oauth-express

express-oauth

Add oauth client to your express server.

require the handlers and add them to your app.

handlers = require("express-oauth").handlers;

app.get('/auth/:provider', handlers.auth_provider_redirect);
app.get('/auth_callback/:provider', handlers.auth_callback);

You have to rerun your app with environment variables set:

OAUTH_REDIRECT_URL=http://domain-where-user-ends-up.com

So, maybe you have a page at http://localhost:8080 that wants to initiate OAUTH. The app running express-oauth may be at http://localhost:3000. You can use Oauth.io to initiate the auth with a popup - on http://localhost:8080:

OAuth.setOAuthdURL("http://localhost:3000")
OAuth.popup "github", (err, provider_data) ->
  access_token = provider_data.access_token

So, to run the express-oauth-enabled app on localhost:3000, you set the OAUTH_REDIRECT_URL to http://localhost:8080.

$ OAUTH_REDIRECT_URL=http://localhost:8080 nodemon server
Listening on port 3000

To use Github as the Oauth provider, you must also set the env variables, GITHUB_CLIENT_SECRET and GITHUB_CLIENT_ID (more providers coming soon).

Once we have the access_token and user data back from github, we emit an event that can be used to write to a db or have other side effects:

githubee = require("express-oauth").emitters.github
githubee.on 'complete', (data) ->
  db.write data.access_token, JSON.stringify(data.user_data)
