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

Vite: Cloudflare Proxy as a Vite plugin (#8749)

This is a breaking change for projects relying on Cloudflare support from the unstable Vite plugin

The Cloudflare preset (unstable_cloudflarePreset) as been removed and replaced with a new Vite plugin:
```
 import {
    unstable_vitePlugin as remix,
-   unstable_cloudflarePreset as cloudflare,
+   cloudflareDevProxyVitePlugin as remixCloudflareDevProxy,
  } from "@remix-run/dev";
  import { defineConfig } from "vite";

  export default defineConfig({
    plugins: [
+     remixCloudflareDevProxy(),
+     remix(),
-     remix({
-       presets: [cloudflare()],
-     }),
    ],
-   ssr: {
-     resolve: {
-       externalConditions: ["workerd", "worker"],
-     },
-   },
  });
```
remixCloudflareDevProxy must come before the remix plugin so that it can override Vite's dev server middleware to be compatible with Cloudflare's proxied environment.

Because it is a Vite plugin, remixCloudflareDevProxy can set ssr.resolve.externalConditions to be workerd-compatible for you.

remixCloudflareDevProxy accepts a getLoadContext function that replaces the old getRemixDevLoadContext. If you were using a nightly version that required getBindingsProxy or getPlatformProxy, that is no longer required. Any options you were passing to getBindingsProxy or getPlatformProxy should now be passed to remixCloudflareDevProxy instead.

This API also better aligns with future plans to support Cloudflare with a framework-agnostic Vite plugin that makes use of Vite's (experimental) Runtime API.
Vite: Stabilize the Remix Vite plugin, Cloudflare preset, and all related types by removing all unstable_ / Unstable_ prefixes. (#8713)

While this is a breaking change for existing Remix Vite plugin consumers, now that the plugin has stabilized, there will no longer be any breaking changes outside of a major release. Thank you to all of our early adopters and community contributors for helping us get here! 🙏
Vite: Stabilize "SPA Mode" by renaming the Remix vite plugin config from unstable_ssr -> ssr (#8692)

Vite: Enable use of vite preview to preview Remix SPA applications (#8624)
- In the SPA template, npm run start has been renamed to npm run preview which uses vite preview instead of a standalone HTTP server such as http-server or serv-cli
Vite: Remove the ability to pass publicPath as an option to the Remix vite plugin (#8145)
- ⚠️ This is a breaking change for projects using the unstable Vite plugin with a publicPath
- This is already handled in Vite via the base config so we now set the Remix publicPath from the Vite base config
Vite: Fix issue where client route file requests fail if search params have been parsed and serialized before reaching the Remix Vite plugin (#8740)

Minor Changes

Add future.v3_throwAbortReason flag to throw request.signal.reason when a request is aborted instead of an Error such as new Error("query() call aborted: GET /path") (#8251)

Patch Changes

Vite: Add manifest option to Vite plugin to enable writing a .remix/manifest.json file to the build directory (#8575)

This is a breaking change for consumers of the Vite plugin's "server bundles" feature.

The build/server/bundles.json file has been superseded by the more general build/.remix/manifest.json. While the old server bundles manifest was always written to disk when generating server bundles, the build manifest file must be explicitly enabled via the manifest option.
Vite: Provide Unstable_ServerBundlesFunction and Unstable_VitePluginConfig types (#8654)
Vite: add --sourcemapClient and --sourcemapServer flags to remix vite:build (#8613)
- --sourcemapClient
- --sourcemapClient=inline
- --sourcemapClient=hidden
- --sourcemapServer
- --sourcemapServer=inline
- --sourcemapServer=hidden
See https://vitejs.dev/config/build-options.html#build-sourcemap
Vite: Validate IDs returned from the serverBundles function to ensure they only contain alphanumeric characters, hyphens and underscores (#8598)
Vite: fix "could not fast refresh" false alarm (#8580)

HMR is already functioning correctly but was incorrectly logging that it "could not fast refresh" on internal client routes. Now internal client routes correctly register Remix exports like meta for fast refresh, which removes the false alarm.
Vite: Cloudflare Pages support (#8531)

To get started with Cloudflare, you can use the [unstable-vite-cloudflare][template-vite-cloudflare] template:
```
npx create-remix@latest --template remix-run/remix/templates/unstable-vite-cloudflare
```
Or read the new docs at Future > Vite > Cloudflare and Future > Vite > Migrating > Migrating Cloudflare Functions.
Vite: Remove undocumented backwards compatibility layer for Vite v4 (#8581)
Vite: rely on Vite plugin ordering (#8627)

This is a breaking change for projects using the unstable Vite plugin.

