AngularJS - AJAX

Request remote data asynchronously and present loading and error states.

How it works

The $http service sends asynchronous requests and returns promises. Keep request logic in a service, represent loading and failure states in the view, and handle server validation errors. Never rely on client-side checks as authorization.

Practice checklist

• Use examples that match the AngularJS version in the existing application.
• Keep user input, asynchronous states, and failures visible and understandable.
• Test keyboard access and validate important rules on the server.
• Review dependency support and migration needs before production changes.
