http-auth

What is http-auth?

The http-auth npm package provides basic and digest access authentication for Node.js applications. It allows developers to secure their web applications by requiring users to provide a username and password before accessing certain routes or resources.

What are http-auth's main functionalities?

Basic Authentication

This feature allows you to set up basic authentication for your Node.js server. Users will need to provide a username and password to access the protected routes.

const http = require('http');
const auth = require('http-auth');

const basic = auth.basic({
  realm: 'Simon Area',
  file: __dirname + '/users.htpasswd' // user:password in htpasswd format
});

http.createServer(basic, (req, res) => {
  res.end(`Welcome to private area - ${req.user}!`);
}).listen(1337, () => {
  console.log('Server running at http://127.0.0.1:1337/');
});

Digest Authentication

This feature allows you to set up digest authentication for your Node.js server. Digest authentication is more secure than basic authentication as it uses MD5 hashing.

const http = require('http');
const auth = require('http-auth');

const digest = auth.digest({
  realm: 'Simon Area',
  file: __dirname + '/users.htdigest' // user:realm:password in htdigest format
});

http.createServer(digest, (req, res) => {
  res.end(`Welcome to private area - ${req.user}!`);
}).listen(1337, () => {
  console.log('Server running at http://127.0.0.1:1337/');
});

Other packages similar to http-auth

express-basic-auth

The express-basic-auth package provides basic authentication middleware for Express applications. It is simpler to use with Express compared to http-auth and integrates seamlessly with the Express framework.

passport-http

The passport-http package is a Passport strategy for HTTP Basic and Digest authentication. It is part of the Passport.js ecosystem, which provides a wide range of authentication strategies and is highly extensible.

basic-auth

The basic-auth package is a simple tool for parsing basic authentication headers. It does not provide full authentication middleware but can be used in conjunction with other packages to implement basic authentication.

Installation

Via git (or downloaded tarball):

$ git clone git://github.com/http-auth/http-auth.git

Via npm:

$ npm install http-auth

Basic example

// Authentication module.
var auth = require('http-auth');
var basic = auth.basic({
	realm: "Simon Area.",
	file: __dirname + "/../data/users.htpasswd"
});

// Creating new HTTP server.
http.createServer(basic, function(req, res) {
	res.end("Welcome to private area - " + req.user + "!");
}).listen(1337);

Custom authentication

// Authentication module.
var auth = require('http-auth');
var basic = auth.basic({
		realm: "Simon Area."
	}, function (username, password, callback) { 
	    // Custom authentication
	    // Use callback(error) if you want to throw async error.
		callback(username === "Tina" && password === "Bullock");
	}
);

// Creating new HTTP server.
http.createServer(basic, function(req, res) {
	res.end("Welcome to private area - " + req.user + "!");
}).listen(1337);

express framework integration

// Authentication module.
var auth = require('http-auth');
var basic = auth.basic({
	realm: "Simon Area.",
	file: __dirname + "/../data/users.htpasswd"
});

// Application setup.
var app = express();
app.use(auth.connect(basic));

// Setup route.
app.get('/', function(req, res) {
    res.send("Hello from express - " + req.user + "!");
});

koa framework integration

// Authentication module.
var auth = require('http-auth');
var basic = auth.basic({
    realm: "Simon Area.",
    file: __dirname + "/../data/users.htpasswd"
});

// Enable auth.
app.use(auth.koa(basic));

// Final handler.
app.use(function *() {
    this.body = "Hello from koa - " + this.req.user + "!";
});

Protecting specific path

// Authentication module.
var auth = require('http-auth');
var basic = auth.basic({
	realm: "Simon Area.",
	file: __dirname + "/../data/users.htpasswd"
});

// Application setup.
var app = express();

// Setup route.
app.get('/admin', auth.connect(basic), function(req, res) {
    res.send("Hello from admin area - " + req.user + "!");
});

// Setup route.
app.get('/', function(req, res) {
    res.send("Not protected area!");
});

passport integration

// Authentication module.
var auth = require('http-auth');
var basic = auth.basic({
	realm: "Simon Area.",
	file: __dirname + "/../data/users.htpasswd"
});

// Application setup.
var app = express();

// Setup strategy.
var passport = require('passport');
passport.use(auth.passport(basic));

// Setup route.
app.get('/', passport.authenticate('http', {session: false}),
    function(req, res) {
        res.end("Welcome to private area - " + req.user + "!");
    }
);

http-proxy integration

// Authentication module.
var auth = require('http-auth');
var basic = auth.basic({
	realm: "Simon Area.",
	file: __dirname + "/../data/users.htpasswd"
});

// Create your proxy server.
httpProxy.createServer(basic, {
    target: 'http://localhost:1338'
}).listen(1337);

// Create your target server.
http.createServer(function (req, res) {
	res.end("Request successfully proxied!");
}).listen(1338);

Configurations

• realm - Authentication realm, by default it is Users.
• file - File where user details are stored.
  • Line format is {user:pass} or {user:passHash} for basic access.
  • Line format is {user:realm:passHash} for digest access.
• algorithm - Algorithm that will be used only for digest access authentication.
  • MD5 by default.
  • MD5-sess can be set.
• qop - Quality of protection that is used only for digest access authentication.
  • auth is set by default.
  • none this option is disabling protection.
• msg401 - Message for failed authentication 401 page.
