I'm not talking about what is inside the useEffect in this particular case. I'm talking about the comment where you said empty dependency array will cause the effect to run in each render.

a useEffect runs each render when there is no dependency array is provided, not when there is an empty dependency array.

eka waradi nm react docs th waradi wenna one
https://react.dev/reference/react/useEffect#my-effect-runs-after-every-re-render

PS: If you tried to say that useEffect runs after each render even if an empty array is provided because of the logic inside useEffect, no worries. I just wanted to correct that comment as in the way it was written, it was perceived as a generalized comment.

මේකේ මූ කරන්නේ pdftron lib එකෙන් PDF files edit කරල ඒක කොහෙටහරි upload කරන එකක්... මේකෙ documentLoaded event එක trigger වෙනවා මුලදි & මේකෙදි

instance.UI.loadDocument(url, {extension: 'pdf'});

එතකොට කොහොමත් infinit loop තමා... හැබැයි ලූප් වෙන්නේ useEffect එක තියෙන component එක නෙමෙයි.. අර PDF එක තියෙන div එක... ඒක නිකන් JS වල document onload event එක ඇතුලට redirect function එකක් දැම්ම වගේ...

document retrieval part එකයි upload part එකයි useEffect එකෙන් එලියට ගලවල අරන් වෙනම ලියන්න ඕනේ..
