Minimal MEAN: All About the Stack

By Doguhan Uluca

Minimal MEAN: All About the Stack

It can be daunting to pick the right stack to deliver your idea to the cloud. Without realizing, you can introduce one too many "sandbag of complexity" between you and something you can release. It is possible to do full-stack development with a consistent set of tools and best practices using the same language, JavaScript. No more to context switching between front-end and back-end languages, libraries, and tools. However, it is important to not to dig yourself into a hole. My easy to learn and use stack 'Minimal MEAN' will get you started and deployed on the cloud over a lazy weekend, without requiring a MongoDB install, while leveraging the latest tools like async/await with Typescript, Angular and Node.
