You don’t need Redux.
You don’t need 18 folders.
You don’t need a backend (yet).
Sometimes, the cleanest app is also the most teachable.
So we built a fully functional Todo app in just 15 lines using React + useState.
🧠 No build config.
⚡ No state libraries.
📦 No component explosion.
Just a clear example of:
- React’s simplicity
- The power of useState()
- Why less can be more
Yes, it adds todos.
Yes, it deletes them.
And yes, you’ll want to copy/paste it for your next demo or interview test.
At @Techlusion, we coach dev teams to:
- Strip away unnecessary complexity
- Fetch from client → call backend → backend securely accesses the key
- Design for clarity first, then complexity (if you need it)
Because bloat doesn’t ship faster. Simplicity does.
Over to You:
What’s the smallest project you’ve built that actually worked?
Ever challenged yourself to ship under 50 lines?
