one-sys gogogo!

This scaffold is mainly dedicated to the quick development framework of front-end engineers, such as quick development and one-click deployment. The main purpose is to enable front-end engineers to quickly develop and deploy their own projects on an Aliyun server. In line with the logic of front-end and back-end integration, some wheels are integrated and some scaffolding tools are added. It is the first time to develop scaffolding. If you have any questions, please put forward on the issue. If there is any help for you, please give a star~

  • Front-end integration: vue-cli3.0, axios, element, etc.
  • Command line tool integration: commander, chalk, figlet, shelljs, etc.
  • Back-end integration: node, koa2, koa-mysql-session, mysql, etc.
  • Server Consolidation: nginx, pm2, node, etc
  • Polymerization separation

The so-called aggregation and separation, first is’ aggregation’, aggregation code, aggregation plug-in, accomplish a project can complete the front-end code writing, packaging online and other functions of aggregation. This was followed by’ separation’. The front and rear ends are separated. Although the code will be in the same project project, the front and back ends will not interfere with each other and will be online respectively, which is different from the conventional rendering mode of ejs and other service ends, so that the front ends are completely separated.

  • One-touch deployment

Based on local command-line tools, static files at view end can be quickly packaged and uploaded to ariyun server, and files at server end can also be quickly uploaded to server folder, so as to carry out code hot update in coordination with pm2 monitoring function and seamlessly update interface logic

  • Fast iteration

Basic use cases are provided, including container cases and component cases in the view layer at the front end, api settings of components and middleware logic that integrates axios, so as to facilitate users to quickly build their own projects. the code is clear and easy to analyze and modify. the server side simply encapsulates mysql connection pool and releases it in time after connection is completed. table tables and functions are layered. the code is layered into routing layer, controller layer and sql operation layer


1. Login page

  • Login-correct feedback error feedback session settings after successful login
  • Registration-Duplicate Name Detection Correct Feedback Error Feedback
  1. Main module functions
  • Implementation of Basic Functions of Module Addition, Deletion, Query and Modification
  1. Background koa2 service module
  • Cooperate with koa-mysql-session to store session settings
  • Implementation of checkLogin Middleware
  • Cors Cross-Domain Whitelist Setting
  • Setting of Middleware Middleware
  • Encapsulation of mysql Connection Pool

Wait. . .

  1. Server side
  • The basic configuration of nginx is separated from the front end
  • Json
  1. Local debugging
  • Install mysql (process please Baidu)
//Enter sql Command Line
 $ mysql -u root -p
 //Create a database named nodesql
 $ create database nodesql
  • Install pm2 (process please Baidu)
  • Pull project code
git clone
 cd ONE-sys
 //install plug-ins
 Cnpm i or npm i or yarnad
 //install link
 sudo npm link
 //Then you can use the command line tool
 one start
 //or students who do not want to use the command line can
 yarn run serve
  • Code logic


  • server


  • bin

  • Starting effect
Start project
 yarn run v1.3.2
 $ pm2 restart ./server/index.js && vue-cli-service serve
