This tutorial will show you how to integrate OAuth.io in your Node.js backend with a web front-end, using the server-side flow.
This tutorial uses both the OAuth.io front-end JavaScript SDK and the OAuth.io Node.js SDK.
This tutorial is based on a git repository that you can clone. You can follow the instructions by yourself or checkout each step of the tutorial, which are marked by tags in the git repository.
The tutorial contains the following steps :
Part 1 : server-side code
step-0 Getting the code (tagged step-0) step-1 Initializing OAuth.io server-side (tagged step-1) step-2 Adding a state token retrieval endpoint server-side (tagged step-2) step-3 Adding an authentication endpoint server-side (tagged step-3) step-4 Adding a request endpoint server-side
Part 2 : client-side code
step-5 Initializing OAuth.io client-side (tagged step-5) step-6 Adding a call to retrieve the state token (tagged step-6) step-7 Adding a call to authenticate the user (tagged step-7) step-8 Adding a call to the request endpoint to get user info (tagged step-8)
To be able to follow the tutorial, you need to be registered on oauth.io, and to have an application containing the provider Facebook, which must be set on server-side flow.
In this part you'll have to get the code from our Github repository, and fill up gaps in it to complete the tutorial.
The project in the repository is a really simple webserver written in Node.js with expressjs, that serves a single static page. That page must allow a user to login through Facebook, retrieve his basic information (name, email, avatar), and finally display them on the page.
Everything that doesn't concern OAuth.io's integr 5AF3 ation has already been written to gain time.
Step 0 : Getting the code
To checkout tutorial Github repository, just run the following commands :
$ git clone https://github.com/oauthio/sdk-node-tutorialTo get the beginning point and start coding, checkout the step-0 tag :
$ git checkout step-0Then you need to run npm install to install all the dependencies of the project.
$ npm installYou are now all set to follow the tutorial !
Step 1 : Initializing OAuth.io server-side
The first thing you need to do is to install the OAuth.io Node.js SDK and save it to the project's dependencies in the package.json :
$ npm install oauthio --saveOnce that's done, you can initialize the framework server-side.
