2.16.0

Patch Changes

When using Lazy Route Discovery (future.v3_lazyRouteDiscovery), Remix will now detect manifest version mismatches after a new deploy and trigger a document reload to sync up any active client sessions with the newly deployed version (#10498)
- On navigations to undiscovered routes, this mismatch will trigger a document reload of the destination path
- On fetcher calls to undiscovered routes, this mismatch will trigger a document reload of the current path
- While performing Eager Route Discovery on rendered <Link> components, mismatches will result in a no-op

Single Fetch: Re-export interface Future through @remix-run/node/@remix-run/cloudflare/@remix-run/deno packages so that pnpm doesn't complain about @remix-run/server-runtime not being a dependency (#9982)

2.12.0

Patch Changes

Single Fetch: Do not try to encode a turbo-stream body into 304 responses (#9941)
Single Fetch: fix revalidation behavior bugs (#9938)
- With Single Fetch, existing routes revalidate by default
- This means requests do not need special query params for granular route revalidations out of the box - i.e., GET /a/b/c.data
- There are two conditions that will trigger granular revalidation:
  - If a route opts out of revalidation via shouldRevalidate, it will be excluded from the single fetch call
  - If a route defines a clientLoader then it will be excluded from the single fetch call and if you call serverLoader() from your clientLoader, that will make a separarte HTTP call for just that route loader - i.e., GET /a/b/c.data?_routes=routes/a for a clientLoader in routes/a.tsx
- When one or more routes are excluded from the single fetch call, the remaining routes that have loaders are included as query params:
  - For example, if A was excluded, and the root route and routes/b had a loader but routes/c did not, the single fetch request would be GET /a/b/c.data?_routes=root,routes/a
Remove hydration URL check that was originally added for React 17 hydration issues and we no longer support React 17 (#9890)
- Reverts the logic originally added in Remix v1.18.0 via https://github.com/remix-run/remix/pull/6409
- This was added to resolve an issue that could arise when doing quick back/forward history navigations while JS was loading which would cause a mismatch between the server matches and client matches: https://github.com/remix-run/remix/issues/1757
- This specific hydration issue would then cause this React v17 only looping issue: https://github.com/remix-run/remix/issues/1678
- The URL comparison that we added in 1.18.0 turned out to be subject to false positives of it's own which could also put the user in looping scenarios
- Remix v2 upgraded it's minimal React version to v18 which eliminated the v17 hydration error loop
- React v18 handles this hydration error like any other error and does not result in a loop
- So we can remove our check and thus avoid the false-positive scenarios in which it may also trigger a loop
Single Fetch: Improved typesafety (#9893)

If you were already using previously released unstable single-fetch types:
- Remove "@remix-run/react/future/single-fetch.d.ts" override from tsconfig.json > compilerOptions > types
- Remove defineLoader, defineAction, defineClientLoader, defineClientAction helpers from your route modules
- Replace UIMatch_SingleFetch type helper with UIMatch
- Replace MetaArgs_SingleFetch type helper with MetaArgs
Then you are ready for the new typesafety setup:
```
// vite.config.ts

declare module "@remix-run/server-runtime" {
  interface Future {
    unstable_singleFetch: true; // 👈 enable _types_ for single-fetch
  }
}

export default defineConfig({
  plugins: [
    remix({
      future: {
        unstable_singleFetch: true, // 👈 enable single-fetch
      },
    }),
  ],
});
```

2.11.1

Patch Changes

Revert #9695, stop infinite reload (a7cffe57)

