super-orm

基于 Node.js 的 MySQL ORM 模块，支持缓存、多 MySQL 连接，支持 TypeScript

安装

$ npm install super-orm --save

环境要求

• Node.js v6.0 及更高版本 - 运行环境
• MySQL 5.6 及更高版本 - SQL 数据存储
• Redis 2.6 及更高版本 - 缓存存储

使用

'use strict';
 
const { Manager } = require('super-orm');
 
const manager = new Manager({
  // Redis 连接，用于缓存
  // 参考 https://github.com/luin/ioredis/blob/master/API.md#new_Redis
  redis: {
    host: '127.0.0.1',
    port: 6379,
    db: 0,
    password: '',
  },
  // 缓存 key 前缀
  prefix: 'TEST:',
  // 缓存世界，秒
  ttl: 60,
  // MySQL 连接，可指定多个，第一个为 Master，其余为 Slave
  // 参考 https://www.npmjs.com/package/mysql#connection-options
  connections: [
    {
      host: '127.0.0.1',
      port: 3306,
      user: 'root',
      password: '',
      database: 'test',
      connectionLimit: 10,
      charset: 'utf8mb4',
    },
    {
      host: '127.0.0.1',
      port: 13306,
      user: 'root',
      password: '',
      database: 'test',
      connectionLimit: 10,
      charset: 'utf8mb4',
    },
  ],
});
 
// 注册 Model
manager.registerModel('User', {
  table: 'users',
  primary: 'id',
  autoIncrement: true,
  fields: {
    // true 表示该字段存在
    id: true,
    name: true,
    email: true,
    // 可指定字段为 json 类型，在存储是会自动对数据执行 JSON.stringify()，读取时执行 JSON.parse()
    // 或自定义 encode 和 decode 方法
    info: 'json',
    created_at: 'date',
    // 其它未定义的字段在存储时会被自动过滤
  },
});
 
// 使用 Model
manager.model('User').getByPrimary({ id: 123 })
  .then(ret => console.log(ret))
  .catch(err => console.error(err));
// 所有接口同时支持 callback 和 promise
manager.model('User').getByPrimary({ id: 123 }, (err, ret) => {
  if (err) console.log(err)
  console.log(ret);
});
 
// 使用原始连接执行查询，SELECT 语句会在任意连接执行，其它语句只在 Master 连接执行
manager.connection.query('CREATE TABLE `hello`')
  .then(ret => console.log(ret))
  .catch(err => console.error(err));
 
// 事务（在 Master 连接执行）
(async function () {
  const conn = await manager.connection.getMasterConnection();
  // 开始事务
  await conn.beginTransaction();
  try {
    await conn.query('INSERT INTO `hello`...');
    await conn.query('INSERT INTO `hello`...');
    await conn.query('INSERT INTO `hello`...');
    // 提交事务
    await conn.commit();
  } catch (err) {
    // 回滚事务
    await conn.rollback();
  }
  // 释放连接
  await conn.release();
})();
