Find out how to add REST requests to your Angular 2 application to get and set data in a CouchDB database.
- Let's add methods to our web storage service,…that allow users to save the current filter state…to our couch DB database.…We start by creating a new import statement at the top…of our web storage service file, and importing the http…class from the angular/http module.…We'll also need to import the http module class into our…app module file, which gives our entire application…access to the necessary rest services we need…to communicate with our server.…
We do this by opening the app module file,…and creating a new import statement, importing…the http module class from angular/http.…We'll also need to add the http module class to our list…of imports in the NG module decorator.…Back on our web storage service file, we'll instantiate…the http class, in a constructor function, by typing…a new line, followed by constructor, and between the…parentheses, we'll type private http, and set it…to the http class type.…
We'll then create a new method called getRemote,…which will use the http instance to get the filter state…
