Talk to a remote server with an HTTP Client. HTTP is the primary protocol for browser/server communication. The WebSocket protocol is another important communication technology; we won't cover it in this chapter. Modern browsers support two HTTP-based APIs: XMLHttpRequest (XHR) and JSONP. A few browsers also support Fetch. The Angular HTTP library simplifies application programming of the XHR and JSONP APIs as we'll learn in this chapter covering: HTTP client sample overview Fetch data with

Angular's hierarchical dependency injection system supports nested injectors in parallel with the component tree. We learned the basics of Angular Dependency injection in the Dependency Injection chapter. Angular has a Hierarchical Dependency Injection system. There is actually a tree of injectors that parallel an application's component tree. We can reconfigure the injectors at any level of that component tree with interesting and useful results. In this chapter we explore these points and wri
