1: We need to create a Contact Schema and Model

const { Schema, model } = require("mongoose");  
const contactSchema = new Schema({ username: { type: String, required: true }, email: { type: String, required: true },  
 message: { type: String, required: true }, }); 
 // create a new collections(Model) 
const Contact = new model("Contact", contactSchema); module.exports = Contact;  

2: We need to create the contact route.

const express = require("express");
const router = express.Router();

const contactForm = require("../controllers/contact-controller");

router.route("/contact").post(contactForm);

module.exports = router;

3: We need to define the logics of contact in our Contact-controller.js file

const Contact = require("../models/contact-model");

const contactForm = async (req, res) => {
  try {
    const response = req.body;
    await Contact.create(response);
    return res.status(200).json({ message: "message send successfully" });
  } catch (error) {
    console.error(error);
    return res.status(500).json({ message: "message not delivered" });
  }
};

module.exports = contactForm;

4: Add the contact route in our server.js file

require("dotenv").config();
const express = require("express");
const app = express();
const router = require("./routes/auth-route");
const connectDb = require("./utils/db");
const errorMiddleware = require("./middlewares/error-middleware");
const contactRoute = require("./routes/contact-route");

// to get the json data in express app.
app.use(express.json());

// Mount the Router: To use the router in your main Express app, you can "mount" it at a specific URL prefix
app.use("/api/auth", router);
app.use("/api/form", contactRoute);

app.use(errorMiddleware);

const PORT = 5000;
connectDb().then(() => {
  app.listen(PORT, () => {
    console.log(`server is running at port: ${PORT}`);
  });
});

This is how it will looks like in our postman app.
