NodeJS-MongoDB Backend Stack Superpower for Business Applications

The goal of this course is to help you making the leap from legacy backend development (anything that's been around for roughly 10-plus years) to developing in a modern and popular stack that is super-powerful - when implemented correctly.

Right implementation approach is the key here. Someone making a feature-to-feature comparison between NodeJS-MongoDB stack and legacy marvels may say that there is no way the stack can handle anything worthwhile - it just seems too weak, like a toy. The truth is that in the Cloud Era, the power of stack is the power of its cloud-based deployment. Legacy marvels can run in the cloud (anything can!), but they don't take advantage of the cloud at the level the NodeJS-MongoDB stack does. Legacy stuff has been developed under concepts conflicting with how the cloud works. Legacy systems fight the cloud to do the work themselves. NodeJS-MongoDB fits in the cloud and lets the cloud do the hard lifting for it.

A core advantage of using NodeJS-MongoDB stack as the backend for a modern business application is its power-to-complexity ratio: you get an infinitely scalable, full-featured modern server at a low implementation and maintenance complexity. Keep-it-simple at its best.

Let's quickly define the components of the stack and the special things about them:

  • NodeJS: use of full processing capacity of the runtime environment. Unlike the legacy frameworks designed to micro-manage the backend server capacity, NodeJS is a single-threaded non-blocking process that uses as much CPU and memory as the operating system environment makes available to it. No tuning of the number of "workers" or "threads" - the scalability is handled at the machine level, which is exactly what the cloud systems do best: machine power is added when the load is high and reduced when the load is low

  • JavaScript and TypeScript: write only the necessary code. Modern JavaScript with asynchronous functions enables writing clear and easy to follow code. TypeScript is an important add-on bringing the order necessary when developing large applications with many components and objects to manage

  • Mongoose: simple and concise Data Access Layer. Mongoose makes MongoDB No-SQL data access API structured enough to reflect the data models in the program code, yet without isolating the code from data by some proprietary layer within the framework

  • MongoDB: fast, flexible, simple business data management system. MongoDB has excellent tools for efficient data storage and retrieval, yet it trusts the external systems to own the business side of the implementation: the data models, consistency and integrity, passing the key power into the business software developer's hands

So, is NodeJS-MongoDB the ultimate solution for business software backend development for many years to come? Absolutely not! If anything, the software lifecycles accelerate, and things like serverless technologies have already grown from concepts to running implementations. What does it mean for a developer? The survival and prosperity strategy should not be to sit around, buried in legacy, waiting for "what's next". The "next" always changes, so - get on and run with what's current, get ready for the next current, and then for next current, again and again.

This course shows you how easy it is to learn a technology that is relatively different from what an IT professional working with 20-th century tools is used to. The keys to succeed in this learning:

  • make sure to understand why things are done the way they are done. How is easy, why is smart. Don't skip over the why and ask for help if the course material falls short explaining things to your satisfaction
  • work to build a simple understanding of the concepts before diving into deep theory. This course does not cover the theory, it focuses on the practical use and value of the tools. If you are interested in the theory - be honest with yourself: are you in the right line of business? Sure, deep understanding of things helps a lot. However, realistically, the body of IT knowledge is growing too fast for a field developer having a chance to learn all the theory and still deliver the practice across these many evolving skills
  • work to improve the speed of your learning - from the moment you first read about a technology till completing your first meaningful implementation of it. Back to the point immediately above: in the flood of technologies it's about staying afloat, not about diving into the depths
