What are the best practices for using directives in Angular CLI?

When using directives in Angular CLI, it's important to follow a few best practices: 1. Use meaningful names for your directives. 2. Keep your directives focused on a single responsibility. 3. Use the appropriate lifecycle hooks. 4. Avoid manipulating the DOM directly; use Angular's Renderer2 instead.

Can you explain why it's important to use meaningful names?

Meaningful names improve code readability and maintainability. They help other developers understand the purpose of the directive at a glance, making collaboration easier.

What are some common mistakes to avoid with directives?

Common mistakes include: 1. Overusing directives for simple tasks, 2. Not isolating scope properly, 3. Failing to clean up resources in lifecycle hooks, and 4. Directly manipulating the DOM instead of using Angular's tools.

How can I test my directives effectively?

To test directives effectively, use Angular's testing utilities like TestBed. Write unit tests to check the directive's behavior, and use tools like Jasmine and Karma for running your tests.
