Barry vd. Heuvel has a post to his site sharing a step by step guide to setting up OAuth in a Lumen+AngularJS application via Socialite and Satellizer (an AngularJS library for OAuth and token based authentication).

In the last few weeks, Socialite was a popular topic to blog/tweet about. Coincidentally, I also needed Socialite for a project. But in my case, I wanted to use it in an Angular app, distributed using Cordova (Phonegap) as hybrid app on Android/iOS. There were some examples, but I couldn’t find much about it at the time. A few people asked to share my experience about it, so here it is!

He starts by linking to all of the tools you'll need to help get some background on them including a helpful guide to installing Satellizer. He then goes over the flow of the entire process, from the initial call from the AngularJS side to authenticate, through the backend Lumen/Socalite/Satellizer handling and then back out to the Javascript where the token is then stored. With this established, he gets into the implementation details starting with the Lumen code to make the API request to GitHub then working with the JWT tokens and responding back to the AngularJS frontend with the result.
