`

🚀 Usage

`bash
import express from "express";
import { asyncHandler, jsonHandler, wrapRouter } from "express-async-handler-plus";

const app = express();

// ✅ Example route with asyncHandler
app.get(
"/hello",
asyncHandler(async (req, res) => {
// Simulate async work
const user = await Promise.resolve({ id: 1, name: "Manu" });
res.json({ success: true, user });
})
);

// ✅ Example route with jsonHandler (auto JSON response)
app.get(
"/auto",
jsonHandler(async () => {
return { msg: "Auto JSON handled!" };
})
);

// ✅ Example wrapped router
const router = express.Router();
router.get(
"/data",
async (req, res) => {
// No need to wrap manually
return { items: [1, 2, 3] };
}
);

app.use("/api", wrapRouter(router));

app.listen(3000, () => console.log("🚀 Server running on http://localhost:3000"));
`
