Node.js http basic auth

Passport provides a clean mechanism to implement basic auth. I use it in my Node.js Express app to protect both my Angularjs-based UI as well as my RESTful API. To get passport up and running in your app do the following:

• npm install passport

• npm install passport-http (contains "BasicStrategy" object for basic auth)

• Open up your app.js and add the following:

  var passport = require('passport')    
  var BasicStrategy = require('passport-http').BasicStrategy
  
  passport.use(new BasicStrategy(
    function(username, password, done) {
      if (username.valueOf() === 'yourusername' &&
        password.valueOf() === 'yourpassword')
        return done(null, true);
      else
        return done(null, false);
    }
  ));
  
  // Express-specific configuration section
  // *IMPORTANT*
  //   Note the order of WHERE passport is initialized
  //   in the configure section--it will throw an error
  //   if app.use(passport.initialize()) is called after
  //   app.use(app.router) 
  app.configure(function(){
    app.use(express.cookieParser());
    app.use(express.session({secret:'123abc',key:'express.sid'}));
    app.set('views', __dirname + '/views');
    app.set('view engine', 'jade');
    app.set('view options', {
      layout: false
    });
    app.use(express.bodyParser());
    app.use(express.methodOverride());
    app.use(express.static(__dirname + '/public'));
    app.use(passport.initialize());
    app.use(app.router);
    app.use(logger);
  });
  
  // Routes
  
  app.get('/', passport.authenticate('basic', { session: false }), routes.index);
  app.get('/partials/:name', routes.partials);
  
  // JSON API
  
  app.get('/api/posts', passport.authenticate('basic', { session: false }), api.posts);
  app.get('/api/post/:id', passport.authenticate('basic', { session: false }), api.post)
  // --Repeat for every API call you want to protect with basic auth--
  
  app.get('*', passport.authenticate('basic', { session: false }), routes.index);
