Simple koa middleware wrapper around co-body for parsing JSON request bodies.

This will not parse anythig but valid JSON request bodies. If there is a JSON parsing error, the middleware will set ctx.request.body to {} and continue.

This branch supports Koa 0.x and 1.x. For Koa 2 support (using Promises instead of Generators), please use the master branch.

npm install koa-json-body --save

Available via co-body:

• limit - number or string representing the request size limit (default: 1mb)

On a every route:

var jsonBody = require('koa-json-body');
app.use(jsonBody({ limit: '10kb' }));
app.use(function *() {
  console.log(this.request.body);
});

On a per-route basis (using koa-router):

var jsonBody = require('koa-json-body')({ limit: '10kb' });
app.post('/users', jsonBody, function *() {
  console.log(this.request.body);
});

Major versions will map to co-body major versions (e.g. koa-json-helmet 4.x.x uses co-body 4.y.y)
