Code like a NASA engineer, even if you are a web developer

Here we are, peering into the abyss that is NASA's rather publicly available document on coding guidelines, a document that isn't just a set of instructions but a manifesto that challenges the very ethos of programming. These are people who hurl multi-million-dollar machinery beyond the stratosphere. These are the folks who engineer vehicles that traverse the void between celestial bodies with less drama than most of us can manage on a trip to the grocery store. And yes, we are absolutely steering clear of any mention of the Mariner 1 fiasco—because, let's face it, nobody wants their legacy to be defined by a hyphen that wasn't there.

It's fascinating, then, that the very first decree in this document is a bold proclamation of the potential uselessness of most coding guidelines. They often emerge from the ether of someone's personal preferences, and over time they solidify into these immutable laws that nobody really questions. Why do we indent code blocks one way over another? Why do brace styles become points of contention? NASA, in its empirical wisdom, brushes aside these pedestrian concerns with a gesture towards the utilitarian. Tool-based checks, it suggests, are impervious to the whims of the current coding sovereigns and cut straight to the heart of functionality without getting embroiled in stylistic quibbles.

Yet, in a universe filled with infinite complexities, NASA advocates for a simplicity that borders on the monastic: a small, clear set of coding rules. It's almost Zen, this approach.

In a cosmos cluttered with excessive information, the choice to minimize is both revolutionary and profoundly practical. These rules aren't merely meant to be followed; they're designed to be remembered and implemented without requiring a consultation with the oracle. If you want guidelines that people will actually remember and adhere to, keep them few and simple. They must be clear enough to be memorable and specific enough to be enforceable by software. Specificity is key—rules so precise and so targeted that a machine could verify them without breaking a digital sweat. This is coding minimalism as an art form, and its beauty lies in its clarity and utility.

Imagine applying this distilled wisdom to the seemingly mundane yet chaotic world of web development. Take, for instance, NASA's stern injunction against dynamic memory allocation post-initialization. In the terrestrial coding landscapes where memory leaks and performance degradation lurk in the shadows, pre-allocating resources could be likened to charting the course of a spacecraft with such precision that it flawlessly slips into the desired orbital path without the slightest hiccup.

Or consider the directive for control flow clarity. There's a certain elegance in constructing your code with the transparency and predictability of a well-drafted map of the known universe. Each function and loop in your Next.js clicking game becomes a carefully plotted trajectory, devoid of unnecessary recursions or bewildering jumps that could lead your program into the black holes of runtime errors.

And what of the mandate that functions should not sprawl endlessly across your screen, like some unchecked galaxy? Instead, they must be concise—each a self-contained unit of logic, as observable and understandable as a planet viewed through a high-powered telescope. Such a practice breeds not just cleaner code but fosters a modular architecture where components fit together with the snugness and precision of parts on the International Space Station.

Finally, the rule to compile with all warnings enabled and to treat these warnings as errors instills a discipline akin to the rigorous checks and balances one expects in spacecraft engineering. It cultivates a culture where code quality is paramount, where each warning light is addressed with the urgency of a hull breach on a lunar lander.

Thus, in embracing these principles from NASA's playbook, we elevate our coding practices from the merely functional to the sublime. We create software not just to perform but to perform reliably under the most extreme conditions imagined. And while the applications might be terrestrial, the philosophy is unarguably astronomical. It's a holistic approach that transforms coding from a mundane task into a pursuit of cosmic order. And in that pursuit, perhaps we can find not just better software but a greater appreciation for the underlying principles that drive both the vastness of space and the intricacies of our algorithms.

But how to translate this into my 9 to 5 web dev work? I shall have your back:

1. Simplicity in Control Flow:

   • Simplify your JavaScript or TypeScript functions.
   • Avoid unnecessary complications like deep nested conditions or complex chained promises.
   • Use async/await for better readability and error handling.

2. Fixed Upper-Bound Loops:

   • When iterating over data in your loops, always ensure bounds are clearly defined.
   • Avoid infinite loops or excessive processing that can crash browsers or servers.

3. Avoid Dynamic Memory Allocation Post-Initialization:

• Manage your application state efficiently, especially in single-page applications (SPAs)
• Utilize state management libraries like Redux or Context API effectively to handle state changes rather than relying on unpredictable and hard-to-track dynamic memory allocation.

4. Compact Functions:

• Keep your functions small and focused.
• Each function should perform one task or return one value
• This makes debugging easier and code reviews more efficient.
• If a function sprawls over dozens of lines, break it down into smaller, manageable pieces.

5. Assertive Programming:

• Use assertions liberally to check for unexpected states or values.
• In a web application, this might mean validating props in a React component or ensuring that variables contain expected values before proceeding with operations.

6. Minimal Scope of Data Objects:

• Declare variables and state as close as possible to where they are used.
• Limit global states unless absolutely necessary.
• This reduces side effects and makes state management clearer and more predictable.

7. Check Return Values and Validate Parameters:

• Always check API responses and function return values.
• Ensure that parameters passed to functions are valid.
• For example, when fetching data from a backend API, always check the response and error handle appropriately before trying to render data in the UI.

8. Restrict Preprocessor Use:

• Minimize the use of complex webpack configurations or Babel plugins that can obscure what your code is actually doing.
• Stick to simpler, more maintainable configurations that don't hide functionality.

9. Limit Pointer Use:

• Careful handling of references in JavaScript, particularly when dealing with the DOM or state management in React (like using refs).
• Be mindful of memory leaks especially in closures and hooks.

10. Compile with All Warnings Enabled:

• Use strict linter rules and compile settings in your development environment
• Tools like ESLint with strict rules can catch potential issues before they become problematic. - Treat console warnings as errors and fix them to maintain a clean, reliable codebase.

These adaptations not only enhance the robustness and reliability of web applications but also instill a disciplined approach to software development that mirrors the rigor of engineering for space exploration.

There you go, go launch some ships!
