Introduction:

In today’s digital world, user authentication is a crucial aspect of web development. Whether you’re building a simple blog or a complex web application, implementing a secure login system is essential to protect user data and ensure a seamless user experience. In this tutorial, we’ll walk through the process of building a login application using three powerful technologies: React for the frontend, Node.js for the backend, Typescript for JavaScript with static typing, improving code safety and maintainability, and PostgreSQL for the database from beginner to advanced level.

Overview of Technologies:

Before we dive into the implementation, it is always important to understand the underlined concepts before a deeper dive. Let’s briefly discuss each technology’s role in our application:

  • React: React offers a robust framework for dynamic web UIs. Its component-based design and virtual DOM streamline complex UI creation, enhancing code quality, scalability, and performance.
  • Node.js: enables efficient server-side JavaScript development, leveraging its non-blocking I/O model and vast ecosystem for scalable, real-time applications, streamlining…
