v6.14.0

Date: 2023-06-23

What's Changed

JSON/Text Submissions

6.14.0 adds support for JSON and Text submissions via useSubmit/fetcher.submit since it's not always convenient to have to serialize into FormData if you're working in a client-side SPA. To opt-into these encodings you just need to specify the proper formEncType:

Opt-into application/json encoding:

function Component() {
  let navigation = useNavigation();
  let submit = useSubmit();
  submit({ key: "value" }, { method: "post", encType: "application/json" });
  // navigation.formEncType => "application/json"
  // navigation.json        => { key: "value" }
}

async function action({ request }) {
  // request.headers.get("Content-Type") => "application/json"
  // await request.json()                => { key: "value" }
}

Opt-into text/plain encoding:

function Component() {
  let navigation = useNavigation();
  let submit = useSubmit();
  submit("Text submission", { method: "post", encType: "text/plain" });
  // navigation.formEncType => "text/plain"
  // navigation.text        => "Text submission"
}

async function action({ request }) {
  // request.headers.get("Content-Type") => "text/plain"
  // await request.text()                => "Text submission"
}

⚠️ Default Behavior Will Change in v7

Please note that to avoid a breaking change, the default behavior will still encode a simple key/value JSON object into a FormData instance:

function Component() {
  let navigation = useNavigation();
  let submit = useSubmit();
  submit({ key: "value" }, { method: "post" });
  // navigation.formEncType => "application/x-www-form-urlencoded"
  // navigation.formData    => FormData instance
}

async function action({ request }) {
  // request.headers.get("Content-Type") => "application/x-www-form-urlencoded"
  // await request.formData()            => FormData instance
}

This behavior will likely change in v7 so it's best to make any JSON object submissions explicit with formEncType: "application/x-www-form-urlencoded" or formEncType: "application/json" to ease your eventual v7 migration path.

Minor Changes

• Add support for application/json and text/plain encodings for useSubmit/fetcher.submit. To reflect these additional types, useNavigation/useFetcher now also contain navigation.json/navigation.text and fetcher.json/fetcher.text which include the json/text submission if applicable. (#10413)

Patch Changes

• When submitting a form from a submitter element, prefer the built-in new FormData(form, submitter) instead of the previous manual approach in modern browsers (those that support the new submitter parameter) (#9865)
  • For browsers that don't support it, we continue to just append the submit button's entry to the end, and we also add rudimentary support for type="image" buttons
  • If developers want full spec-compliant support for legacy browsers, they can use the formdata-submitter-polyfill
• Call window.history.pushState/replaceState before updating React Router state (instead of after) so that window.location matches useLocation during synchronous React 17 rendering (#10448)
  • ⚠️ Note: generally apps should not be relying on window.location and should always reference useLocation when possible, as window.location will not be in sync 100% of the time (due to popstate events, concurrent mode, etc.)
• Avoid calling shouldRevalidate for fetchers that have not yet completed a data load (#10623)
• Strip basename from the location provided to <ScrollRestoration getKey> to match the useLocation behavior (#10550)
• Strip basename from locations provided to unstable_useBlocker functions to match the useLocation behavior (#10573)
• Fix unstable_useBlocker key issues in StrictMode (#10573)
• Fix generatePath when passed a numeric 0 value parameter (#10612)
• Fix tsc --skipLibCheck:false issues on React 17 (#10622)
• Upgrade typescript to 5.1 (#10581)
