koa-json

JSON pretty-printed response middleware. Also converts node object streams to binary.

Installation

$ npm install koa-json

Options

• pretty default to pretty response [true]
• param optional query-string param for pretty responses [none]
• spaces JSON spaces [2]

Example

Always pretty by default:

const json = require('koa-json')
const Koa = require('koa')
const app = new Koa()

app.use(json())

app.use((ctx) => {
  ctx.body = { foo: 'bar' }
})

// @request: GET /
//
// @response:
// {
//   "foo": "bar"
// }

Default to being disabled (useful in production), but togglable via the query-string parameter:

const Koa = require('koa')
const app = new Koa()

app.use(json({ pretty: false, param: 'pretty' }))

app.use((ctx) => {
  ctx.body = { foo: 'bar' }
})

// @request: GET /
//
// @response:
// {"foo":"bar"}

// @request: GET /?pretty
//
// @response:
// {
//   "foo": "bar"
// }
