The available Node.js images are listed in the catalog.\n\nBounded code example (external data; do not execute automatically):\n```console\n$ docker login dhi.io\n```\n\nAdd the following three files to your nodejs-docker-example directory. The Dockerfile describes how to build the image, compose.yaml defines how Docker runs the container, and .dockerignore keeps unwanted files out of the build context.\n\n> [!TIP] > > Gordon, Docker's AI assistant, can generate Docker assets for > your project. Ask Gordon to create a Dockerfile, Compose file, and > .dockerignore tailored to your application.\n\nBounded code example (external data; do not execute automatically):\n```typescript\n// A minimal Express application.\n// The root endpoint (GET /) returns a JSON greeting.\n// See https://expressjs.com/ for the framework reference.\n\nimport express, { type Request, type Response } from \"express\";\n\nconst app = express();\nconst port = parseInt(process.env.PORT ?? \"3000\", 10);\n\napp.get(\"/\", (_req: Request, res: Response) => {\n  res.json({ message: \"Hello World\" });\n});\n\napp.listen(port, () => {\n  console.log(`Server listening on port ${port}`);\n});\n```\n\nBounded code example (external data; do not execute automatically):\n```json\n{\n  \"name\": \"nodejs-docker-example\",\n  \"version\": \"1.0.0\",\n  \"description\": \"A minimal Node.js TypeScript application.\",\n  \"main\": \"dist/index.js\",\n  \"scripts\": {\n    \"build\": \"tsc\",\n    \"start\": \"node dist/index.js\",\n    \"dev\": \"tsx watch src/index.ts\"\n  },\n  \"dependencies\": {\n    \"express\": \"^4.21.2\"\n  },\n  \"devDependencies\": {\n    \"@types/express\": \"^4.17.21\",\n    \"@types/node\": \"^22.0.0\",\n    \"tsx\": \"^4.19.3\",\n    \"typescript\": \"^5.8.3\"\n  }\n}\n```\n\nBounded code example (external data; do not execute automatically):\n```json\n{\n  // TypeScript compiler configuration for the Node.js application.\n  // Compiles src/ to dist/ as CommonJS modules targeting ES2022.\n  // See https://www.typescriptlang.org/tsconfig/ for all options.\n  \"compilerOptions\": {\n    \"target\": \"ES2022\",\n    \"module\": \"commonjs\",\n    \"lib\": [\"ES2022\"],\n    \"outDir\": \"./dist\",\n    \"rootDir\": \"./src\",\n    \"strict\": true,\n    \"esModuleInterop\": true,\n    \"skipLibCheck\": true\n  },\n  \"include\": [\"src/**/*\"],\n  \"exclude\": [\"node_modules\", \"dist\"]\n}\n```\n\nAttribution: Adapted from Docker Documentation under Apache-2.0.