The Remix plugin expects to process JavaScript or TypeScript files, so any transpilation from other languages must be done first. For example, that means putting the MDX plugin before the Remix plugin:
```
  import mdx from "@mdx-js/rollup";
  import { unstable_vitePlugin as remix } from "@remix-run/dev";
  import { defineConfig } from "vite";

  export default defineConfig({
    plugins: [
+     mdx(),
      remix()
-     mdx(),
    ],
  });
```
Previously, the Remix plugin misused enforce: "post" from Vite's plugin API to ensure that it ran last. However, this caused other unforeseen issues. Instead, we now rely on standard Vite semantics for plugin ordering.

The official Vite React SWC plugin also relies on plugin ordering for MDX.
Vite: Add presets option to ease integration with different platforms and tools. (#8514)
Vite: Remove interop with <LiveReload />, rely on <Scripts /> instead (#8636)

This is a breaking change for projects using the unstable Vite plugin.

Vite provides a robust client-side runtime for development features like HMR, making the <LiveReload /> component obsolete.

In fact, having a separate dev scripts component was causing issues with script execution order. To work around this, the Remix Vite plugin used to override <LiveReload /> into a bespoke implementation that was compatible with Vite.

Instead of all this indirection, now the Remix Vite plugin instructs the <Scripts /> component to automatically include Vite's client-side runtime and other dev-only scripts.
```
  import {
-   LiveReload,
    Outlet,
    Scripts,
  }

  export default function App() {
    return (
      <html>
        <head>
        </head>
        <body>
          <Outlet />
          <Scripts />
-         <LiveReload />
        </body>
      </html>
    )
  }
```
Vite: Add buildEnd hook (#8620)
Vite: add dev load context option to Cloudflare preset (#8649)
Vite: Add mode field into generated server build (#8539)
Vite: Only write Vite manifest files if build.manifest is enabled within the Vite config (#8599)

This is a breaking change for consumers of Vite's manifest.json files.

To explicitly enable generation of Vite manifest files, you must set build.manifest to true in your Vite config.
```
export default defineConfig({
  build: { manifest: true },
  // ...
});
```
Vite: reduce network calls for route modules during HMR (#8591)
Vite: Add new buildDirectory option with a default value of "build". This replaces the old assetsBuildDirectory and serverBuildDirectory options which defaulted to "build/client" and "build/server" respectively. (#8575)

This is a breaking change for consumers of the Vite plugin that were using the assetsBuildDirectory and serverBuildDirectory options.

The Remix Vite plugin now builds into a single directory containing client and server directories. If you've customized your build output directories, you'll need to migrate to the new buildDirectory option, e.g.
```
import { unstable_vitePlugin as remix } from "@remix-run/dev";
import { defineConfig } from "vite";

export default defineConfig({
  plugins: [
    remix({
-      serverBuildDirectory: "dist/server",
-      assetsBuildDirectory: "dist/client",
+      buildDirectory: "dist",
    })
  ],
});
```
Vite: Remove unstable prefix from serverBundles option. (#8596)
Vite: Write Vite manifest files to build/.vite directory rather than being nested within build/client and build/server directories. (#8599)

This is a breaking change for consumers of Vite's manifest.json files.

Vite manifest files are now written to the Remix build directory. Since all Vite manifests are now in the same directory, they're no longer named manifest.json. Instead, they're named build/.vite/client-manifest.json and build/.vite/server-manifest.json, or build/.vite/server-{BUNDLE_ID}-manifest.json when using server bundles.

2.5.0

Minor Changes

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.

Add unstable_serverBundles option to Vite plugin to support splitting server code into multiple request handlers. (#8332)

This is an advanced feature designed for hosting provider integrations. When compiling your app into multiple server bundles, there will need to be a custom routing layer in front of your app directing requests to the correct bundle. This feature is currently unstable and only designed to gather early feedback.

Example usage:

import { unstable_vitePlugin as remix } from "@remix-run/dev";
import { defineConfig } from "vite";

export default defineConfig({
  plugins: [
    remix({
      unstable_serverBundles: ({ branch }) => {
        const isAuthenticatedRoute = branch.some(
          (route) => route.id === "routes/_authenticated"
        );

        return isAuthenticatedRoute ? "authenticated" : "unauthenticated";
      },
    }),
  ],
});

Vite: Error messages when .server files are referenced by client (#8267)
- Previously, referencing a .server module from client code resulted in an error message like:
  - The requested module '/app/models/answer.server.ts' does not provide an export named 'isDateType'
- This was confusing because answer.server.ts does provide the isDateType export, but Remix was replacing .server modules with empty modules (export {}) for the client build
- Now, Remix explicitly fails at compile time when a .server module is referenced from client code and includes dedicated error messages depending on whether the import occurs in a route or a non-route module
- The error messages also include links to relevant documentation
Remove unstable_viteServerBuildModuleId in favor of manually referencing virtual module name "virtual:remix/server-build". (#8264)

This is a breaking change for projects using the unstable Vite plugin with a custom server.