2.11.0

Minor Changes

Single Fetch: Add a new unstable_data() API as a replacement for json/defer when custom status/headers are needed (#9769)
Add a new replace(url, init?) alternative to redirect(url, init?) that performs a history.replaceState instead of a history.pushState on client-side navigation redirects (#9764)
Rename future.unstable_fogOfWar to future.unstable_lazyRouteDiscovery for clarity (#9763)
Single Fetch: Remove responseStub in favor of headers (#9769)
- Background
  - The original Single Fetch approach was based on an assumption that an eventual middleware implementation would require something like ResponseStub so users could mutate status/headers in middleware before/after handlers as well as during handlers
  - We wanted to align how headers got merged between document and data requests
  - So we made document requests also use ResponseStub and removed the usage of headers in Single Fetch
  - The realization/alignment between Michael and Ryan on the recent roadmap planning made us realize that the original assumption was incorrect
  - middleware won't need a stub - users can just mutate the Response they get from await next() directly
  - With that gone, and still wanting to align how headers get merged, it makes more sense to stick with the current headers API and apply that to Single Fetch and avoid introducing a totally new thing in RepsonseStub (that always felt a bit awkward to work with anyway)
- With this change:
  - You are encouraged to stop returning Response instances in favor of returning raw data from loaders and actions:
    - ~~return json({ data: whatever });~~
    - return { data: whatever };
  - In most cases, you can remove your json() and defer() calls in favor of returning raw data if they weren't setting custom status/headers
    - We will be removing both json and defer in the next major version, but both should still work in Single Fetch in v2 to allow for incremental adoption of the new behavior
  - If you need custom status/headers:
    - We've added a new unstable_data({...}, responseInit) utility that will let you send back status/headers alongside your raw data without having to encode it into a Response
  - The headers() function will let you control header merging for both document and data requests

2.9.1

No significant changes to this package were made in this release. See the repo CHANGELOG.md for an overview of all changes in v2.9.1.

2.9.0

Minor Changes

New future.unstable_singleFetch flag (#8773)
- Naked objects returned from loaders/actions are no longer automatically converted to JSON responses. They'll be streamed as-is via turbo-stream so Date's will become Date through useLoaderData()
- You can return naked objects with Promise's without needing to use defer() - including nested Promise's
  - If you need to return a custom status code or custom response headers, you can still use the defer utility
- <RemixServer abortDelay> is no longer used. Instead, you should export const streamTimeout from entry.server.tsx and the remix server runtime will use that as the delay to abort the streamed response
  - If you export your own streamTimeout, you should decouple that from aborting the react renderToPipeableStream. You should always ensure that react is aborted afer the stream is aborted so that abort rejections can be flushed down
- Actions no longer automatically revalidate on 4xx/5xx responses (via RR future.unstable_skipActionErrorRevalidation flag) - you can return a 2xx to opt-into revalidation or use shouldRevalidate
Add ResponseStub header interface for single fetch and deprecate the headers export (#9142)
- The headers export is no longer used when single fetch is enabled
- loader/action functions now receive a mutable response parameter
  - type ResponseStub = { status: numbers | undefined, headers: Headers }
- To alter the status of a response, set the status field directly
  - response.status = 201
- To set headers on the Response, you may use:
  - response.headers.set
  - response.headers.append
  - response.headers.delete
- Each loader/actionreceives it's own unique response instance so you cannot see what other loader/action functions have set (which would be subject to race conditions)
- If all status codes are unset or have values <200, the deepest status code will be used for the HTTP response
- If any status codes are set to a value >=300, the highest >=300 value will be used for the HTTP Response
- Remix tracks header operations and will replay them in order (action if present, then loaders top-down) after all handlers have completed on a fresh Headers instance that will be applied to the HTTP Response
  - headers.set on any child handler will overwrite values from parent handlers
  - headers.append can be used to set the same header from both a parent and child handler
  - headers.delete can be used to delete a value set by a parent handler, but not a value set from a child handler
- Because single fetch supports naked object returns, and you no longer need to return a Response instance to set status/headers, the json/redirect/redirectDocument/defer utilities are considered deprecated when using Single Fetch
- You may still continue returning normal Response instances and they'll apply status codes in the same way, and will apply all headers via headers.set - overwriting any same-named header values from parents
  - If you need to append, you will need to switch from returning a Response instance to using the new response parameter

2.5.1

No significant changes to this package were made in this release. See the repo CHANGELOG.md for an overview of all changes in v2.5.1.

