koa-json-body

koa-json-body

Very simple koa middleware wrapper around co-body for parsing JSON request bodies. Largely inspired by koa-body.

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

Installation

npm install koa-json-body --save

Options

Available via co-body:

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

Usage

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);
});
