Today, we will look at how to create a web application that allows students to submit feedback. What technologies do you think we might use for such a project?
Maybe HTML for the structure?
Exactly! We'll use HTML for the layout. We'll also use CSS for styling and making it visually appealing.
And JavaScript for making it interactive?
Correct! JavaScript will help us with form submissions and dynamically updating the displayed feedback. Remember the acronym HCC? It stands for HTML, CSS, and JavaScript.
Backend Implementation

Let's delve into the backend now. Who can tell me why we might use Node.js for this project?
I think it’s good for handling server requests efficiently!
Exactly! Node.js provides an excellent way to write JavaScript on the server side. We will use Express.js to handle our routes for fetching and submitting feedback. Can anyone recall what JSON is?
It's a format for storing and exchanging data, right?
Spot on! We will use JSON to store the feedback data in a file, acting like a simple database.
How do we actually save the feedback?
We’ll use the POST method to save feedback data to our JSON file. Remember, HTTP methods allow us to interact with our server in different ways.
Frontend Interaction

Now, let's discuss how the frontend interacts with our backend. Can anyone summarize how we send feedback from the form to the server?
We use the Fetch API to send a POST request with the form data?
Exactly! The Fetch API allows us to make requests easily. When we submit the form, we gather the input data and send it to the server.
What happens to the data once it’s sent?
Great question! The server receives the data, saves it in our JSON file, and we can show it back on the webpage using DOM manipulation.
Final Review and Deployment

Before we finish, let’s summarize how you can run this application. What command do we use?
We run ‘node server.js’ in the terminal!
Correct! This starts our server. Then we can open our web browser and go to 'http://localhost:3000' to see our app. Can anyone think of potential improvements for this project?
We could add validation for the feedback form!
Definitely! Improving user experience through form validation is a great step. Always think about how to enhance your applications.
Introduction & Overview
Read a summary of the section's main ideas. Choose from Basic, Medium, or Detailed.
Quick Overview
Standard
The summary outlines the development of a web application that allows students to submit feedback through a form, with the backend managing storage and retrieval of feedback. It highlights the combination of HTML, CSS, JavaScript, Node.js, and Express.js to create a functional project.
Detailed
Detailed Summary
In this section, you learned about building a full-stack web application designed for collecting student feedback. The project involves using:
- HTML & CSS: These technologies form the frontend interface where students can input their feedback.
- JavaScript: This is utilized for dynamic behavior in the application, particularly in manipulating the DOM and making API calls.
- Node.js and Express.js: These technologies power the backend, allowing it to handle requests and manage data.
- JSON file storage which emulates a mini database, storing all feedback submitted by users.
The project's goal is to create an easy-to-use feedback form, submit user inputs via JavaScript's Fetch API, and display previously submitted feedback through a structured system. You also explored how to set up the project folder structure, install necessary packages, and write server and client-side code effectively. This concise combination of tools serves to demonstrate the broad capabilities of web development while providing a practical application for students to express their thoughts.

You just built your first Full Stack project using:
Detailed Explanation
This summary highlights the key components of the project you just completed. A Full Stack project involves both frontend and backend development. In this case, the frontend is created using HTML, CSS, and JavaScript, while the backend consists of a Node.js server that uses Express.js. You also learned how to store data in a JSON file, acting as a mini database.
Examples & Analogies
Think of a Full Stack project like building a restaurant. The frontend is like the dining area where patrons enjoy their meals (the part clients see and interact with). The backend is like the kitchen where chefs prepare food (the server handling requests). Lastly, the storage (JSON file) is like the pantry, keeping all the ingredients until they are needed.

● HTML + CSS for frontend layout
Detailed Explanation
HTML (HyperText Markup Language) and CSS (Cascading Style Sheets) are essential for creating the structure and style of a webpage. HTML provides the basic structure (like headers, forms, and content), while CSS is used to style that structure (like colors, fonts, and layouts). In your project, you used these technologies to create a user-friendly feedback form.
Examples & Analogies
Imagine building a house. HTML is like the framework of the house – it gives it shape and structure. CSS is like the interior design and paint – it makes the house visually appealing and pleasant to live in.
Dynamic Behavior with JavaScript

● JavaScript for dynamic behavior
Detailed Explanation
JavaScript is a programming language that allows you to create dynamic content on your webpages. This means that users can interact with the site, and the site can respond in real time. In your project, JavaScript was used to handle form submissions and dynamically update the displayed feedback without refreshing the page.
Examples & Analogies
Think of JavaScript as a waiter in a restaurant. The waiter takes orders from customers (the user interaction) and informs the kitchen (the server) of what to prepare. The waiter also brings back food and updates customers on their orders, making the dining experience smooth and efficient.

● Node.js + Express.js for server
Detailed Explanation
Node.js is a runtime environment allowing you to run JavaScript on the server side, while Express.js is a framework that simplifies the process of building web servers. In your project, these technologies were used to create a server that listens for requests from the frontend, retrieves existing feedback, and accepts new submissions.
Examples & Analogies
Consider Node.js as the restaurant's kitchen where all orders are prepared. Express.js acts like the head chef, managing the kitchen efficiently by directing staff on how to prepare each dish (handling requests and responses).
Data Storage

● JSON file for backend storage (like a mini database)
Detailed Explanation
JSON (JavaScript Object Notation) is a lightweight data format that is easy for humans to read and write and easy for machines to parse and generate. In this project, feedback was stored in a JSON file which acts like a database, holding records of user feedback submitted through the form.
Examples & Analogies
Imagine a library where all books are categorized and stored. The JSON file works like the library's catalog system – it keeps track of all the feedback (books) submitted by users (readers), making it easy to access and retrieve when needed.
