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 app = koa();

app.use(json());

app.use(function *(next){
  this.body = { foo: 'bar' };
});

yields:

$ GET /

{
  "foo": "bar"
}

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

var app = koa();

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

app.use(function *(next){
  this.body = { foo: 'bar' };
});

yields:

$ GET /

{"foo":"bar"}

$ GET /?pretty

{
  "foo": "bar"
}
