Node Js Roadmap

Before starting the Node.js, it’s essential to ensure that several prerequisites are in place:

  1. Understand JavaScript Fundamentals:
    • Learn the basics of JavaScript, including variables, data types, functions, loops, and objects.
    • Familiarize yourself with ES6 (ECMAScript 2015) features such as arrow functions, template literals, destructuring, and classes.
  2. Learn Asynchronous JavaScript:
    • Understand asynchronous programming concepts like callbacks, promises, and async/await.
    • Explore how asynchronous operations work in JavaScript, such as setTimeout, setInterval, and handling asynchronous events.
  3. Install Node.js:
    • Download and install Node.js from the official website.
    • Verify the installation by running node -v in your terminal or command prompt.
  4. Basic Node.js Concepts:
    • Get familiar with core Node.js concepts like modules, the event loop, and the global object.
    • Learn how to use built-in modules like fs (file system) and http to perform basic I/O operations and create web servers.
  5. Explore NPM (Node Package Manager):
    • Understand the role of npm in managing Node.js packages and dependencies.
    • Learn how to initialize a new Node.js project using npm init and how to install packages using npm install.
  6. Build a Simple Application:
    • Start with a simple project to apply your knowledge of Node.js.
    • Create a basic web server using the built-in http module or popular frameworks like Express.js.
  7. Setup Express.js:
    • Dive deeper into Express.js, a minimalist web framework for Node.js.
    • Learn how to handle routes, middleware, request/response objects, and templating engines.
  8. Database Integration:
    • Explore integrating Node.js with databases like MongoDB, MySQL, or PostgreSQL.
    • Learn about database drivers and ORM (Object-Relational Mapping) libraries available for Node.js.
  9. Authentication and Authorization:
    • Understand how to implement user authentication and authorization in Node.js applications.
    • Explore authentication strategies like JWT (JSON Web Tokens) and OAuth.
  10. Error Handling and Debugging:
    • Learn best practices for error handling and debugging Node.js applications.
    • Familiarize yourself with tools like Node.js debugger, console.log, and error middleware.
  11. Building APIs::
    • CURD APIs.
    • Files uploads and retrieve .
  12. Deployment:
    • Understand the process of deploying Node.js applications to production environments.
    • Explore platforms like Heroku, AWS, or DigitalOcean for hosting your Node.js applications.
