AngularJS - Custom Directives
Create reusable directives with clear scope, template, and lifecycle behavior.
How it works
A custom directive can define a template, bindings, controller, and lifecycle hooks. Prefer a component when building a self-contained UI element. Keep DOM manipulation isolated, define input and output contracts, and release resources on destruction.
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.
