This article mainly introduces the node.js express mvc lightweight framework example analysis, has a certain reference value, interested friends can refer to the next, I hope you read this article after a lot of gains, the following let Xiaobian with everyone to understand.

In fact, there is nothing to talk about logic, mainly to talk about this code structure. The structure is as follows:

JS code is more difficult to maintain, it is not clear whether we agree with this point, but here the author only said his feelings, the author's friends began to find the author, said to play color, has been staring at play, will be because of greed will mess, want to do an automatic betting system, let the program play by itself. At first, the author just wanted to perfunctory, directly take node.js +express to complete the following set of structures.

Basic and express sample code are no different. However, with the change of requirements, I feel that maintenance is becoming more and more difficult, helpless, can only do it again.

This set of node.js express mvc code structure I was learning nodeclub open source project, interested friends can go to learn. Briefly explain the meaning of each part of the code below:

API---------------------> API logic processing layer, generally CURD and other operations of data

controllers------> C terminal site, nothing to say

jobs-----------------

logs---------------> File logs

models -----------> mongoose database links and entity definitions

proxy ------------> Encapsulation of database access methods, such as insert, update

util-----------------> Tools js wrapper, such as DateFormat

views-------------> page layers, ejs page rendering engine

api_router.js----> api routing

web_router.js---> web page routing

The app.js-------------

Why did the author do this? MVC code layering, although the amount of code invisible increase, but the purpose is for better management, means that significantly reduce maintenance costs, the advantages outweigh the disadvantages.

Incidentally, node-schedule and pm2 process managers in multi-process mode, there will be repeated execution problems, the author's solution is to divide the web and jobs into multiple process managers.

Thank you for reading this article carefully. I hope that the article "node.js express mvc lightweight framework example analysis" shared by Xiaobian will help everyone. At the same time, I hope that everyone will support it a lot and pay attention to the industry information channel. More relevant knowledge is waiting for you to learn!
