koa-json v2.0.2

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:

var json = require('koa-json');
var Koa = require('koa');
var app = new Koa();

app.use(json());

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

yields:

$ GET /

{
  "foo": "bar"
}

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

var Koa = require('koa');
var app = new Koa();

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

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

yields:

$ GET /

{"foo":"bar"}

$ GET /?pretty

{
  "foo": "bar"
}
