javascript - fetch resolves even if 404? - Stack OverflowIf you want a 404 to be a rejection, you could code that yourself: fetch('notExists').then(function(response) {. if (!response.ok) {. // make the promise be rejected if we didn't get a 2xx response. throw new Error("Not 2xx response", {cause: response}); } else {. // got the desired response.
I'm playing around with fetch, and I noticed that only Chrome displays an error when a resource I am fetching doesn't exist (aka a 404): Both Edge and Firefox don't do that, and 404 errors using fetch don't seem to trigger a NetworkError to have my catch error handler to get notified.

Utiliser l'API Fetch - Les API Web | MDN - MDN Web DocsL'API Fetch (en anglais, le verbe fetch signifie récupérer) fournit une interface JavaScript pour accéder et manipuler certaines parties du protocole, comme les requêtes et les réponses. Elle fournit également une méthode globale fetch () qui permet un accès pratique aux ressources récupérées de façon asynchrone sur le réseau.
La fonction fetch() renvoie une promesse. Si celle-ci réussit, la fonction passée au premier bloc .then() contiendra la réponse renvoyée par le serveur. Dans cette fonction : On vérifie que le serveur n'a pas renvoyé d'erreur (comme 404 Not Found). Si c'est le cas, on lève l'erreur. On appelle json() sur la réponse.
