express-http-support

This is an Express middleware to make the Express response object hold all the (most widely known) HTTP status codes and HTTP headers, as methods.

1. Installation

~$ npm install -s express-http-support

2. Usage

1. Import the module and add the 2 middlewares (for the HTTP status codes and for the headers):

var express = require("express");
 
// 0) Instantiate an Express application:
var app = express();
 
// 1) Get the module:
var httpSupport = require("express-http-support");
 
// 2) Add all the HTTP status codes:
app.use(httpSupport.status.middleware);
 
// 3) Add all the HTTP headers:
app.use(httpSupport.headers.middleware); 

2. Access the HTTP status codes or headers from any middleware or controller directly:

Example of HTTP status code modification 1:

app.get("/", function(req, res, next) {
  res.statusOK().send("Normal response");
});

Example of HTTP status code modification 2:

app.get("/nocontent", function(req, res, next) {
  res.statusNoContent().send();
});

Example of HTTP header modification 1:

app.get("/referrer", function(req, res, next) {
  res.headerContentType("application/json").send("Content type altered");
});

Example of HTTP header modification 2:

app.get("/nocontent", function(req, res, next) {
  res.statusNoContent().send();
});

4. Conclusion

Following the same programmatic API that express brings by itself, where we can find the HTTP methods available as properties of the {Express Application} object, I wanted to expand the same idea to the HTTP status codes and the HTTP headers too, but in this case, in the {Express Response} object.
