Great God of Kneel to beg: How to Cooperate Best between Front and Rear Ends

  node.js, question

The output of PHP and JSP pages with dynamic data is completely independent of the packaging and publishing of front-end and back-end.
The advantage of this is the performance of the front-end layer. The data is completely controlled by the front-end.
What problems can be solved independently by the front end and packaged and released separately.

The packaging and publishing of front-end and back-end are completely independent. The meaning and understanding of this remark

Front-end separation, front-end engineering, front-end and back-end interaction all through api, you may think this is bad for seo, but now there is nodejs, so page rendering can be handed over to the front-end to do, in fact this is also a trend, the back-end should be concerned about system availability, performance and other issues, should not pay attention to page issues, this part should be handed over to the front-end
