MySQL with Node.js

Since this is an old thread just adding an update:

To install the MySQL node.js driver:

If you run just npm install mysql, you need to be in the same directory that your run your server. I would advise to do it as in one of the following examples:

For global installation:

npm install -g mysql

For local installation:

1- Add it to your package.json in the dependencies:

"dependencies": {
    "mysql": "~2.3.2",
     ...

2- run npm install

Note that for connections to happen you will also need to be running the mysql server (which is node independent)

To install MySQL server:

There are a bunch of tutorials out there that explain this, and it is a bit dependent on operative system. Just go to google and search for how to install mysql server [Ubuntu|MacOSX|Windows]. But in a sentence: you have to go to http://www.mysql.com/downloads/ and install it.


Check out the node.js module list

  • node-mysql — A node.js module implementing the MySQL protocol
  • node-mysql2 — Yet another pure JS async driver. Pipelining, prepared statements.
  • node-mysql-libmysqlclient — MySQL asynchronous bindings based on libmysqlclient

node-mysql looks simple enough:

var mysql      = require('mysql');
var connection = mysql.createConnection({
  host     : 'example.org',
  user     : 'bob',
  password : 'secret',
});

connection.connect(function(err) {
  // connected! (unless `err` is set)
});

Queries:

var post  = {id: 1, title: 'Hello MySQL'};
var query = connection.query('INSERT INTO posts SET ?', post, function(err, result) {
  // Neat!
});
console.log(query.sql); // INSERT INTO posts SET `id` = 1, `title` = 'Hello MySQL'

node-mysql is probably one of the best modules out there used for working with MySQL database which is actively maintained and well documented.
