Parse json request body, generator style.
It seems that similar modules don't provide sane stack traces, or simply ignore errors. Because this one is completly generator-based, it provides proper stacktraces on parse error.
$ npm install koa-parse-json
var koa = require('koa');
var body = require('koa-parse-json');
var app = koa();
app.use(body());
app.use(function* () {
this.body = this.request.body;
});Returns a koa middleware, that can parse JSON request body.
It stops reading after opts.limit bytes, and throws 413,
if Content-Length doesn't match with request length, 400 is throwed.
Default opts.limit is 1MB.
