Simple front-end and back-end separation can be achieved by adding a proxy or uniformly using the jsonp interface to achieve synchronous front-end and front-end separation development. Disadvantages: The template function cannot be used. The interface can only use ajax form, which is not friendly to search engines.
Modular front-end and back-end separation, the front-end web part runs completely independently, including front-end code and back-end code; the back-end service runs independently, providing data and computing services.
