I’m having trouble fixing a warning that says “React Hook useEffect has a missing dependency”. I’m a new developer and I’m using React Hooks for my project. I’m trying to update my app state every time the component mounts, so I’m using a useEffect hook. However, when I run my code, I get this warning in my console that says I’m missing a dependency. I researched online and saw that this warning means I should add a dependency to the useEffect hook, but I’m not sure how to do that.
Here’s a simplified version of my code:
import React, { useState, useEffect } from 'react';
function App() {
const [count, setCount] = useState(0);
useEffect(() => {
setCount(count + 1);
}, []);
return (
Count: {count}
);
}
This is the code I’m using and it’s producing the console warning. How can I fix this warning? What dependency do I need to add to the useEffect hook? How do I add this dependency to my code? I’m a bit lost and would really appreciate some help.
