Description

Use standalone components instead of NgModules when possible to improve modularity, reduce boilerplate, and enable better tree-shaking.

When to use:

• New components - Always prefer standalone for new components unless there’s a specific need for NgModules
• Leaf components - Components that don’t need to declare other components
• Reusable components - Components intended for use across different parts of the application
• Library components - When building Angular libraries for better consumer experience

Benefits:

• Reduced Boilerplate - No need to create and maintain NgModule files
• Better Tree-shaking - Unused dependencies are more easily eliminated
• Improved Modularity - Each component manages its own dependencies
• Simpler Testing - Easier to set up component tests without module configuration
• Faster Development - Less configuration needed when creating new components

When NOT to use:

• Legacy applications where migration cost is too high
• When you need to provide global services at the module level
• Complex applications with deeply nested module hierarchies that serve a specific architectural purpose
• When working with third-party libraries that require NgModule integration
