Description: The Dependency Injection Token in Angular is a unique identifier used to inject dependencies into the components and services of an application. This mechanism is fundamental in Angular’s dependency injection system, allowing developers to manage the creation and lifecycle of objects efficiently. Tokens can be simple, such as strings or symbols, or more complex, like classes. Their use enables Angular to automatically resolve the dependencies required by a component or service, facilitating code modularity and reuse. Additionally, tokens are essential for configuring injectors, which are responsible for providing instances of the requested dependencies. This feature not only improves code organization but also promotes separation of concerns, resulting in more maintainable and scalable applications. In summary, the Dependency Injection Token is a key piece in Angular’s architecture, allowing for efficient dependency management and contributing to the creation of robust and well-structured applications.
