Fix “Too Many Re-renders” Error in React

~1 min read
⚡TL;DR

This error happens when your component keeps updating state inside render, causing an infinite loop.

You might see this error:

Too many re-renders. React limits the number of renders to prevent an infinite loop.

Common mistake:

JavaScript
const [count, setCount] = useState(0);setCount(count + 1); //inside component body

This runs on every render → infinite loop

Fix:

JavaScript
Use useEffect properly:

useEffect(() => { setCount(1);}, []);

Another safe pattern:

JavaScript
<button onClick={() => setCount(count + 1)}> Increment</button>

Pro Insight:

  • Never update state directly inside render
  • Always use useEffect or event handlers
  • Watch dependencies carefully
