# Getting Started With the Node.js Connector

Complete Node.js connector guide for MariaDB. Complete reference for installation, connection pooling, query execution, and error handling for production use.

The MariaDB Node.js Connector is available through the Node.js repositories. You can install it using npm:

```bash
npm install mariadb
```

Using ECMAScript, prior to 2017:

```js
const mariadb = require('mariadb');
const pool = mariadb.createPool({
     host: 'mydb.com', 
     user:'myUser', 
     password: 'myPassword',
     connectionLimit: 5
});
pool.getConnection()
    .then(conn => {
    
      conn.query("SELECT 1 as val")
        .then((rows) => {
          console.log(rows); //[ {val: 1}, meta: ... ]
          //Table must have been created before 
          // " CREATE TABLE myTable (id int, val varchar(255)) "
          return conn.query("INSERT INTO myTable value (?, ?)", [1, "mariadb"]);
        })
        .then((res) => {
          console.log(res); // { affectedRows: 1, insertId: 1, warningStatus: 0 }
          conn.end();
          pool.end();
        })
        .catch(err => {
          //handle error
          console.log(err); 
          conn.end();
          pool.end();
        })
        
    }).catch(err => {
      //not connected
      pool.end();
    });
```

Using ECMAScript 2017:

```js
const mariadb = require('mariadb');
const pool = mariadb.createPool({
     host: 'mydb.com', 
     user:'myUser', 
     password: 'myPassword',
     connectionLimit: 5
});
async function asyncFunction() {
  let conn;
  try {
	conn = await pool.getConnection();
	const rows = await conn.query("SELECT 1 as val");
	console.log(rows); //[ {val: 1}, meta: ... ]
	const res = await conn.query("INSERT INTO myTable value (?, ?)", [1, "mariadb"]);
	console.log(res); // { affectedRows: 1, insertId: 1, warningStatus: 0 }

  } catch (err) {
	throw err;
  } finally {
	if (conn) conn.end();
  }
}
asyncFunction().then(() => {
  pool.end();
});
```

The MariaDB Connector has a [Promise](/docs/connectors/mariadb-connector-nodejs/connector-nodejs-promise-api.md) *(Default)* and callback API.

[Typescript specific docs are also available](/docs/connectors/mariadb-connector-nodejs/connector-nodejs-promise-api.md#typescript-usage).
