Purpose of the Exports Array
- Sharing Components, Directives, and Pipes: Angular applications often have multiple NgModules, each containing a set of related functionalities. By specifying certain components, directives, or pipes in the exports array, you can make them available for use in other NgModules. This helps in code reusability and avoids duplication of code across the application.
- Creating Reusable Libraries: The exports array plays a crucial role in creating reusable libraries or modules in Angular. You can package a set of components, directives, or pipes into a separate NgModule and expose them via the exports array.
- Encapsulation and Abstraction: While Angular allows modularity and encapsulation, it also allows selective exposure of functionalities to other parts of the application.
- Promoting Consistency and Best Practices: By declaring the exported components, directives, or pipes in an NgModule, you can establish a clear contract for consuming these functionalities in other parts of the application.
What is the Purpose of Exports Array in NgModule?
NgModule is a class marked by the @NgModule decorator. It identifies the module’s own components, directives, and pipes, making some of them public, through the exports property, so that external components can use them. The @NgModule decorator takes a metadata object as an argument. This object configures various aspects of the module, such as declarations, exports, imports, providers, and bootstrap.
