55 Frontend Commandments: How to Stay Sane and Empower Yourself and Your Team

Introduction

Frontend is not just about code — it’s about people. In this talk, I shared 55 practical rules and insights that help make life easier, build teamwork, and grow as a developer.

Technical Principles

• There’s no perfect solution — production always has compromises.
• Next.js is a great choice thanks to SSR and SEO.
• A local admin panel is a must-have for debugging.
• Prettier and ESLint are your sword and shield for readable code.
• TypeScript helps with large projects but can get in the way in small ones.
• Tailwind is powerful but should be introduced carefully.
• Don’t touch working code without a good reason.
• Critical areas should be tested — no need to chase 100% coverage.
• Use the browser debugger.
• Browser extensions like TweakMock save hours.
• CodeSandbox and other sandboxes are great for experiments.

Team Collaboration

• Don’t blame past developers — they had their own context.
• Everyone deserves the right to make mistakes, ask questions, and receive support.
• Code reviews should help, not humiliate.
• Praise each other — it’s cheaper than motivational trainings.
• Help newcomers — you were one once.
• Say “I don’t know” — it saves hours.
• Before implementing a feature — double-check if it’s really needed.

Wisdom Teeth

• Don’t create idols.
• Developers are made, not born.
• Find good YouTube channels, including in English.
• Telegram isn’t just memes — it’s a skill booster.
• Teach others — it accelerates your own learning.
• Algorithms are not pain, they’re a gym for your brain.
• Even old projects have lessons to offer.
• A second monitor is a productivity hack.
• Don’t debug late at night — morning is wiser.
• Learn to explain things in business terms.
• Bring your laptop to meetings — solve problems on the spot.
• Love what you do — and luck will follow.

Conclusion

These 55 commandments are not law — they’re personal experience. You may adopt some and ignore others. But if even a couple help you — it was worth sharing.
