Discord OAuth2 with ExpressJs and Axios

This is a sample app on how you can implement discord oauth2 on the backend.

Clean Version

There is a clean version of this code in which all the comments from index.js has been removed which you can clone if you want to work with the code and not want to clean up the comments manually.

To clone just that branch, you can use degit. By using degit, it won't clone the git history and the other branches, so it will be much cleaner and quicker.

npx degit KrishGarg/OAuth2-Discord-ExpressJs#clean