2.5.0

Minor Changes

Updated cookie dependency to 0.6.0 to inherit support for the Partitioned attribute (#8375)
Add unstable support for "SPA Mode" (#8457)

You can opt into SPA Mode by setting unstable_ssr: false in your Remix Vite plugin config:
```
// vite.config.ts
import { unstable_vitePlugin as remix } from "@remix-run/dev";
import { defineConfig } from "vite";

export default defineConfig({
  plugins: [remix({ unstable_ssr: false })],
});
```
Development in SPA Mode is just like a normal Remix app, and still uses the Remix dev server for HMR/HDR:
```
remix vite:dev
```
Building in SPA Mode will generate an index.html file in your client assets directory:
```
remix vite:build
```
To run your SPA, you serve your client assets directory via an HTTP server:
```
npx http-server build/client
```
For more information, please refer to the SPA Mode docs.

2.4.1

Patch Changes

Add optional error to ServerRuntimeMetaArgs type to align with MetaArgs (#8238)

2.4.0

Minor Changes

Add support for clientLoader/clientAction/HydrateFallback route exports (RFC). (#8173)

Remix now supports loaders/actions that run on the client (in addition to, or instead of the loader/action that runs on the server). While we still recommend server loaders/actions for the majority of your data needs in a Remix app - these provide some levers you can pull for more advanced use-cases such as:
- Leveraging a data source local to the browser (i.e., localStorage)
- Managing a client-side cache of server data (like IndexedDB)
- Bypassing the Remix server in a BFF setup and hitting your API directly from the browser
- Migrating a React Router SPA to a Remix application
By default, clientLoader will not run on hydration, and will only run on subsequent client side navigations.

If you wish to run your client loader on hydration, you can set clientLoader.hydrate=true to force Remix to execute it on initial page load. Keep in mind that Remix will still SSR your route component so you should ensure that there is no new required data being added by your clientLoader.

If your clientLoader needs to run on hydration and adds data you require to render the route component, you can export a HydrateFallback component that will render during SSR, and then your route component will not render until the clientLoader has executed on hydration.

clientAction is simpler than clientLoader because it has no hydration use-cases. clientAction will only run on client-side navigations.

For more information, please refer to the clientLoader and clientAction documentation.
Deprecate DataFunctionArgs in favor of LoaderFunctionArgs/ActionFunctionArgs. This is aimed at keeping the types aligned across server/client loaders/actions now that clientLoader/clientActon functions have serverLoader/serverAction parameters which differentiate ClientLoaderFunctionArgs/ClientActionFunctionArgs. (#8173)
Add a new future.v3_relativeSplatPath flag to implement a breaking bug fix to relative routing when inside a splat route. For more information, please see the React Router 6.21.0 Release Notes and the useResolvedPath docs. (#8216)

Remove deprecated REMIX_DEV_HTTP_ORIGIN env var - use REMIX_DEV_ORIGIN instead (#6963)

Removed support for "magic exports" from the remix package. This package can be removed from your package.json and you should update all imports to use the source @remix-run/* packages: (#6895)

- import type { ActionArgs } from "remix";
- import { json, useLoaderData } from "remix";
+ import type { ActionArgs } from "@remix-run/node";

Patch Changes

Export proper ErrorResponse type for usage alongside isRouteErrorResponse (#7244)
Fix destroySession for sessions using a maxAge cookie (#7252)
- The data in the cookie was always properly destroyed but when using maxAge, the cookie itself wasn't deleted because Max-Age takes precedence over Expires in the cookie spec
Ensure maxAge/expires options passed to commitSession take precedence over the original cookie.expires value (#6598, #7374)
Fix handleError method to correctly receive ErrorResponse instances on ?_data and resource route requests (#7211)
- It now receives the ErrorResponse instance the same way a document request would
- Users can leverage isRouteErrorResponse to detect these error instances and log accordingly
Update createMemorySessionStorage to use an internal hash value instead of an integer for the session id (#7227)
Fix false-positive resource route classification on document requests for routes that only export an ErrorBoundary (#7155)

