The Facade Pattern in Angular helps in managing state and keeping projects clean, organized, and easier to work with over time.
A typical Facade Pattern consists of a service responsible for managing data and fetching it from an API, a facade service that simplifies interaction between components and the underlying service, and clean components that only interact with the facade.
Jasmine, a popular testing framework for Angular, can be used for unit testing the facade to ensure proper delegation of calls and functionality.
However, the introduction of a facade layer in small applications may unnecessarily complicate the architecture, and the pattern can make debugging harder due to hidden implementation details.
