Our `@nx/next:server` executor is integrated to use Next.js' CLI. You can read more about the serve options at [Next.js CLI Options](https://nextjs.org/docs/app/api-reference/next-cli)\n\n```json\n \"serve\": {\n \"executor\": \"@nx/next:server\",\n \"defaultConfiguration\": \"development\",\n \"options\": {\n \"buildTarget\": \"acme:build\",\n \"dev\": true\n },\n \"configurations\": {\n \"development\": {\n \"buildTarget\": \"acme:build:development\",\n \"dev\": true\n },\n \"production\": {\n \"buildTarget\": \"acme:build:production\",\n \"dev\": false\n }\n }\n },\n```\n\n{% /tab %}\n{% tab label=\"Enable turbo\" %}\n\nTurbopack (beta) is a cutting-edge bundler designed for JavaScript and TypeScript. To read more about support features see [Next.js Turbopack Doucmentation](https://turbo.build/pack/docs/features)\n\nIn the context of Nx, you can utilize Turbopack within both the `pages` and `app` directories of Next.js to enhance local development speed. To activate Turbopack, simply:\n\nAppend the `--turbo` flag while executing the Nx development server.\n\n```shell\nnx run acme:serve --turbo\n```\n\nUpdating the build options to include `turbo`.\n\n```json\n \"serve\": {\n \"executor\": \"@nx/next:server\",\n \"defaultConfiguration\": \"development\",\n \"options\": {\n \"buildTarget\": \"acme:build\",\n \"dev\": true\n },\n \"configurations\": {\n \"development\": {\n \"buildTarget\": \"acme:build:development\",\n \"dev\": true,\n \"turbo\": true\n },\n //\n }\n }\n```\n\n```bash\nnx run acme:serve\n```\n\n{% /tab %}\n\n{% tab label=\"Adding keep alive timeout\" %}\n\nWhen using Nx with Next.js behind a downstream proxy, it's important to make sure that the `keep-alive timeouts` of Next.js' HTTP server are set to longer durations than the timeouts of the proxy. If you don't do this, Node.js will unexpectedly end TCP connections without notifying the proxy when the `keep-alive timeout` is reached. This can lead to a proxy error when the proxy tries to reuse a connection that Node.js has already terminated.\n\nTo configure timeout values (in milliseconds) you can:\n\nPass `--keepAliveTimeout`\n\n```shell\nnx run acme:serve --keepAliveTimeout 60000\n```\n\nUpdating the serve options to include `keepAliveTimeout`.\n\n```json\n \"serve\": {\n \"executor\": \"@nx/next:server\",\n \"defaultConfiguration\": \"development\",\n \"options\": {\n \"buildTarget\": \"acme:build\",\n \"dev\": true\n },\n \"configurations\": {\n \"development\": {\n \"buildTarget\": \"acme:build:development\",\n \"dev\": true,\n \"keepAliveTimeout\": 60000\n },\n //\n }\n }\n```\n\n```shell\nnx run acme:serve\n```\n\n{% /tab %}\n\n{% /tabs %}\n",
