Fetch API Core Differences

  • **JSON Body Stringification**: Standard browser fetch doesn't automatically serialize request bodies to JSON; you must run `JSON.stringify(data)` and include correct headers.
  • **Non-throwing Bad Statuses**: The Promise returned from fetch() **does not reject** on HTTP error status (like 404 or 500). To properly catch errors, you must manually assert `if (!response.ok)`.
  • **Multi-part Requests**: When appending multipart file payloads using `FormData`, do not set the `Content-Type` header manually; the browser must append boundary parameters.