1.18.1

Patch Changes

Fix reload loops in scenarios where CDNs ignore search params (#6707)
Avoid circular references and infinite recursion in types (#6736)
- "Pretty" or simplified Typescript types are evaluated by eagerly resolving types. For complex types with circular references, this can cause TS to recurse infinitely.
- To fix this, pretty types are reverted as a built-in DX feature of useLoaderData, useActionData, etc...
Updated dependencies:
- @remix-run/router@1.7.1

1.18.0

Minor Changes

stabilize v2 dev server (#6615)

Patch Changes

Fix typing issues when using React 17 stemming from @remix/server-runtime including @types/react as a devDependency when it doesn't actually do anything React-specific and was just re-exporting ComponentType in values such as CatchBoundaryComponent/ErrorBoundaryComponent/V2_ErrorBoundaryComponent. These types are more correctly exported from @remix-run/react which is React-aware so that is the correct place to be importing those types from. In order to avoid breaking existing builds, the types in @remix/server-runtime have been loosened to any and @deprecated warnings have been added informing users to switch to the corresponding types in @remix-run/react. (#5713)
fix(types): better tuple serialization types (#6616)
Move @types/cookie to dependencies since we re-export types from there (#5713)

1.17.1

No significant changes to this package were made in this release. See the releases page on GitHub for an overview of all changes in v1.17.1.

1.17.0

Minor Changes

Add errorHeaders parameter to the leaf headers() function to expose headers from thrown responses that bubble up to ancestor route boundaries. If the throwing route contains the boundary, then errorHeaders will be the same object as loaderHeaders/actionHeaders for that route. (#6425, #6475)

Add optional handleError export for custom server-side error processing. This is a new optional export from your entry.server.tsx that will be called with any encountered error on the Remix server (loader, action, or render error) (#6495, #6524):

// entry.server.tsx
export function handleError(
  error: unknown,
  { request, params, context }: DataFunctionArgs
): void {
  if (error instanceof Error) {
    sendErrorToBugReportingService(error);
    console.error(formatError(error));
  } else {
    const unknownError = new Error("Unknown Server Error");
    sendErrorToBugReportingService(unknownError);
    console.error(unknownError);
  }
}

Force Typescript to simplify type produced by Serialize. (#6449)

As a result, the following types and functions have simplified return types:

SerializeFrom
useLoaderData
useActionData
useFetcher

type Data = { hello: string; when: Date };

// BEFORE
type Unsimplified = SerializeFrom<Data>;
//   ^? SerializeObject<UndefinedToOptional<{ hello: string; when: Date }>>

// AFTER
type Simplified = SerializeFrom<Data>;
//   ^? { hello: string; when: string }

Added a new future.v2_headers future flag to opt into automatic inheriting of ancestor route headers functions so you do not need to export a headers function from every possible leaf route if you don't wish to. (#6431)
Reuse dev server port for WebSocket (Live Reload,HMR,HDR) (#6476)

As a result the webSocketPort/--websocket-port option has been obsoleted. Additionally, scheme/host/port options for the dev server have been renamed.

Available options are:

| Option | flag | config | default | | ---------- | ------------------ | ---------------- | --------------------------------- | | Command | -c / --command | command | remix-serve <server build path> | | Scheme | --scheme | scheme | http | | Host | --host | host | localhost | | Port | --port | port | Dynamically chosen open port | | No restart | --no-restart | restart: false | restart: true |

Note that scheme/host/port options are for the dev server, not your app server. You probably don't need to use scheme/host/port option if you aren't configuring networking (e.g. for Docker or SSL).

