AngularJS - Services

Share reusable application logic and data access through injectable services.

How it works

Services are singleton-style injectable objects useful for shared logic and data access. Keep them focused, make dependencies explicit, and return clear asynchronous results. Avoid storing unrelated application state in a catch-all service.

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.
