The error message “ResizeObserver loop limit exceeded” means that your application is stuck in an infinite loop while trying to recompute some layout measurements.

ResizeObserver API detects changes in the size of an element’s content box and is used by complex applications such as those dealing with layout management. However, in case it keeps attempting to recompute and resize indefinitely, this error message pops up.

Most of the time, this error is more of a warning and does not affect the functionality of your application. However, it shows up because there’s a potential performance issue linked to it.

To fix this issue, you need to optimize your ResizeObserver code and avoid infinite loops, such as resizing elements in the callback which triggers another observation call, ultimately leading to infinite loop. Here’s a pattern you could use to avoid this problem:

“`
let resizeObserver = new ResizeObserver((entries) => {
for (let entry of entries) {
// Ensure the observed box is being resized constantly
if (entry.contentRect.width !== this.previousWidth
|| entry.contentRect.height !== this.previousHeight) {
// Carry out the resize action here – this code will not be run if
// the box’s dimensions remain the same as they were before

this.previousWidth = entry.contentRect.width;
this.previousHeight = entry.contentRect.height;
}
}
});
“`

In this code, it checks whether the dimensions of the box (either its width or height) have actually changed from what they were previously before performing the resize action, which prevents the infinite loop.

If the error continues to show up, there might be other scripts or third-party libraries in your code which could force the page layout to constantly change and trigger resize observations constantly. These scripts need to be identified and optimized.
