Feedback form using PugJs, NodeJS, MongoDB, Express
  • Difficulty Level : Medium
  • Last Updated : 20 Dec, 2020

We can create a feedback form using PugJs, NodeJS, MongoDB, Express with the following steps. A feedback form takes the input from the user and sends the data to the server to process it and store it accordingly into the database.

Step 1: Create a feedback_form named folder in any directory. You can take any name.

Step 2: Initialize the NodeJS project using the following command.

npm init  –y

Step 3: Install the required modules using the following command from your terminal/cmd.



// Express middleware
npm install express  --save 

// Database setup
npm install mongoose  --save 

// pugjs for client site rendering
npm install pug  --save 

// OR you can install all command
// using single command
npm install express pug mongoose

Step 4: Directory structure will look like the following.

Directory structure

  • node_modules: It contains all our installed node modules.
  • static: It contains the static files for your server.
  • views: It contains PugJS files to render to the client site.
  • app.js: It contains the server code to run this application.

Step 5: After installing modules, write down the following codes in order to create a feedback form.

// Require express to make easy
// routing on server side.
const express = require("express");
  
// Creating express object
const app = express();
  
// Require path module
const path = require('path');
  
// Require pug template engine
const pug = require("pug");
  
// Require mongoose to use mongoDb
// in a easier way
const mongoose = require("mongoose");
  
// Define a port number
const port = 3000;
  
// Make a static route to use your
// static files in client side
app.use('/static', express.static('static'));
  
// Middleware for parsing
app.use(express.urlencoded());
  
// Define and use pug engine so also
// declare path on rendering
app.set('view engine', 'pug');
app.set('views', path.join(__dirname, 'views'));
  
// Database Connection 
mongoose.connect(
    { useUnifiedTopology: true }
);
  
// Create schema
const feedSchecma = mongoose.Schema({
    name: String,
    email: String,
    feed: String
});
  
// Making a modal on our already
// defined schema
const feedModal = mongoose
    .model('feeds', feedSchecma);
  
// Handling get request
app.get('/', function (req, res) {
    // Rendering your form
    res.render('feedback_form');
});
  
// Handling data after submission of form
app.post("/feedback_form", function (req, res) {
    const feedData = new feedModal({
        name: req.body.name,
        email: req.body.email,
        feed: req.body.feedback
    });
    feedData.save()
        .then(data => {
            res.render('feedback_form',
{ msg: "Your feedback successfully saved." });
        })
        .catch(err => {
            res.render('feedback_form'
                { msg: "Check Details." });
        });
})
  
// Server setup
app.listen(port, () => {
    console.log("server is runing");
});
