• Optimizing React Builds with Vite

  30/03/25, 21:47

  Vite has become the standard build tool for modern React applications, replacing webpack in many projects.

  Key optimization strategies:

  1. Use import.meta.glob() for dynamic code-splitting
  2. Leverage @vitejs/plugin-react-swc for faster builds
  3. Configure vite.config.js with proper caching headers
  4. Implement lazy loading for all non-critical components

  Proper configuration can reduce bundle sizes by 40-60% and improve initial load times significantly.

• Build Code That Fails Fast

  28/03/25, 17:05

  Robust applications don’t hide errors—they expose them early.

  When building software:

  1. Validate inputs at system boundaries immediately
  2. Use strong typing (TypeScript, PropTypes) to catch errors at compile-time
  3. Write defensive code that checks assumptions
  4. Add assertions for conditions that must be true

  The sooner a problem surfaces, the easier and cheaper it is to fix.

• Rapidly Build MVPs, Test Before You Invest

  27/03/25, 12:06

  The fastest path to product validation is through a minimally viable product.

  Key principles to remember:

  1. Focus on core functionality only — no extra features.
  2. Use existing tools and templates when possible.
  3. Set a strict timeline (2-4 weeks maximum).
  4. Gather real user feedback early and often.

  The goal isn’t perfection but validation. Better to discover a fatal flaw with a 2-week MVP than after 6 months of development.

• Effective Node.js Debugging Techniques

  26/03/25, 04:10

  Debug your Node.js applications more efficiently with these approaches:

  1. Use —inspect-brk flag to pause execution at start for complex debugging.

  2. console.time() and console.timeEnd() help identify performance bottlenecks.

  3. Set NODE_DEBUG=module to see internal debug logs for core modules.

  4. Try util.debuglog() for conditional debugging output in production.

  Remember that proper logging is often more valuable than traditional debugging in distributed systems.

• Building a Fast MVP, Speed to Market

  25/03/25, 01:00

  The key to a successful MVP is focusing on core value while eliminating everything else.

  1. Define one primary problem your product solves.
  2. Choose familiar technology to reduce learning curve.
  3. Implement feature flags to hide incomplete work.
  4. Set a non-negotiable launch date and stick to it.

  Remember: An imperfect product in users’ hands is more valuable than a perfect product that never ships.

• Avoid Hidden Tech Debt in Your Codebase

  21/03/25, 00:59

  Tech debt can accumulate silently until it becomes overwhelming.

  Common sources of hidden debt:

  1. Duplicate code across components or services
  2. Missing documentation for critical business logic
  3. Skipped tests for “temporary” solutions
  4. Inconsistent error handling patterns

  Take time to regularly audit your code. What seems like a quick fix today often becomes tomorrow’s maintenance nightmare.

  Address tech debt deliberately and systematically, not just when it becomes problematic.

• Discipline in Software Development

  14/03/25, 01:03

  Discipline separates professionals from hobbyists in software development.

  To build a disciplined coding practice:

  1. Write tests first, not as an afterthought.
  2. Commit code daily, even if progress feels small.
  3. Maintain a consistent formatting standard across all projects.
  4. Document as you code — your future self will thank you.

  Excellence isn’t about inspiration. It’s about showing up consistently and following proven practices, even when motivation is low.

• Daily Code Review Habit

  14/03/25, 00:34

  Spending just 15 minutes daily reviewing code can dramatically improve your development skills.

  This practice helps you:

  1. Discover new patterns and techniques
  2. Identify common mistakes to avoid
  3. Better understand different approaches to solving problems
  4. Develop a critical eye for quality code

  Alternate between reviewing your own past code, open-source projects, and colleagues’ pull requests for maximum benefit.

• API Security Reminder

  13/03/25, 15:30

  APIs are the backbone of most applications, and security should be a top priority.

  1. Always use authentication (JWT, OAuth, API keys).
  2. Restrict CORS to trusted origins.
  3. Implement rate limiting to prevent abuse.
  4. Avoid sensitive data exposure in API responses.

  Security isn’t something to “add later” — it must be built-in from day one.

• Clean Code Rule

  13/03/25, 13:45

  If your function does more than one thing, it’s doing too much.
  If you need to add a comment to explain the logic, refactor the logic instead.

  Readable code reduces bugs. Simple, small functions improve maintainability.
  Write code for humans first, compilers second.
