It's just a simple demo of how to make an OAuth2 client. In this specific example using GitHub.

Go to https://github.com/settings/applications/new and create a new OAuth application. Set the redirect callback URI to http://localhost:3000/api/v1/oauth2/github/callback. Copy the client ID and secret and put them in a .env file like so:

GITHUB_CLIENT_ID=YOUR_CLIENT_ID_HERE
GITHUB_CLIENT_SECRET=YOUR_CLIENT_SECRET_HERE

Build and run:

go build
./go-oauth2-client-short

Visit http://localhost:3000/api/v1/oauth2/github/redirect.
