Vibe coding might be very hard - presentation

Building apps with AI is easier than ever and ever.

Doing it right? Still hard. It still requires knowledge and skills. But it’s easier than ever.

I put together a few practical tips for builders of new era.

Presentation

Keep API keys secret: Never hardcode keys in your app. Store secrets in environment variables or a free secrets manager to keep them safe. 1Password has some interesting features that are worth looking at!
Scan for vulnerabilities: Run a free Snyk scan (or enable GitHub Dependabot) to catch known security flaws in your code/dependencies early.
HTTPS everywhere: Always serve your app over HTTPS. Tools like Let’s Encrypt give free SSL certificates!
Lock your accounts: Enable 2-factor authentication on critical services (GitHub, cloud platforms, AI tools etc.). It’s free and prevents easy hacks on your accounts.
Set hard budget limits in all tools that charge for usage, like Chat-GPT. It might save you a lot of money!

Stop emailing zip files: Use Git for version control. It tracks every change so you can undo mistakes and never lose code again.
Free cloud backup: Push your code to GitHub or GitLab (free private repos) for safekeeping. If your laptop crashes, your code stays safe in the cloud.
Branch for safety: Experiment on a new branch instead of directly on main. Merge when it’s working, or delete it if not — no harm done to your main codebase.
GitHub Desktop helps: If the command line scares you, use the free GitHub Desktop app. It’s a point-and-click way to commit, push, and pull code – no terminal needed. Most coding editors have already build-in graphic interface for GIT.
Automate testing & deploys: Use GitHub Actions (free) to run checks or deploy your app on every push. Automation catches issues early and saves manual effort.

One-click hosting: Deploy your app on platforms like Railway Vercel. You just push code and chill.
No server? No problem: Firebase offers hosting, database, and auth with a free plan. Great way to get backend features without managing any servers.
Static site hero: Use Netlify, Vercel, or GitHub Pages for a static website or frontend app. They’re free – just connect your repo or drop your files to go live.
Continuous deploy: Link your code repo to your host (Railway, Vercel, etc.). Every time you push changes, the service auto-deploys your app. No more manual uploads!
Serverless functions: Need a bit of backend logic? Use cloud functions on a free tier (Firebase Functions, Vercel, Netlify, AWS, GCP, Azure). Your code runs on demand.

Split project into smaller tasks – Easier to manage, debug, and parallelize.
Write detailed documentation first – Force model/agent to follow it. Include goals, edge cases, and examples.
Monitor token and compute costs – Large files or loops can explode usage. If your app is using AI, then integrate your app with LangSmith or a similar observability tool.
Limit workspace scope – Restrict to relevant directories or files only for each task.
Define clear input/output format – Avoid ambiguity. Keep structure strict and predictable. Define all details and rules in each prompt.
Use isolated test cases – Help the model validate logic step-by-step. Ask the model to create tests according to BDD (Behavior Driven Development).
Fail fast, retry smart – Catch issues early, and design fallback or retry logic.