Patch Changes

Properly handle thrown ErrorResponse instances inside resource routes (#6320)

Add HeadersArgs type to be consistent with loaders/actions/meta and allows for using a function declaration in addition to an arrow function expression (#6247)

import type { HeadersArgs } from "@remix-run/node"; // or cloudflare/deno

export function headers({ loaderHeaders }: HeadersArgs) {
  return {
    "x-my-custom-thing": loaderHeaders.get("x-my-custom-thing") || "fallback",
  };
}

Minor Changes

Enable support for CSS Modules, Vanilla Extract and CSS side-effect imports (#6046)

These CSS bundling features were previously only available via future.unstable_cssModules, future.unstable_vanillaExtract and future.unstable_cssSideEffectImports options in remix.config.js, but they have now been stabilized.

In order to use these features, check out our guide to CSS bundling in your project.
Stabilize built-in PostCSS support via the new postcss option in remix.config.js. As a result, the future.unstable_postcss option has also been deprecated. (#5960)

The postcss option is false by default, but when set to true will enable processing of all CSS files using PostCSS if postcss.config.js is present.

If you followed the original PostCSS setup guide for Remix, you may have a folder structure that looks like this, separating your source files from its processed output:
```
.
├── app
│   └── styles (processed files)
│       ├── app.css
│       └── routes
│           └── index.css
└── styles (source files)
    ├── app.css
    └── routes
        └── index.css
```
After you've enabled the new postcss option, you can delete the processed files from app/styles folder and move your source files from styles to app/styles:
```
.
├── app
│   └── styles (source files)
│       ├── app.css
│       └── routes
│           └── index.css
```
You should then remove app/styles from your .gitignore file since it now contains source files rather than processed output.

You can then update your package.json scripts to remove any usage of postcss since Remix handles this automatically. For example, if you had followed the original setup guide:
```
{
  "scripts": {
-    "dev:css": "postcss styles --base styles --dir app/styles -w",
-    "build:css": "postcss styles --base styles --dir app/styles --env production",
-    "dev": "concurrently \"npm run dev:css\" \"remix dev\""
+    "dev": "remix dev"
  }
}
```
Stabilize built-in Tailwind support via the new tailwind option in remix.config.js. As a result, the future.unstable_tailwind option has also been deprecated. (#5960)

The tailwind option is false by default, but when set to true will enable built-in support for Tailwind functions and directives in your CSS files if tailwindcss is installed.

If you followed the original Tailwind setup guide for Remix and want to make use of this feature, you should first delete the generated app/tailwind.css.

Then, if you have a styles/tailwind.css file, you should move it to app/tailwind.css.
```
rm app/tailwind.css
mv styles/tailwind.css app/tailwind.css
```
Otherwise, if you don't already have an app/tailwind.css file, you should create one with the following contents:
```
@tailwind base;
@tailwind components;
@tailwind utilities;
```
You should then remove /app/tailwind.css from your .gitignore file since it now contains source code rather than processed output.

You can then update your package.json scripts to remove any usage of tailwindcss since Remix handles this automatically. For example, if you had followed the original setup guide:
```
{
  // ...
  "scripts": {
-    "build": "run-s \"build:*\"",
+    "build": "remix build",
-    "build:css": "npm run generate:css -- --minify",
-    "build:remix": "remix build",
-    "dev": "run-p \"dev:*\"",
+    "dev": "remix dev",
-    "dev:css": "npm run generate:css -- --watch",
-    "dev:remix": "remix dev",
-    "generate:css": "npx tailwindcss -o ./app/tailwind.css",
    "start": "remix-serve build"
  }
  // ...
}
```
The Remix dev server spins up your app server as a managed subprocess. (#6133) This keeps your development environment as close to production as possible. It also means that the Remix dev server is compatible with any app server.