This change was made to avoid issues where @remix-run/dev could be inadvertently required in your server's production dependencies.

Instead, you should manually write the virtual module name "virtual:remix/server-build" when calling ssrLoadModule in development.
```
-import { unstable_viteServerBuildModuleId } from "@remix-run/dev";

// ...

app.all(
  "*",
  createRequestHandler({
    build: vite
-      ? () => vite.ssrLoadModule(unstable_viteServerBuildModuleId)
+      ? () => vite.ssrLoadModule("virtual:remix/server-build")
      : await import("./build/server/index.js"),
  })
);
```
Vite: Fix errors for non-existent index.html importer (#8353)
Add vite:dev and vite:build commands to the Remix CLI. (#8211)

In order to handle upcoming Remix features where your plugin options can impact the number of Vite builds required, you should now run your Vite dev and build processes via the Remix CLI.
```
{
  "scripts": {
-    "dev": "vite dev",
-    "build": "vite build && vite build --ssr"
+    "dev": "remix vite:dev",
+    "build": "remix vite:build"
  }
}
```
Vite: Preserve names for exports from .client modules (#8200)

Unlike .server modules, the main idea is not to prevent code from leaking into the server build since the client build is already public. Rather, the goal is to isolate the SSR render from client-only code. Routes need to import code from .client modules without compilation failing and then rely on runtime checks or otherwise ensure that execution only happens within a client-only context (e.g. event handlers, useEffect).

Replacing .client modules with empty modules would cause the build to fail as ESM named imports are statically analyzed. So instead, we preserve the named export but replace each exported value with undefined. That way, the import is valid at build time and standard runtime checks can be used to determine if the code is running on the server or client.

Minor Changes

Vite: exclude modules within .server directories from client build (#8154)
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.
Vite: Strict route exports (#8171)

With Vite, Remix gets stricter about which exports are allowed from your route modules. Previously, the Remix compiler would allow any export from routes. While this was convenient, it was also a common source of bugs that were hard to track down because they only surfaced at runtime.

For more, see https://remix.run/docs/en/main/future/vite#strict-route-exports
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 unstable_createViteServer and unstable_loadViteServerBuild which were only minimal wrappers around Vite's createServer and ssrLoadModule functions when using a custom server. (#8120)

This is a breaking change for projects using the unstable Vite plugin with a custom server.

Instead, we now provide unstable_viteServerBuildModuleId so that custom servers interact with Vite directly rather than via Remix APIs, for example:

-import {
-  unstable_createViteServer,
-  unstable_loadViteServerBuild,
-} from "@remix-run/dev";
+import { unstable_viteServerBuildModuleId } from "@remix-run/dev";

Creating the Vite server in middleware mode:

const vite =
  process.env.NODE_ENV === "production"
    ? undefined
-    : await unstable_createViteServer();
+    : await import("vite").then(({ createServer }) =>
+        createServer({
+          server: {
+            middlewareMode: true,
+          },
+        })
+      );

Loading the Vite server build in the request handler:

app.all(
  "*",
  createRequestHandler({
    build: vite
-      ? () => unstable_loadViteServerBuild(vite)
+      ? () => vite.ssrLoadModule(unstable_viteServerBuildModuleId)
      : await import("./build/server/index.js"),
  })
);

Rather, the goal is to isolate the SSR render from client-only code. Routes need to import code from .client modules without compilation failing and then rely on runtime checks to determine if the code is running on the server or client.

Replacing .client modules with empty modules would cause the build to fail as ESM named imports are statically analyzed. So instead, we preserve the named export but replace each exported value with an empty object. That way, the import is valid at build time and the standard runtime checks can be used to determine if then code is running on the server or client.

Remove automatic global Node polyfill installation from the built-in Vite dev server and instead allow explicit opt-in. (#8119)

This is a breaking change for projects using the unstable Vite plugin without a custom server.

