Description: An Angular module is a cohesive block of code dedicated to an application domain, a workflow, or a closely related set of capabilities. In Angular, modules are fundamental for efficiently organizing and structuring applications. Each module can contain components, services, directives, and other modules, allowing for better code management and greater reuse. Modules facilitate lazy loading, meaning they can be loaded only when needed, thus improving application performance. Additionally, modules help encapsulate functionalities, promoting separation of concerns and code maintainability. In summary, modules are an essential part of Angular’s architecture, enabling developers to build scalable and well-organized applications.
History: Angular was developed by Google, and its first version, AngularJS, was released in 2010. Over time, significant improvements were made, and in 2016, Angular 2 was launched, adopting a component-based and modular approach. This evolution allowed developers to create more complex and scalable applications, using modules as a way to organize code more effectively.
Uses: Modules in Angular are used to group related functionalities, facilitating code organization and component reuse. They are employed in applications of any size, from small single-page applications to large enterprise systems. Additionally, they allow for lazy loading of parts of the application, optimizing performance.
Examples: A practical example of a module in Angular is the ‘FormsModule’, which provides functionalities for working with forms. Another example is the ‘HttpClientModule’, which allows making HTTP requests. These modules are imported into the main application module to enable their features.
