您需要使用pg driver
pg的文档
示例代码
npm i pg --save
或者你用的是Yarn
yarn add pg

const { Pool } = require('pg');

const dbConfig = {
  host: 'localhost',
  user: 'database-user',
  max: 20,
  idleTimeoutMillis: 30000,
  connectionTimeoutMillis: 2000,
};
 
const pool = new Pool(dbConfig);

pool
  .query('SELECT $1::text as name', ['brianc'])
  .then((res) => console.log(res.rows[0].name)) // brianc
  .catch((err) => console.error('Error executing query', err.stack))

使用MySQL
npm i mysql2 --save

const mysql = require('mysql2');

const connection = mysql.createConnection({
  host: 'localhost',
  user: 'root',
  database: 'test'
});

connection.query(
  'SELECT * FROM `table` WHERE `name` = "Page" AND `age` > 45',
  function(err, results, fields) {
    console.log(results); // results contains rows returned by server
    console.log(fields); // fields contains extra meta data about results, if available
  }
);
