The same endpoint in Express

The ergonomic jump

Now the same GET /walkers, in Express — the minimal, unopinionated web framework that most Node backends start from. Watch how much of the raw boilerplate disappears:

• No manual req.method === "GET" / req.url === "/walkers" matching — you register app.get("/walkers", …) and Express routes it.
• No setHeader + JSON.stringify + res.end — res.json(walkers) sets Content-Type: application/json, serializes, and sends in one call.
• Path parameters like /walkers/:id are parsed for you into req.params.id.