By default, the dev server will use the Remix App Server, but you opt to use your own app server by specifying the command to run it via the -c/--command flag:
```
remix dev # uses `remix-serve <serve build path>` as the app server
remix dev -c "node ./server.js" # uses your custom app server at `./server.js`
```
The dev server will:
- force NODE_ENV=development and warn you if it was previously set to something else
- rebuild your app whenever your Remix app code changes
- restart your app server whenever rebuilds succeed
- handle live reload and HMR + Hot Data Revalidation
App server coordination

In order to manage your app server, the dev server needs to be told what server build is currently being used by your app server. This works by having the app server send a "I'm ready!" message with the Remix server build hash as the payload.

This is handled automatically in Remix App Server and is set up for you via calls to broadcastDevReady or logDevReady in the official Remix templates.

If you are not using Remix App Server and your server doesn't call broadcastDevReady, you'll need to call it in your app server after it is up and running. For example, in an Express server:
```
// server.js
// <other imports>
import { broadcastDevReady } from "@remix-run/node";

// Path to Remix's server build directory ('build/' by default)
const BUILD_DIR = path.join(process.cwd(), "build");

// <code setting up your express server>

app.listen(3000, () => {
  const build = require(BUILD_DIR);
  console.log("Ready: http://localhost:" + port);

  // in development, call `broadcastDevReady` _after_ your server is up and running
  if (process.env.NODE_ENV === "development") {
    broadcastDevReady(build);
  }
});
```
Options

Options priority order is: 1. flags, 2. config, 3. defaults.

| Option | flag | config | default | | -------------- | ------------------ | ---------------- | --------------------------------- | | Command | -c / --command | command | remix-serve <server build path> | | HTTP(S) scheme | --http-scheme | httpScheme | http | | HTTP(S) host | --http-host | httpHost | localhost | | HTTP(S) port | --http-port | httpPort | Dynamically chosen open port | | Websocket port | --websocket-port | websocketPort | Dynamically chosen open port | | No restart | --no-restart | restart: false | restart: true |

🚨 The --http-* flags are only used for internal dev server <-> app server communication. Your app will run on your app server's normal URL.

To set unstable_dev configuration, replace unstable_dev: true with unstable_dev: { <options> }. For example, to set the HTTP(S) port statically:
```
// remix.config.js
module.exports = {
  future: {
    unstable_dev: {
      httpPort: 8001,
    },
  },
};
```
SSL and custom hosts

You should only need to use the --http-* flags and --websocket-port flag if you need fine-grain control of what scheme/host/port for the dev server. If you are setting up SSL or Docker networking, these are the flags you'll want to use.

🚨 Remix will not set up SSL and custom host for you. The --http-scheme and --http-host flag are for you to tell Remix how you've set things up. It is your task to set up SSL certificates and host files if you want those features.

--no-restart and require cache purging

If you want to manage server changes yourself, you can use the --no-restart flag to tell the dev server to refrain from restarting your app server when builds succeed:
```
remix dev -c "node ./server.js" --no-restart
```
For example, you could purge the require cache of your app server to keep it running while picking up server changes. If you do so, you should watch the server build path (build/ by default) for changes and only purge the require cache when changes are detected.

🚨 If you use --no-restart, it is your responsibility to call broadcastDevReady when your app server has picked up server changes. For example, with chokidar:
```
// server.dev.js
// eslint-disable-next-line no-restricted-globals
const BUILD_PATH = path.resolve(__dirname, "build");

const watcher = chokidar.watch(BUILD_PATH);

watcher.on("change", () => {
  // 1. purge require cache
  purgeRequireCache();
  // 2. load updated server build
  const build = require(BUILD_PATH);
  // 3. tell dev server that this app server is now ready
  broadcastDevReady(build);
});
```

Patch Changes

add logDevReady as replacement for platforms that can't initialize async I/O outside of the request response lifecycle. (#6204)
better type discrimination when unwrapping loader return types (#5516)
pass AppLoadContext to handleRequest (#5836)
Updated dependencies:
- react-router-dom@6.11.0
- @remix-run/router@1.6.0

