Passport-HeaderAPIKey

Passport strategy for authenticating with a apikey.

This module lets you authenticate using a apikey in your Node.js applications which is used to build rest apis. By plugging into Passport, apikey authentication can be easily and unobtrusively integrated into any application or framework that supports Connect-style middleware, including Express.

Installation

$ npm install @neuralegion/passport-headerapikey

Usage

Configure Strategy

The api key authentication strategy authenticates users using a apikey. The strategy requires a verify callback, which accepts these credentials and calls done providing a user.

    const HeaderAPIKeyStrategy = require('passport-headerapikey').HeaderAPIKeyStrategy
    
    passport.use(new HeaderAPIKeyStrategy(
      { header: 'Authorization', prefix: 'Api-Key' },
      (apikey, done) => {
        User.findOne({ apikey: apikey }, (err, user) => {
          if (err) { return done(err); }
          if (!user) { return done(null, false); }
          return done(null, user);
        });
      }
    ));

Authenticate Requests

Use passport.authenticate(), specifying the 'headerapikey' strategy, to authenticate requests.

For example, as route middleware in an Express application:

app.post('/api/authenticate', 
  passport.authenticate('headerapikey', { session: false, failureRedirect: '/api/unauthorized' }),
  function(req, res) {
    res.json({ message: "Authenticated" })
  });

Examples

curl -v --header "Authorization: Api-Key asdasjsdgfjkjhg" http://127.0.0.1:3000/api/authenticate
