Support Koa 2

[felixsanz]

This library doesn't have a @next tag? Only generators?

Also would be nice if the examples were a bit more clear. I can't still manage to get it working and documentation is not so friendly.

I think this works now with lru-cache because their API is like:

set(key, value, maxAge)
get(key) => value

Both of these will update the "recently used"-ness of the key. They do what you think. maxAge is optional and overrides the cache maxAge option if provided.

Hi there! I've solved it like this, and it seems to be working.

const cash = require('koa-cash');
const convert = require('koa-convert');
const LRU = require('lru-cache');

const cache = LRU(1000);
app.use(convert(cash({
  get: key => cache.get(key),
  set: (key, value) => cache.set(key, value)
})));

app.use(async (ctx, next) => {
  const cashed = await ctx.cashed();
  if (cashed) return;
  await next();
});

@lbeschastny I created a version with Koa 2 support: https://github.com/joukosaastamoinen/cash/tree/koa-2-support

If there was a branch for the next version, I could create a pull request.

@joukosaastamoinen I've created a next branch and pulled your code there.

I've also published it under next tag to npm.

Now all I need is a confirmation that it works fine with koa@2.

@lbeschastny I just took it into use in a small production app with Koa 2, and seems to work fine. I confirmed that responses are actually cached.

Did we bin support for Koa 2?
