receive-json

Receive JSON over an HTTP request.

Install

npm install receive-json

Usage

Example

var http = require('http');
var onjson = require('receive-json');
 
http.createServer(function(req, res) {
  onjson(req, function(err, body) {
    if (err) {
      res.statusCode = 400;
      return res.end('oh no!');
    }
    res.end('awesome!');
  });
}).listen(3000);

The following example uses the limit option, which allows you to limit the size of the payload to prevent users from overcharging your server. The limit is passed as number of bytes.

var http = require('http');
var onjson = require('receive-json');
 
http.createServer(function(req, res) {
  onjson(req, {limit: 10000}, function(err, body) {
    if (err) {
      res.statusCode = 400;
      return res.end('oh no!');
    }
    res.end('awesome!');
  });
}).listen(3000);

Defaults

You can also call the .defaults function to have default settings applied to every call of the function. Like this.

var http = require('http');
var onjson = require('receive-json');
 
onjsonlimit = onjson.defaults({limit: 10000});
 
http.createServer(function(req, res) {
  onjsonlimit(req, function(err, body) { // this call has the limit applied to it.
    if (err) {
      res.statusCode = 400;
      return res.end('oh no!');
    }
    res.end('awesome!');
  });
}).listen(3000);
