Lightweight, opinionated clustering for Koa apps. Use this if you don't want the complexity of other process managers.

koa-cluster app.js

You must export your Koa app like:

var app = module.exports = koa()

Make sure you don't create a http server yourself. Don't call app.listen(). This will handle it automatically.

This automatically utilizes the checkContinue event. You should handle this wherever appropriate in your Koa app:

app.use(function* () {
  if (this.req.checkContinue) this.res.writeContinue();
  var body = yield parse(this);
})

Custom settings are checked on the app that aren't part of Koa. You can set them however you'd like. These settings are:

• name - your app's name
• port
• hostname
• maxHeadersCount
• timeout
