koa-accepts

Simple middleware to change the format of your response based on the HTTP accept header, using q weights via the negotiator library.

Supported formats:

• application/yaml: YAML
• application/x-msgpack: MsgPack
• application/json: JSON.stringify

If anything else it will fall back to doing what koa normally does (JSON).

Quickstart

import * as koa from 'koa'
import accepts from 'koa-accepts'
 
const app = new Koa()
 
app.use(accepts())
