egg-sequelize JS编写

1.安装Egg脚手架

npm i egg-init -g

2.通过脚手架创建Egg TS项目

egg-init xxx(项目名称) --type=ts
cd xxx
npm install

3.安装egg-requelize（当前安装的为js版本）

npm install --save egg-sequelize mysql2

4.在 config/plugin.js中引入 egg-sequelize 插件

exports.sequelize = {
    
  enable: true,
  package: 'egg-sequelize',
};

ts项目为config/plugin.ts

  sequelize: {
    
    enable: true,
    package: 'egg-sequelize',
  }

4.在 config/config.local.ts 中编写 sequelize 配置

  config.sequelize = {
    
    dialect: 'mysql',
    host: '127.0.0.1',
    username: 'root',
    password: '',
    port: 3306,
    database: 'it666',
  };

ts项目为config/config.local.ts

  config.sequelize = {
    
    dialect: 'mysql',
    host: '127.0.0.1',
    username: 'root',
    password: '',
    port: 3306,
    database: 'it666',
  };

5.在app目录下创建model目录，在model目录下创建user.ts

'use strict';

module.exports = app => {
    
  const {
     STRING, INTEGER, DATE } = app.Sequelize;

  const User = app.model.define('user', {
    
    id: {
     type: INTEGER, primaryKey: true, autoIncrement: true },
    name: STRING(30),
    age: INTEGER,
    created_at: DATE,
    updated_at: DATE,
  });

  return User;
};

6.control目录下的home.ts

import {
     Controller } from 'egg';

export default class HomeController extends Controller {
    
  public async index() {
    
    const {
     ctx } = this;
    // ctx.body = await ctx.service.test.sayHi('egg');
    ctx.body = await ctx.model.User.findAll();
  }
}

7.终端运得到数据库中users表的全部数据

 npm run dev
