Beginner's Guide to Node.js, Express.js, and MongoDB | Complete Tutorial | 7 Hours

📚 This YouTube video is a 7-hour Node.js tutorial consisting of 15 tutorials that build upon each other.

💻 Node.js is a JavaScript runtime that runs on the server, allowing JavaScript to be used on the back end instead of just the front end.

📂 The video covers topics such as working with files and directories, reading and writing files, appending to files, and renaming and deleting files.

📝 Using readable and writable streams in Node.js to efficiently read and write data from files.

🗃️ Creating and manipulating directories in Node.js using the fs module.

📦 Understanding npm and how to install and use packages in Node.js applications.

🧩 Working with events in Node.js and emitting custom events to trigger actions.

📁 Setting up a file system in Node.js to create and manage files

🌐 Creating a web server with Node.js and handling different types of requests

🔀 Implementing redirects and handling 404 errors in the server

📋 The video is about creating a web server using Node.js and Express.js.

⚙️ The video covers topics such as handling data, serving static files, and creating custom routes.

🔧 Built-in middleware like handling form data and JSON, and serving static files are discussed.

🎥 The video is about creating routers in the Express.js framework to handle different routes.

💡 Routers are like mini-apps that handle specific routes and can be created using the 'express.Router()' function.

✅ By creating routers, you can separate and organize your code for different routes, improving scalability and maintainability.

📚 The video is a beginner's tutorial on Node.js that covers various topics, including routing, creating a REST API, and implementing the MVC design pattern.

🧑‍💻 The transcription shows how to use Express.js to create routes and handle HTTP methods like GET, POST, PUT, and DELETE.

🔒 The tutorial also demonstrates how to implement user authorization by simulating a user's database table using a users.json file.

The tutorial covers topics like handling JSON Web Tokens (JWT), implementing authentication and authorization in Node.js using bcrypt, storing and managing JWTs in cookies, and protecting routes with middleware.

The tutorial also includes explanations on using Axios and Fetch API to make HTTP requests, handling CORS errors, and implementing a refresh token mechanism to obtain new access tokens.

💡 Authentication and authorization are different concepts. Authentication refers to verifying someone's identity, while authorization refers to granting access to specific resources.

🔑 JSON Web Tokens (JWT) are used to authenticate users in the Express API and also provide authorization for accessing API endpoints.

🚧 The tutorial demonstrates how to expand the authorization process by adding user roles with specific permissions to the API.

💡 Using Mongoose to connect to MongoDB and create schemas and models for data collections.

📚 Applying the user and employee models to different routes in the API and updating the asynchronous CRUD operations.

✅ Testing the register, auth, refresh token, and logout routes using Thunderclient.

The video is a full course on Node.js for beginners, covering all the essential concepts and functionalities.

The course includes a detailed explanation of CRUD operations (Create, Read, Update, Delete) using MongoDB and Mongoose.

The instructor also demonstrates how to implement user authentication and authorization using JSON Web Tokens (JWT).
