Once register, you will get a client ID and a client secret.

Step two: get the code

First, clone the repo.

$ git clone https://github.com/json-HB/githun-oauth-login.git
$ cd node-oauth-demo

Second, modify the config.

• index.js: replace the values of the clientID and clientSecret variables.
• public/index.html: replace the values of the client_id variable.

Third, install the dependencies.

$ npm install

Step three: run the server

Now, run the server.

$ node index.js

Visit http://localhost:8080 in your browser, and click the link to login GitHub.
