Micro-front end, future of frontend architecture.
Before moving into Micro frontend lets understand the evolution of software architecture. Software usually contains 3 layers. frontend, backend and storage (DB). Front end will be in the form of a user interface, And the backend will normally have your main business logic. Storage is where the data is stored. Earlier we used to have a monolithic application where your front and backend used to be bundled in one application. They used to reside in a single code repository. This entire application used to be maintained by 1 large team. For changing anything in the application you need to test the entire application because even a small change can break any part of the application that is unrelated to the change. Industry soon realized the need to split the front end and back-end part of the code. This enabled a specialized team for frontend and backend. Later backend services started using Microservices to decouple the code and improve scaling. Microservices architecture resolved m
