BFF#

In the development of the concept of front back separation, the front-end part can do more and more things, and the front-end needs some UI-oriented data interfaces, so the industry introduced the concept of BFF (Backends for Frontends).

The main problems it to solve include:

• Aggregation, mapping, clipping, and proxying of lower-level APIs according to their own business needs.
• Cache data for some specific scenarios to improve performance and thus improve user experience.
• Quickly development of new products based on existing interfaces.
• Interface with third-party systems, such as login authentication.

Modern.js officially supported the BFF and provided the Integrated BFF to further strengthen the BFF's capabilities, mainly including the following capabilities:

• Quick development and debugging go live, running, building, and deploying BFF code in the same project.
• Minimal pure function call, directly import BFF function on the front end, and can be automatically converted into HTTP request when called.
• No private protocol, follow RESTful API specification, all BFF interfaces are standardized.
• Full TypeScript support.
• Meet user preferences and support multi-frame extension writing.
