How might I access `ctx` outside of a middleware or a route?

I’m trying to implement socket.io to my app, and I want to have it work like sailsjs has, where you can do req.socket.emit or w/e.

I’m trying to add io to the ctx variable so that I could do something like

ctx.io.emit('hello', "Hello!");

But I can’t seem to find how to access ctx without binding the io to it in every single middleware request (only really needs to be a one time thing). Any information would be great thanks.

Sorry one more quick thing, is the app.context client specific, or will all connected people share the same clisock until a new one connects, or does each app.context have their own clisock

Each request receives a new ctx but that object inherits app.context, so it’ll be a shared clisock. Which for reference is here: https://github.com/koajs/koa/blob/master/lib/application.js#L134-L167
