Did you know that Johannes Hoppe, a GDE that has been a part of the community for more than 10 years, maintains angular-cli-ghpages?

This tool makes it incredibly easy to deploy Angular apps to GitHub Pages or CloudFlare Pages directly from the Angular CLI. Give it a try

Years active in the community - 10+ years Favourite Angular feature - The Angular CLI is my favorite feature. It empowers developers to get started quickly, optimizes the development workflow, and ensures consistency across teams. Website - https://angular.schule/blog Fun fact - I co-wrote the German Angular Book in all its 4 editions, and I still find myself learning new things about Angular every day! Also, my coffee addiction is supercharging my Angular coding sessions.
