ts file will show up in the vendor bundle.
Example app.module.ts:
@NgModule({
imports: [
BrowserModule,
CommonModule,
FormsModule,
RouterModule,
],
...
Problem
The angular-cli is producing `vendor.bundle.js` when executing a build. What are the rules of what is going to be considered packed under `vendor.bundle.js`?
