In the React the JS application, at times we would get “Uncaught Error”Too many renders. React limit to a certain number of renders it can make to avoid an endless loop”. However, do you know why this happens. Actually, it’s due to a number of mistakes. Let’s try to comprehend what this error really means to us. It is a sign it is rendering at an infinity of times. There is a question that may pop up to mind: why our component is rendered in an infinite amount of time. This is due to the fact that the state of our component changes immediately as the component has been rendered. We know that if state changes, our component will render again. Thus, it creates an infinite loop.
When dose this error happen?
When adding a snackBar in order to display a message whenever a user signIn or not. SnackBar.jsx:, you might get the following issue:
Invariant Violation: Too many re-renders. React limits the number of renders to prevent an infinite loop.
at invariant (http://localhost:9000/bundle.js:34484:15)
at dispatchAction (http://localhost:9000/bundle.js:47879:44)
The issue is that in SnackbarContentWrapper. Should you use the useState
hooks in order to change the state of the snackBar or use a class and a componentShouldUpdate
in order to not render multiple times? To answer this question, follow these suggestion below to catch it up.
How To Solve The Error: “Invariant Violation: Too many re-renders. React limits the number of renders to prevent an infinite loop”?
Approach 1:
The issue is that in SnackbarContentWrapper, you must utilize the example below:
<IconButton
key="close"
aria-label="Close"
color="inherit"
className={classes.close}
onClick={() => onClose}
>
It’s only a matter of currying handleClose in SingInContainer:
const handleClose = () => (reason) => {
if (reason === 'clickaway') {
return;
}
setSnackBarState(false)
};
Approach 2:
In the onClick, you should link an event. The click function should also be notified of the event. Consider the following instance:
export default function Component(props) {
function clickEvent (event, variable){
console.log(variable);
}
return (
<div>
<IconButton
key="close"
aria-label="Close"
color="inherit"
onClick={e => clickEvent(e, 10)}
>
</div>
)
}
Approach 3:
Before invoking your handle method, you must include an event like this:
function ExampleContainer() {
handleClose = () => {
}
return (
<SnackBar
open={open}
handleClose={() => handleClose}
variant={variant}
message={message}
/>
<SignInForm/>
)
}
