Release Notes

webpack/webpack-dev-server (webpack-dev-server)

v6.1.0

Compare Source

Minor Changes

• Run as a plugin from the top-level plugins of a multi-configuration, serving every configuration from one server. (by @​alexander-akait in #​5765)

• Fix client progress modes, socket URL credentials, overlay and progress lifecycles, server startup error handling and local IP lookup; export BaseServer. (by @​alexander-akait in #​5739)

• The browser client, the error overlay and both transports now come from webpack-dev-middleware, so this package has no client code of its own. Every option keeps its name and meaning, allowedHosts and the origin checks still apply here, and this server's { type } messages are still sent next to the middleware's, so React Refresh keeps working. client/index.js, client/socket.js and client/clients/WebSocketClient.js still resolve while the client's internal files are gone, and the console wording, the overlay and the progress indicator are now the middleware's. client.webSocketTransport: "sse" adds Server-Sent Events, a universal build now runs in Node without the client throwing, and sendMessage(), getClientEntry() and getClientHotEntry() still work, a subclass's overrides included, but are deprecated. (by @​alexander-akait in #​5750)

Patch Changes

• Keep hot and live reload working after a cancelled "Leave site?" dialog. (by @​alexander-akait in #​5744)

• Keep the overlay for a runtime error thrown while the page is still loading. (by @​alexander-akait in #​5745)

• Validate the Host and Origin headers and enforce same-origin checks on WebSocket upgrade requests handled by proxies with ws: true. This prevents cross-origin pages from connecting to proxied WebSocket services through the development server. (by @​UlisesGascon in cb1534a)

• Validate options with a precompiled schema to cut ~115ms from startup. (by @​alexander-akait in #​5746)

• Validate Host and HTTP/2 authority headers independently of Origin protocol exceptions, including when allowedHosts is "all". Handle malformed open-editor URLs with a controlled response and parse their query without relying on the Host header. (by @​bjohansebas in #​5771)

v6.0.0

Major Changes

• Bump Express to v5. See the Express 5 migration guide for the full list of breaking changes. (by @​bjohansebas in #​5674)

• Bump the webpack peer dependency range from ^5.0.0 to ^5.101.0. (by @​bjohansebas in #​5674)

• Drop support for Node.js < 22.15.0. (by @​bjohansebas in #​5674)

• Convert the source to native ES modules. The package keeps "type": "module" and now exposes both an ESM and a CommonJS build via the exports field: ESM consumers import the native lib/, while CommonJS consumers require() a transpiled dist/ build — so the package works from both ESM and CommonJS, including environments where require(ESM) is not supported. (by @​bjohansebas in #​5674)

• Remove CLI flags. Use the serve command from webpack-cli together with a configuration file or the programmatic API instead. (by @​bjohansebas in #​5674)

• Remove the internalIP and internalIPSync static methods from Server. Resolve the local IP yourself if you need it. (by @​bjohansebas in #​5674)

• Remove the bypass option from proxy configuration. Use the router or context options provided by http-proxy-middleware instead. (by @​bjohansebas in #​5674)

• Remove SockJS support. The webSocketServer option no longer accepts "sockjs"; use the default "ws" transport instead. (by @​bjohansebas in #​5674)

• Remove the spdy dependency. Use the built-in node:http2 module via the server option for HTTP/2 support. (by @​bjohansebas in #​5674)

• Update http-proxy-middleware to v4. See the http-proxy-middleware v3 release notes and v4 release notes for the full list of breaking changes. (by @​bjohansebas in #​5674)

• Update webpack-dev-middleware to v8 and sync originalUrl for middleware compatibility. server.middleware.getFilenameFromUrl() is now asynchronous and resolves to { filename, extra: { stats, outputFileSystem } }. See the webpack-dev-middleware v8 release notes for details. (by @​bjohansebas in #​5674)

Minor Changes

• Add plugin support. webpack-dev-server can now be used as a webpack plugin, integrating with the compiler lifecycle without explicitly passing a compiler, preventing multiple server starts on recompilation, ensuring clean shutdown, and supporting MultiCompiler setups with multiple independent plugin servers. (by @​bjohansebas in #​5674)

• Enable the compression middleware for HTTP/2 connections. (by @​bjohansebas in #​5674)

• Remove the colorette dependency in favor of native ANSI styling. (by @​bjohansebas in #​5674)

• Update chokidar to v5 and extend watchFiles.options.ignored to support glob string patterns via tinyglobby. (by @​bjohansebas in #​5674)

• Use compiler.platform to determine the target environment instead of inspecting the resolved target string. Universal targets ("universal" or ["web", "node"], where compiler.platform.universal is true since webpack 5.108.0) are treated as web targets so the client runtime is injected. (by @​bjohansebas in #​5674)

• Use the WHATWG URL API instead of the deprecated url.parse. (by @​bjohansebas in #​5674)

Patch Changes

• Bump production dependencies, notably open to v11 and p-retry to v8. (by @​bjohansebas in #​5674)

• Reject cross-site requests to the internal open-editor and invalidate endpoints. They performed state-changing actions (opening a file in the editor, forcing a recompilation) on any GET request, so a page the developer visited could trigger them. They now require a same-origin request, validated via Sec-Fetch-Site with an Origin/Host fallback. (by @​bjohansebas in #​5691)

• Treat loopback aliases (127.0.0.1, ::1, localhost) as equivalent in isSameOrigin so the WebSocket client does not reject valid same-origin connections. (by @​bjohansebas in #​5674)

• Migrate the test suite from Jest to node:test and set up the jsdom environment. (by @​bjohansebas in #​5674)

• Update webpack-cli to v7.0.2. (by @​bjohansebas in #​5674)
