Support Koa 2

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.

@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.

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();
});
