If you’re like me, you might assume this code logs “error” when run—but it actually logs “ok”.

Fetch 500 Body
- Fetch intends to debut the new Freight 500, called CartConnect500, which can lug up to 500 kilograms (or 1,100 pounds) at the Modex 2020 trade show in Atlanta on March 9. A fully autonomous.
- Fetch and compare top online refinance mortgage rates and deals from qualified lenders. Get unbiased and expert advise on how to make informed decisions about your mortgage.
This expectation probably comes from years of jQuery development, as jQuery’s
ajax()
method invokes its fail
handler when the response contains a failed HTTP status code. For example, the code below logs “error” when run: Inspiration set for pages 3 3 download free.Why does fetch()
work this way?
Per MDN, the
fetch()
API only rejects a promise when a “network error is encountered, although this usually means permissions issues or similar.” Basically fetch()
will only reject a promise if the user is offline, or some unlikely networking error occurs, such a DNS lookup failure.The good is news is
fetch
provides a simple ok
flag that indicates whether an HTTP response’s status code is in the successful range or not. For instance the following code logs “Error: Internal Server Error(…)”:To keep this code DRY and reusable, you probably want to create a generic error handling function you can use for all of your
fetch()
calls. The following code refactors the error handling into a handleErrors()
function:Cleanmymac x 4 4 3 cr2 converter. For added fun you can use ES6 arrow functions to make the callback formatting a little less verbose:

Parting thoughts
Although I still don’t like
fetch()
’s lack of rejecting failed HTTP status codes, over time fetch()
’s behavior has grown on me—mostly because it gives me more control over how I handle individual problems. Plus, the composable nature of fetch()
makes it fairly trivial to manually handle errors without adding a bunch of verbose code.Overall I think it’s worth taking few minutes to play with
fetch()
, even if it’s just to see what you think. It’s certainly a far more readable alternative to XMLHttpRequest. If you happen to be building NativeScript apps, you might not know that you can use fetch()
today without any need for a polyfill or fallback. And something about using fetch()
to perform HTTP requests in native Android and iOS apps is just plain cool :)This article was updated on September 15th, 2015 to use a simpler
handleErrors()
function based on a comment from Jake Archibald.
