"teaser_article_markdown": "# Build a Secure HTTP/2 API Gateway with HTTP2Shell (≈600 words)\n\n*Prerequisites\n- Node.js ≥ 18 (for native HTTP/2 support)\n- Basic knowledge of TLS certificates\n- Docker (optional, for containerized deployment)\n\n## 1. Why HTTP2Shell?\nHTTP2Shell is the evolution of the popular Node2Shell library, providing a thin wrapper around Node’s native HTTP/2 API while exposing a shell‑like routing DSL. It lets you write concise request handlers, stream large payloads efficiently, and leverage HTTP/2 multiplexing without the boilerplate of raw http2 streams.\n\n## 2. Install & Quick Start\n
bash\nnpm install http2shell\n
\nCreate a file **gateway.js*:\n
js\nimport { createServer } from \"http2shell\";\nimport fs from \"fs\";\n\n// Load TLS certs – HTTP/2 requires HTTPS\nconst server = createServer({\n key: fs.readFileSync(\"./certs/server.key\"),\n cert: fs.readFileSync(\"./certs/server.crt\")\n});\n\n// Simple health‑check endpoint\nserver.get(\"/health\", (req, res) => {\n res.json({ status: \"ok\", ts: Date.now() });\n});\n\n// Echo endpoint that streams request body back to the client\nserver.post(\"/echo\", async (req, res) => {\n // `req.stream` is a Node.js readable stream\n res.stream(req.stream);\n});\n\n// Start listening on 8443\nserver.listen(8443, () => console.log(\"HTTP/2 gateway listening on :8443\"));\n
\nRun it with node gateway.js. Your API
