一个 MYSQL 数据库的常用操作封装,使用连续点操作,实现语义化的数据库操作。
npm i @hyoga/mysql
const mysql = require('@hyoga/mysql').default;
// import mysql from '@hyoga/mysql';
const inst = new mysql({
host: '127.0.0.1',
user: 'root',
password: '',
database: 'test-db',
port: 3306,
});
const users = await inst.table('user').where({ status: 1 }).select();
console.log(users);
