A CRUD Express backend with JWT sign-up and log-in. Working in TDD with Jest and Supertest. It has file uploading. With a hexagonal/clean architecture, the domain is completely separate. We can change whether it's using MongoDb or in memory arrays with just a .env variable. I can also switch Express for something else without having to rewrite the domain.
The project needs a .env file at the root, with a MONGO_URL and a CONTEXT variable. Either CONTEXT=dev to work exclusively with in memory data (which has no persistence) or any other string to enable the MongoDB.
To start the server, run npm run start. It will serve on port 3000.
From there you can run a postman or use a front-end like this one:

Just run npm run start and, on your browser, navigate to http://localhost:4200/.
