passport-coinbase-oauth20

Passport strategy for authenticating with Coinbase using the OAuth 2.0 API.

This module lets you authenticate using Google in your Node.js applications. By plugging into Passport, Google authentication can be easily and unobtrusively integrated into any application or framework that supports Connect-style middleware, including Express.

Install

$ npm install passport-coinbase-oauth20

Usage

Create an Application

Before using passport-coinbase-oauth20, you must create an account with Coinbase. Your application will be issued a client ID and client secret, which need to be provided to the strategy. You will also need to configure a redirect URI which matches the route in your application.

Configure Strategy

The Coinbase authentication strategy authenticates users using a Coinbase account and OAuth 2.0 tokens. The client ID and secret obtained when creating an application are supplied as options when creating the strategy. The strategy also requires a verify callback, which receives the access token and optional refresh token, as well as profile which contains the authenticated user's Coinbase profile. The verify callback must call cb providing a user to complete authentication.

var CoinbaseStrategy = require('passport-coinbase-oauth20').Strategy;

passport.use(
	new CoinbaseStrategy(
		{
			clientID: COINBASE_CLIENT_ID,
			clientSecret: COINBASE_CLIENT_SECRET,
			callbackURL: 'http://www.example.com/auth/coinbase/callback',
		},
		function(accessToken, refreshToken, profile, cb) {
			User.findOrCreate({ coinbaseId: profile.id }, function(err, user) {
				return cb(err, user);
			});
		},
	),
);

Authenticate Requests

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

For example, as route middleware in an Express application:

app.get('/auth/coinbase', passport.authenticate('coinbase', { scope: ['wallet:user:read', 'wallet:user:email'] }));

app.get('/auth/google/callback', passport.authenticate('coinbase', { failureRedirect: '/login' }), function(req, res) {
	// Successful authentication, redirect home.
	res.redirect('/');
});

Examples

Developers using the popular Express web framework can refer to an example as a starting point for their own web applications. The example shows how to authenticate users using Facebook. However, because both Facebook and Google use OAuth 2.0, the code is similar. Simply replace references to Facebook with corresponding references to Google.
