node.js + mysql connection pooling

by

It’s a good approach.

If you just want to get a connection add the following code to your module where the pool is in:

var getConnection = function(callback) {
    pool.getConnection(function(err, connection) {
        callback(err, connection);
    });
};

module.exports = getConnection;

You still have to write getConnection every time. But you could save the connection in the module the first time you get it.

Don’t forget to end the connection when you are done using it:

connection.release();
