Together with the Angular core team and John Papa, we're working on an official style guide which incorporates all the best practices from:
- Practices discovered during the internal usage of Angular 2 in Google.
- The previous version of this style guide, which can be found here.
- John Papa's AngularJS 1.x and Angular 2 style guides.
The previous version of the style guide can be found here.
