Implementing Social Login in Feathers.js

Feathers.js is a popular Node.js framework for building real-time applications and RESTful APIs. One of the key features of modern web applications is social login, which allows users to authenticate using their existing social media accounts. In this article, we will explore how to implement social login in Feathers.js.

Prerequisites

To implement social login in Feathers.js, you need to have the following:

• A Feathers.js application set up and running
• A social media developer account (e.g., Facebook, Google, Twitter)
• A client-side library for handling social login (e.g., Passport.js)

Step 1: Set up Social Media Developer Account

Before you can implement social login in your Feathers.js application, you need to set up a social media developer account. This will provide you with the necessary credentials (e.g., client ID, client secret) to authenticate users.

Here are the steps to set up a social media developer account for popular social media platforms:

Facebook

To set up a Facebook developer account, follow these steps:

1. Go to the Facebook Developer Dashboard and create a new app
2. Fill in the required information (e.g., app name, namespace)
3. Click on "Add Product" and select "Facebook Login"
4. Configure the Facebook Login settings (e.g., redirect URI)
5. Click on "Save Changes" to save the app settings

Google

To set up a Google developer account, follow these steps:

1. Go to the Google Cloud Console and create a new project
2. Click on "Navigation menu" and select "APIs & Services" > "Dashboard"
3. Click on "Enable APIs and Services" and search for "Google Sign-In API"
4. Click on "Create credentials" and select "OAuth client ID"
5. Configure the OAuth client ID settings (e.g., authorized redirect URI)
6. Click on "Create" to create the OAuth client ID

Step 2: Install Passport.js

Passport.js is a popular client-side library for handling social login. To install Passport.js, run the following command:

npm install passport

Step 3: Configure Passport.js

To configure Passport.js, you need to create a new instance of the Passport class and configure the social media strategies.

Here is an example of how to configure Passport.js for Facebook and Google:

const passport = require('passport');
const FacebookStrategy = require('passport-facebook').Strategy;
const GoogleStrategy = require('passport-google-oauth20').Strategy;

passport.use(new FacebookStrategy({
  clientID: 'YOUR_FACEBOOK_CLIENT_ID',
  clientSecret: 'YOUR_FACEBOOK_CLIENT_SECRET',
  callbackURL: 'http://localhost:3030/auth/facebook/callback'
}, (accessToken, refreshToken, profile, cb) => {
  // Handle Facebook authentication
}));

passport.use(new GoogleStrategy({
  clientID: 'YOUR_GOOGLE_CLIENT_ID',
  clientSecret: 'YOUR_GOOGLE_CLIENT_SECRET',
  callbackURL: 'http://localhost:3030/auth/google/callback'
}, (accessToken, refreshToken, profile, cb) => {
  // Handle Google authentication
}));

Step 4: Implement Social Login in Feathers.js

To implement social login in Feathers.js, you need to create a new authentication service that uses Passport.js.

Here is an example of how to create a new authentication service that uses Passport.js:

const feathers = require('@feathersjs/feathers');
const authentication = require('@feathersjs/authentication');
const passport = require('passport');

const app = feathers();

app.configure(authentication({
  strategies: ['facebook', 'google'],
  passport: passport
}));

app.service('authentication').hooks({
  before: {
    create: [
      authentication.hooks.authenticate(['facebook', 'google'])
    ]
  }
});
