questionsHow to bundle an MEAN app for production
sa asked 2 years ago

I would like to track and update in this thread the latest best (and hopefully the simplest) method to bundle Angular (version 2, 4, …) for production on a live web server.
i used (MEAN) Mongo, Angular, Node Express to implement the project.
Please include the Angular version within answers so we can track better when it moves to later releases.
