How will timeout be determined when using fetch? [duplicate]

Question

I have read a few questions and answers and found that we can not set timeout for a fetch request. In that case, what will determine the timeout of a fetch request? What if the server never responds to the fetch request? Is it expected that the fetch request is alive forever till server responds or client kills it?

Answer 1

There isn't a magic number that's specific to the Fetch API. As a matter of fact, it's not even mentioned in the specification. However, what you should think about is the browser in which you're using. That may play a role in how long a given request is allowed to live (see this)

If you need to enforce a timeout, then I would suggest wrapping your fetch call within a custom timeout wrapper (example here)