1.15.0

Minor Changes

We have made a few changes to the API for route module meta functions when using the future.v2_meta flag. These changes are only breaking for users who have opted in. (#5746)
- V2_HtmlMetaDescriptor has been renamed to V2_MetaDescriptor
- The meta function's arguments have been simplified
  - parentsData has been removed, as each route's loader data is available on the data property of its respective match object
```
// before
export function meta({ parentsData }) {
  return [{ title: parentsData["routes/some-route"].title }];
}
// after
export function meta({ matches }) {
  return [
    {
      title: matches.find((match) => match.id === "routes/some-route")
        .data.title,
    },
  ];
}
```
  - The route property on route matches has been removed, as relevant match data is attached directly to the match object
```
// before
export function meta({ matches }) {
  const rootModule = matches.find((match) => match.route.id === "root");
}
// after
export function meta({ matches }) {
  const rootModule = matches.find((match) => match.id === "root");
}
```
- Added support for generating <script type='application/ld+json' /> and meta-related <link /> tags to document head via the route meta function when using the v2_meta future flag
Added a new future.v2_normalizeFormMethod flag to normalize the exposed useNavigation().formMethod as an uppercase HTTP method to align with the previous useTransition behavior as well as the fetch() behavior of normalizing to uppercase HTTP methods. (#5815)
- When future.v2_normalizeFormMethod === false,
  - useNavigation().formMethod is lowercase
  - useFetcher().formMethod is uppercase
- When future.v2_normalizeFormMethod === true:
  - useNavigation().formMethod is uppercase
  - useFetcher().formMethod is uppercase
Added deprecation warning for CatchBoundary in favor of future.v2_errorBoundary (#5718)
Added experimental support for Vanilla Extract caching, which can be enabled by setting future.unstable_vanillaExtract: { cache: true } in remix.config. This is considered experimental due to the use of a brand new Vanilla Extract compiler under the hood. In order to use this feature, you must be using at least v1.10.0 of @vanilla-extract/css. (#5735)

1.11.1

No significant changes to this package were made in this release. See the releases page on GitHub for an overview of all changes in v1.11.1.

1.11.0

Minor Changes

Added support for Vanilla Extract via the unstable_vanillaExtract future flag. IMPORTANT: Features marked with unstable are … unstable. While we're confident in the use cases they solve, the API and implementation may change without a major version bump. (#5040)
Add support for CSS side-effect imports via the unstable_cssSideEffectImports future flag. IMPORTANT: Features marked with unstable are … unstable. While we're confident in the use cases they solve, the API and implementation may change without a major version bump. (#4919)
Add support for CSS Modules via the unstable_cssModules future flag. IMPORTANT: Features marked with unstable are … unstable. While we're confident in the use cases they solve, the API and implementation may change without a major version bump. (#4852)

Patch Changes

Added the v2_errorBoundary future flag to opt into the next version of Remix's ErrorBoundary behavior. This removes the separate CatchBoundary and ErrorBoundary and consolidates them into a single ErrorBoundary, following the logic used by errorElement in React Router. You can then use isRouteErrorResponse to differentiate between thrown Response/Error instances. (#4918)

// Current (Remix v1 default)
import { useCatch } from "@remix-run/react";

export function CatchBoundary() {
  const caught = useCatch();
  return (
    <p>
      {caught.status} {caught.data}
    </p>
  );
}

export function ErrorBoundary({ error }) {
  return <p>{error.message}</p>;
}

// Using future.v2_errorBoundary
import { isRouteErrorResponse, useRouteError } from "@remix-run/react";

export function ErrorBoundary() {
  const error = useRouteError();

  return isRouteErrorResponse(error) ? (
    <p>
      {error.status} {error.data}
    </p>
  ) : (
    <p>{error.message}</p>
  );
}

Introduces the defer() API from @remix-run/router with support for server-rendering and HTTP streaming. This utility allows you to defer values returned from loader functions by returning promises instead of resolved values. This has been refered to as "sending a promise over the wire". (#4920)

1.8.1

No significant changes to this package were made in this release. See the releases page on GitHub for an overview of all changes in v1.8.1.

