To start our project, the first step is setting up the correct folder structure. Why do you think organizing files is important?
It helps in easily locating files and maintains order?
Exactly! If we keep our files organized, it significantly eases the development process. Our main folder will be called 'task-manager', and inside that we will have a 'public' folder for all front-end files.
What will be in the 'public' folder?
Good question! The 'public' folder will contain our HTML, CSS, and JavaScript files. Essentially, everything needed for the user interface.
And what about 'server.js'?
'server.js' will be the entry point for our back-end application. It will handle all the server-related logic, like listening for requests.
So, each part has a specific role?
Exactly! Each component's role is crucial for keeping the application structured. Let's summarize: we need to create 'public' for front-end files, 'server.js' for back-end logic, and 'package.json' for managing dependencies.
Initializing Node.js Project

After setting up our folder structure, what do we do next?
We initialize the Node.js project?
Correct! We can use the command `npm init -y` to generate a default package.json file. What is the purpose of 'package.json'?
I think it stores details about the project and its dependencies?
Exactly! It includes information about libraries weβre using and scripts for running our application.
Can you show us how to do that?
Absolutely! Just type in the terminal: `npm init -y`. Itβs as simple as that!
What's next after initialization?
Great question! Weβll need to install some dependencies now.
Installing Dependencies

Now that we have our project initialized, which libraries do we need?
We should install Express for handling HTTP requests?
Right! We'll also need the MongoDB driver to communicate with our database, and Nodemon for auto-restarting the server during development.
How do we install them?
You can use the following commands: `npm install express mongodb` and `npm install --save-dev nodemon`. Can anyone tell me why we use --save-dev for Nodemon?
Because it's just for development, not for production?
Exactly! This distinction helps keep our production environment clean. So remember: use `--save-dev` for tools used only during development.

Quick Overview
Standard
In this section, we discuss how to properly organize our project folder, initialize the Node.js project, and install necessary dependencies such as Express and MongoDB driver, which are essential for building and managing our full-stack application effectively.
Detailed
Setting Up the Project
Setting up the project is crucial as it lays the foundation for the development of a full-stack CRUD application. This includes determining the folder structure, initializing the Node.js project, and installing its dependencies.
Folder Structure
The recommended folder structure is as follows:
task-manager/ βββ public/ β βββ index.html β βββ style.css β βββ script.js βββ server.js βββ package.json
- public/ contains the front-end files needed for the user interface.
- server.js acts as the entry point for the back-end.
- package.json manages the projectβs dependencies and scripts.
Initializing Node.js Project
To start a Node.js project:
1. Run npm init -y in your terminal to create a package.json file with default values.
Installing Dependencies
Next, you need to install the necessary libraries to build your application:
- Express for handling HTTP requests.
- MongoDB driver to facilitate database interactions.
- Nodemon for automatically restarting the server during development, enhancing the efficiency of your workflow.
Install them using the following commands:
These steps ensure that your basic project setup is ready, enabling you to focus on developing the applicationβs front-end and back-end functionalities.

task-manager/ βββ public/ β βββ index.html β βββ style.css β βββ script.js βββ server.js βββ package.json
Detailed Explanation
The folder structure defines how the files of our project are organized. In our project, there is a main folder named task-manager. Inside this folder:
- The public directory contains files that the client will interact with, including index.html, which is the main HTML document, style.css for styling, and script.js for the functionality (JavaScript).
- server.js serves as the entry point of our back-end and manages the server-side code.
- package.json is a file that helps us keep track of the dependencies our project needs to run properly. It includes details about the project and libraries we use.
Examples & Analogies
Think of the project structure like a library. The public folder is akin to the reading rooms where visitors access books (HTML, CSS, JS) to read and engage with information. server.js is the librarian (back-end) who manages the requests for books and information. The package.json file serves like a catalog, listing all the books (dependencies) available in the library, helping librarians know what resources are there.

npm init -y This creates package.json.
Detailed Explanation
To start our project, we need to set it up as a Node.js project. Running the command npm init -y initializes a new project and automatically creates a package.json file. This file contains the default settings, including the name, version, and description of our project, which we can later modify as needed.
Examples & Analogies
Imagine starting a new business. Just as you would need to register your business and get the necessary documentation (like a business license), initializing a Node.js project is similar. The package.json file is like that registration document providing essential information about your businessβthe projectβso that others understand what it is about.

npm install express mongodb
npm install --save-dev nodemon
- Express: Framework for handling HTTP requests.
- MongoDB driver: Connects Node.js to MongoDB.
- Nodemon: Automatically restarts the server during development.
Detailed Explanation
Next, we install the necessary dependencies for our project to work. The command npm install express mongodb adds Express, a framework that makes it easy to handle HTTP requests, and the MongoDB driver that allows our application to connect and interact with a MongoDB database. By using npm install --save-dev nodemon, we also install Nodemon, a tool that automatically restarts our server when we make changes to the code, streamlining the development process.
Examples & Analogies
Think of these dependencies like the tools and ingredients needed to run a restaurant. Just as a chef needs specific tools (knives, pots) and ingredients (vegetables, spices) to create dishes, our project needs Express and MongoDB to function effectively. Nodemon is like an assistant who immediately informs the chef when a dish is updated, ensuring that the kitchen is always running smoothly without delays.
