import { DataSource } from 'typeorm';
import * as path from 'path';

const entityExtension = __filename.endsWith('.ts') ? 'ts' : 'js';

export const MysqlDataSource = new DataSource({
  type: 'mysql',
  host: '127.0.0.1', //MYSQLHOST
  port: 3306, //MYSQLPORT
  username: 'root', //MYSQLUSERNAME
  password: '1234.com', //MYSQLPASSWORD
  database: 'linda', //MYSQLDATABASE
  synchronize: false,
  entities: [path.join(__dirname, `../mysqlentity/*.${entityExtension}`)],
  // logging: true
});

　　

 

 

  host: process.env.MYSQLHOST || '10.143.32.2', //MYSQLHOST

  port: parseInt(process.env.MYSQLPORT || '3002'), //MYSQLPORT

  username: process.env.MYSQLUSERNAME || 'root', //MYSQLUSERNAME
