Make sure that you use for only one time running, or pass some specific values from component scope to the second argument. Why is the cleanup function from `useEffect` called on every render? It has various modes such as a tree editor, a code editor, and a plain text editor. UseEffect runs infinite loop despite no change in dependencies JSON Editor is a web-based tool to view, edit, format, and validate JSON. I posted this short note from React because I saw some people make the mistake when they use the Effect Hook and this will slow your application down and cause some unexpected bugs. This isn’t handled as a special case - it follows directly from how the dependencies array always works. This tells React that your effect doesn’t depend on any values from props or state, so it never needs to re-run. If you want to run an effect and clean it up only once (on mount and unmount), you can pass an empty array ( ) as a second argument. I did this because I just want this hook run only one time to create the JSON Editor. The reason I have to use the Effect Hook is to make sure that the piece of code inside the hook will run from on the client side since window is undefined on the server side.įor the Effect Hook above, I passed second arguments as.
