Find out how to use REST requests in your Angular 2 application to send data to a CouchDB server and how to correctly process your data for storage.
- [Narrator] Let's save the current value…of the user list filter to our server,…by updating our "onFilter" method,…to update the filter value on our server,…whenever the filter input in our UI changes.…We do this in our "onFilter" method in the component,…by referencing the "this.http.put" method.…The "put" method takes three arguments.…The first argument is a string,…representing the end point on the server for our data.…In our case, this would be…http://localhost:5984/user/settings.…
The second argument is the request body,…and the third argument is an object…of optional request settings.…For this request, we only need arguments one and two.…The first argument is the same URL string…we used earlier in this course,…when making the "http.get" request.…Since we're using the same string in more than one location,…it's good practice to pull this data out…into its own variable.…This will make updating the URL much easier…as our application grows more complex.…We do this by declaring a new variable…at the top of our class,…
