toor

toor makes it easy to take a worker out of rotation.

When using cluster, it's easy enough to take a worker out of rotation from inside the worker. Just close() the server, and then call listen() again when you want to bring it back again.

In many cases, it's more logical to control which workers are in rotation from the master process. That's where toor comes in handy.

Usage

First of all, require toor near the top of your file.

const toor = require('toor')

From your master process, you can call toor.pause(worker, cb) on a worker. The callback is called when all connections are done and the worker is no longer accepting new requests.

toor.pause(worker, () => console.log('this worker is now paused!'))

To have the worker start accepting requests again, call toor.unpause(worker, cb) on it.

toor.unpause(worker, () => console.log('this worker is now unpaused!'))

WARNING: toor is invasive. It does a lot of shimming in the net, http and cluster modules. If you're not comfortable with that, I'm sorrry!
