Origami v2 brings a lot of exciting changes! The library features a new build system architecture using polymer-webpack-loader. It patches the Angular CLI to inject this loader using the patch-cli.js script.

Check out the README.md for more details on the new and improved build process.

Code Refactoring

util: remove getter functions for Polymer/ShadyCSS/customElements (c479759)

BREAKING CHANGES

The emitChanges directive has been removed. It was slow and not all that useful for two-way binding. It's much better to either use ironControl and [(ngModel)] or manually hook into the (property-changed) event.

Before

<paper-checkbox [(checked)]="isChecked" emitChanges></paper-checkbox>

After

<paper-checkbox
  [checked]="isChecked"
  (checked-changed)="isChecked = $event.detail.value"
></paper-checkbox>
<!-- or -->
<paper-checkbox [(ngModel)]="isChecked" ironControl></paper-checkbox>

Collections have been removed. The ironControl directive will no longer be automatically applied to elements. If you want to use Angular forms ([(ngModel)] or formControlName), you will need to add the ironControl directive manually.

Before

<paper-input [(ngModel)]="value"></paper-input>

After

<paper-input [(ngModel)]="value" ironConrol></paper-input>

util: The utility functions to get the Polymer/ShadyCSS/customElements properties have been removed. Instead typings are provided in the repo to access window.Polymer and window.ShadyCSS
