The Cookbook offers answers to common implementation questions.
Each cookbook page is a collection of recipes focused on a particular Angular feature or application challenge such as data binding, cross-component interaction, and communicating with a remote server via HTTP.
The cookbook is just getting started. Many more recipes are on the way.
Each cookbook links to a live sample with every recipe included.
Recipes are deliberately brief and code-centric. Each recipe links to a relevant page of the Developer Guide or the API Reference where you can learn more about the purpose, context, and design choices behind the code snippets.
Post documentation requests and comments as issues on the angular.io github repository. Fixes (small ones) are greatly appreciated as pull requests.
Post issues with Angular itself to the angular github repository.
