This is a MEAN stack skeleton to quickly get you started with your MEAN app project. The Node.js backend is built in TypeScript, the database used is MySQL and the Angular front-end is inpired from the free Core UI project. You can change to PostgreSQL or anything else as you need.
It has all the necessary main components already created for you (classes, configs, routes, etc), all you have to do is to just look at the samples and build from that. Saving you a lot of time