If you're not using a custom server, you should call installGlobals in your Vite config instead.
```
import { unstable_vitePlugin as remix } from "@remix-run/dev";
+import { installGlobals } from "@remix-run/node";
import { defineConfig } from "vite";

+installGlobals();

export default defineConfig({

Vite: Errors at build-time when client imports .server default export (#8184)

Remix already stripped .server file code before ensuring that server code never makes it into the client. That results in errors when client code tries to import server code, which is exactly what we want! But those errors were happening at runtime for default imports. A better experience is to have those errors happen at build-time so that you guarantee that your users won't hit them.

Attach CSS from shared chunks to routes in Vite build (#7952)
fix(vite): Let Vite handle serving files outside of project root via /@fs (#7913)
- This fixes errors when using default client entry or server entry in a pnpm project where those files may be outside of the project root, but within the workspace root.
- By default, Vite prevents access to files outside the workspace root (when using workspaces) or outside of the project root (when not using workspaces) unless user explicitly opts into it via Vite's server.fs.allow.
Improve performance of LiveReload proxy in Vite dev (#7883)
fix(vite): deduplicate @remix-run/react (#7926)
- Pre-bundle Remix dependencies to avoid Remix router duplicates.
- Our remix-react-proxy plugin does not process default client and
- server entry files since those come from within node_modules.
- That means that before Vite pre-bundles dependencies (e.g. first time dev server is run) mismatching Remix routers cause Error: You must render this element inside a <Remix> element.

Major Changes

The create-remix CLI has been rewritten to feature a cleaner interface, Git repo initialization and optional remix.init script execution. The interactive template prompt and official Remix stack/template shorthands have also been removed so that community/third-party templates are now on a more equal footing. (#6887)
- The code for create-remix has been moved out of the Remix CLI since it's not intended for use within an existing Remix application
- This means that the remix create command is no longer available.
Enable built-in PostCSS and Tailwind support by default. (#6909)
- These tools are now automatically used within the Remix compiler if PostCSS and/or Tailwind configuration files are present in your project.
- If you have a custom PostCSS and/or Tailwind setup outside of Remix, you can disable these features in your remix.config.js via the postcss:false and/or tailwind:false flags
Drop React 17 support (#7121)
Require Node >=18.0.0 (#6939)
Compile server build to Node 18 (#7292)
- This allows features like top-level await to be used within a Remix app
Remove default Node.js polyfills - you must now opt-into polyfills via the serverNodeBuiltinsPolyfill and browserNodeBuiltinsPolyfill configs (#7269)
Remove v2_errorBoundary flag and CatchBoundary implementation (#6906)
Remove v2_normalizeFormMethod future flag - all formMethod values will be normalized in v2 (#6875)
Remove v2_routeConvention flag - the flat route file convention is now standard (#6969)
Remove v2_headers flag - it is now the default behavior to use the deepest headers function in the route tree (#6979)
The route meta API now defaults to the new "V2 Meta" API (#6958)
- Please refer to the (docs and Preparing for V2 guide for more information.
Default to serverModuleFormat: "esm" and update remix-serve to use dynamic import to support ESM and CJS build outputs (#6949)

Remove replace-remix-magic-imports codemod (#6899)
Remove deprecated --no-restart/restart cli args/flags - use --manual/manual instead (#6962)
Remove deprecated --scheme/scheme and --host/host cli args/flags - use REMIX_DEV_ORIGIN instead (#6962)
Promote the future.v2_dev flag in remix.config.js to a root level dev config (#7002)

Remove serverBuildDirectory config option ([#6897](https://github.com/remix-run/remix/pull/- Remove codemod command (#6918) 6897))

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";
+ import { json } from "@remix-run/node";
+ import { useLoaderData } from "@remix-run/react";

Minor Changes

Warn users about obsolete future flags in remix.config.js (#7048)
Detect built mode via build.mode (#6964)
- Prevents mode mismatch between built Remix server entry and user-land server
- Additionally, all runtimes (including non-Node runtimes) can use build.mode to determine if HMR should be performed
Support bun package manager (#7074)

The serverNodeBuiltinsPolyfill option (along with the newly added browserNodeBuiltinsPolyfill) now supports defining global polyfills in addition to module polyfills (#7269)

For example, to polyfill Node's Buffer global:

module.exports = {
  serverNodeBuiltinsPolyfill: {
    globals: {
      Buffer: true,
    },
    // You'll probably need to polyfill the "buffer" module
    // too since the global polyfill imports this:
    modules: {
      buffer: true,
    },
  },
};

Patch Changes

Fix importing of PNGs, SVGs, and other assets from packages in node_modules (#6813, #7182)
