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
