With the development of technology, the complexity of development is getting higher and higher. The traditional development method makes a system into a whole application. It often happens that a small change or the addition of a small function may cause the overall logic to change. The modification affects the whole body. Through component development, individual development and maintenance can be effectively achieved, and they can be combined at will. Greatly improve low development efficiency and reduce maintenance costs.
Componentization is the only way for any front-end application with complex business scenarios and products after multiple iterations. Componentization requires more than just the module splitting and decoupling seen on the surface. There is also a lot of work behind it to support componentization, such as module splitting strategies based on business characteristics, interaction methods between modules, and building systems. etc.
