feathers-authentication-custom

Custom authentication strategy for feathers-authentication using Passport

Installation

npm install feathers-authentication-custom --save

API

This module is a wrapper around the passport-custom strategy which allows you implement a custom verifier function for authenticating requests.

Main Initialization

In most cases initializing the feathers-authentication-custom module is as simple as doing this:

app.configure(authentication(settings));
app.configure(custom((req, done) => {
    // implement your own custom logic for loading and verifying the user
    done(null, user);
}));

If you use a function declaration instead of an arrow => function, then you can use this.app to get a reference to the app object:

function verifier (req, done) {
    this.app === app; //-> true
}
app.configure(authentication(settings));
app.configure(custom(verifier));

Verifier class

In more advanced scenarios you can use a Verifier class. This should be familiar to you if you have ever used a custom verifier class with other passport strategies. The class should implement the following methods:

class CustomVerifier {
    constructor(app, options) {} // the class constructor
    verify(req, done) {} // performs custom verification
};
 
app.configure(authentication(settings));
app.configure(custom({ Verifier: CustomVerifier }));

Expected Request Data

By default, this strategy expects a payload in this format:

{
  strategy: 'custom'
}

Complete Example

Here's a basic example of a Feathers server that uses feathers-authentication-jwt. You can see a fully working example in the example/ directory.

const feathers = require('feathers');
const rest = require('feathers-rest');
const hooks = require('feathers-hooks');
const memory = require('feathers-memory');
const bodyParser = require('body-parser');
const errorHandler = require('feathers-errors/handler');
const auth = require('feathers-authentication');
const custom = require('feathers-authentication-custom');
 
function verifier (req, done) {
  // perform custom verifications
  done(null, user);
}
 
// Initialize the application
const app = feathers()
  .configure(rest())
  .configure(hooks())
  // Needed for parsing bodies (login)
  .use(bodyParser.json())
  .use(bodyParser.urlencoded({ extended: true }))
  // Configure feathers-authentication
  .configure(auth({ secret: 'super secret' }))
  .configure(custom(verifier))
  .use('/users', memory())
  .use(errorHandler());
 
app.listen(3030);
 
console.log('Feathers app started on 127.0.0.1:3030');
