express-response

How can I use it?...

It's very simple

 
var express  = require('express');
var Response = require('express-response');
 
var app = express();
 
app.get('/', function (req, res) {
  Response.OK(res)({ message: 'Hello World!' })
});
 

Using it with Bluebird

 
var express  = require('express');
var Bluebird = require('bluebird');
var Response = require('express-response');
 
var app = express();
 
app.get('/', function (req, res) {
  Bluebird.resolve({ message: 'Hello World!' })
    .tap(__doSomething)
    .then(Response.OK(res))
    .catch(Response.INTERNAL_SERVER_ERROR(res));
});
 

Express response errors handle

 
var express  = require('express');
var Bluebird = require('bluebird');
var Response = require('express-response');
 
var ResponseError = Response.Error;
 
var app = express();
 
app.get('/', function (req, res) {
  Bluebird.resolve( req.body )
    .tap(function (body) {
      if (!body.value) {
        throw new ResponseError.BAD_REQUEST('Property "value" is mandatory')
      }
    })
    .get('value')
    .tap(function (value) {
      if (value !== 42) {
        throw new ResponseError.PAYMENT_REQUIRED('$$$$');
      }
    })
    .then(__doSomething)
    .then(Response.OK(res))
    .catch(ResponseError, Response.sendError(res));
});
