TypeError: Object #<Pool> has no method 'on'

[apparatusdeus]

In the documentation on the main page there is a block that reads as follows:

pool.on('connection', function(err, connection) {
  connection.query('SET SESSION auto_increment_increment=1')
});

However when I run this code I receive the following error:
TypeError: Object # has no method 'on'

I'm with the 2.0.0-alpha8 version and keeps with this issue

Having the same issue with 2.0.0.-alpha8, i have opened another issue for the same with the code I am using.

#561

There is no "on" method in the documentation for 2.0.0-alpha8 version:
https://github.com/felixge/node-mysql/tree/v2.0.0-alpha8

To use this method you need to download master branch of node-mysql.

When using master branch there is no error "TypeError: Object # has no method 'on'", but event is never called.

Note, per #599, the callback only has one parameter the connection.

pool.on('connection', function(connection) {});

Also note, there is a test for this event in master you can reference if it is still an issue. https://github.com/felixge/node-mysql/blob/master/test/integration/pool/test-connection-event.js

This issue can be closed. The reason you are getting the error is because you are not using at least v2.0.0-alpha9 as before then, the pool object was not an event emitter, so it had no on method.