1.8.0

Minor Changes

We have been busy at work Layering Remix on top of React Router 6.4 and are excited to be releasing step 1 in this process that consists of performing all server-side data fetches/mutations through the new framework agnostic @remix-run/router. Server- and client-side rendering are still done the same as before, and will be updated in subsequent releases. (#4612)
Importing functions and types from the remix package is deprecated, and all (#3284) exported modules will be removed in the next major release. For more details, see the release notes for 1.4.0 where these changes were first announced.
Added support for a new route meta API to handle arrays of tags instead of an object. For details, check out the RFC. (#4610)

Patch Changes

Properly categorize internal framework-thrown error Responses as error boundary errors (#4385)

Previously there was some ambiguity around "thrown Responses go to the CatchBoundary". The CatchBoundary exists to give the user a place to handle non-happy path code flows such that they can throw Response instances from their own code and handle them in a CatchBoundary. However, there are a handful of framework-internal errors that make sense to have a non-500 status code, and the fact that these were being thrown as Response instances was causing them to go into the CatchBoundary, even though they were not user-thrown.

With this change, anything thrown by the framework itself (Error or Response) will go to the ErrorBoundary, and any user-thrown Response instances will go to the CatchBoundary. There is one exception to this rule, which is that framework-detected 404's will continue to go to the CatchBoundary since users should have one single location to handle 404 displays.

The primary affected use cases are scenarios such as:
- HTTP OPTIONS requests (405 Unsupported Method )
- GET requests to routes without loaders (400 Bad Request)
- POST requests to routes without actions (405 Method Not Allowed)
- Missing route id in _data parameters (403 Forbidden)
- Non-matching route id included in _data parameters (403 Forbidden)

1.7.1

Patch Changes

Properly locked the dependency on react-router-dom to version 6.3.0 (#4203)

1.7.0

Minor Changes

We've added a new type: SerializeFrom. This is used to infer the (#4013) JSON-serialized return type of loaders and actions.
MetaFunction type can now infer data and parentsData types from route loaders (#4022)

Patch Changes

Improved performance for data serialization at runtime (#3889)

1.6.8

Patch Changes

We've added type safety for load context. AppLoadContext is now an an interface mapping string to unknown, allowing users to extend it via module augmentation: (#1876)
```
declare module "@remix-run/server-runtime" {
  interface AppLoadContext {
    // add custom properties here!
  }
}
```

1.6.7

No significant changes to this package were made in this release. See the releases page on GitHub for an overview of all changes in v1.6.7.

1.6.6

No significant changes to this package were made in this release. See the releases page on GitHub for an overview of all changes in v1.6.6.

1.6.5

Patch Changes

We enhanced the type signatures of loader/action and useLoaderData/useActionData to make it possible to infer the data type from return type of its related server function.

To enable this feature, you will need to use the LoaderArgs type from your Remix runtime package instead of typing the function directly:
```
- import type { LoaderFunction } from "@remix-run/[runtime]";
+ import type { LoaderArgs } from "@remix-run/[runtime]";

- export const loader: LoaderFunction = async (args) => {
-   return json<LoaderData>(data);
- }
+ export async function loader(args: LoaderArgs) {
+   return json(data);
+ }
```
Then you can infer the loader data by using typeof loader as the type variable in useLoaderData:
```
- let data = useLoaderData() as LoaderData;
+ let data = useLoaderData<typeof loader>();
```
The API above is exactly the same for your route action and useActionData via the ActionArgs type.

With this change you no longer need to manually define a LoaderData type (huge time and typo saver!), and we serialize all values so that useLoaderData can't return types that are impossible over the network, such as Date objects or functions.

See the discussions in #1254 and #3276 for more context.
