    Tests with jest and mongodb

    Includes much more code, other than the actual implementation, creating the extra mocks. It's clear in the complete example that mocks are more lines of code than the actual UserService.

  • mongodb-memory-server

    Spinning up mongod in memory for fast tests. If you run tests in parallel this lib helps to spin up dedicated mongodb servers for every test file in MacOS, *nix, Windows or CI environments (in most cases with zero-config).

    The final method tries to combine both methods, 1 and 2. It uses an external package MongoDB In-Memory Server for our MongoDB.

  • Appwrite

    Appwrite - The Open Source Firebase alternative introduces iOS support . Appwrite is an open source backend server that helps you build native iOS applications much faster with realtime APIs for authentication, databases, files storage, cloud functions and much more!

  • Docker Compose

    Define and run multi-container applications with Docker

    Here comes Docker and Docker Compose. I am not going to spend much time explaining Docker, but if you want I can write a separate blog about it.
