How to call a specific function before and after every fetch api request and response
I want to call a function during sending a request and after receiving response with every fetch() function using Vanilla JS. I saw that jquery ajax is providing some kind of $.ajaxsetup for doing this but I want to do it with Vanilla JS. Thanks in advance.
fetch doesn't have a feature like that. You could write a wrapper function though:
const myFetch = async (...args) => {
do_before();
const result = await fetch(...args);
do_after();
return result;
}
and then call that function instead of accessing fetch directly.