Decouple the @remix-run/dev package from the contents of the @remix-run/css-bundle package. (#6982)
- The contents of the @remix-run/css-bundle package are now entirely managed by the Remix compiler
- Even though it's still recommended that your Remix dependencies all share the same version, this change ensures that there are no runtime errors when upgrading @remix-run/dev without upgrading @remix-run/css-bundle
Allow non-development modes for remix watch (#7117)
Stop remix dev when esbuild is not running (#7158)

Do not interpret JSX in .ts files (#7306)

While JSX is supported in .js files for compatibility with existing apps and libraries, .ts files should not contain JSX. By not interpreting .ts files as JSX, .ts files can contain single-argument type generics without needing a comma to disambiguate from JSX:

// this works in .ts files
const id = <T>(x: T) => x;
//          ^ single-argument type generic

// this doesn't work in .tsx files
const id = <T,>(x: T) => x;
//          ^ is this a JSX element? or a single-argument type generic?

// this works in .tsx files
const id = <T,>(x: T) => x;
//           ^ comma: this is a generic, not a JSX element
const component = <h1>hello</h1>;
//                   ^ no comma: this is a JSX element

Enhance obsolete flag warning for future.v2_dev if it was an object, and prompt users to lift it to the root dev config (#7427)
Allow decorators in app code (#7176)
Allow JSX in .js files during HMR (#7112)
Kill app server when remix dev terminates (#7280)
Support dependencies that import polyfill packages for Node built-ins via a trailing slash (e.g. importing the buffer package with var Buffer = require('buffer/').Buffer as recommended in their README) (#7198)
- These imports were previously marked as external
- This meant that they were left as dynamic imports in the client bundle and would throw a runtime error in the browser (e.g. Dynamic require of "buffer/" is not supported)
Surface errors when PostCSS config is invalid (#7391)

Metafiles can be uploaded to https://esbuild.github.io/analyze/ for analysis.

Add serverNodeBuiltinsPolyfill config option. In remix.config.js you can now disable polyfills of Node.js built-in modules for non-Node.js server platforms, or opt into a subset of polyfills. (#6814, #6859, #6877)

// Disable all polyfills
exports.serverNodeBuiltinsPolyfill = { modules: {} };

// Enable specific polyfills
exports.serverNodeBuiltinsPolyfill = {
  modules: {
    crypto: true, // Provide a JSPM polyfill
    fs: "empty", // Provide an empty polyfill
  },
};

Minor Changes

built-in tls support (#6483)

New options:

--tls-key / tlsKey: TLS key
--tls-cert / tlsCert: TLS Certificate

If both TLS options are set, scheme defaults to https

Example

Install mkcert and create a local CA:

brew install mkcert
mkcert -install

Then make sure you inform node about your CA certs:

export NODE_EXTRA_CA_CERTS="$(mkcert -CAROOT)/rootCA.pem"

👆 You'll probably want to put that env var in your scripts or .bashrc/.zshrc

Now create key.pem and cert.pem:

mkcert -key-file key.pem -cert-file cert.pem localhost

See mkcert docs for more details.

Finally, pass in the paths to the key and cert via flags:

remix dev --tls-key=key.pem --tls-cert=cert.pem

or via config:

module.exports = {
  future: {
    unstable_dev: {
      tlsKey: "key.pem",
      tlsCert: "cert.pem",
    },
  },
};

That's all that's needed to set up the Remix Dev Server with TLS.

🚨 Make sure to update your app server for TLS as well.

For example, with express:

import fs from "node:fs";
import https from "node:https";

import express from "express";

const app = express();

// ...code setting up your express app...

const appServer = https.createServer(
  {
    key: fs.readFileSync("key.pem"),
    cert: fs.readFileSync("cert.pem"),
  },
  app
);

appServer.listen(3000, () => {
  console.log("Ready on https://localhost:3000");
});

Known limitations

remix-serve does not yet support TLS. That means this only works for custom app server using the -c flag for now.

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

Add caching to PostCSS for regular stylesheets (#6505)
Fix warnings when importing CSS files with future.unstable_dev enabled (#6506)
Fix Tailwind performance issue when postcss.config.js contains plugins: { tailwindcss: {} } and remix.config.js contains both tailwind: true and postcss: true. (#6468)

Note that this was not an issue when the plugin function had been explicitly called, i.e. plugins: [tailwindcss()]. Remix avoids adding the Tailwind plugin to PostCSS if it's already present but we were failing to detect when the plugin function hadn't been called — either because the plugin function itself had been passed, i.e. plugins: [require('tailwindcss')], or the plugin config object syntax had been used, i.e. plugins: { tailwindcss: {} }.
Faster server export removal for routes when unstable_dev is enabled. (#6455)

Also, only render modulepreloads on SSR. Do not render modulepreloads when hydrated.

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",
  };
}

Fix route ranking bug with pathless layout route next to a sibling index route (#4421)

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
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);
});
