Go and Vanilla JS: Building Authentication APIs

Securing user access is fundamental for almost any web application. Without a solid understanding of authentication, your applications are vulnerable. This course guides you through the essential principles and practical steps to build secure authentication APIs from the ground up. By the end of this course, you will be able to design, implement, and integrate a complete user authentication system using Go for the backend and Vanilla JavaScript for the frontend, without relying on complex frameworks. What you'll learn: * Understand core authentication concepts, including session management and token-based systems. * Design and implement robust API endpoints in Go for user registration and login. * Apply secure password hashing techniques and best practices for storing user credentials. * Integrate and consume authentication APIs from the frontend using modern Vanilla JS Fetch API. * Implement secure client-side storage and handling of authentication tokens and HttpOnly cookies. * Configure and manage JSON Web Tokens (JWTs) for stateless authentication and authorization. This course begins with foundational authentication concepts, progresses to backend API development in Go, and concludes with frontend integration using Vanilla JavaScript. You will learn to establish secure communication between client and server. This course is designed for beginners with basic programming knowledge who want to build secure fullstack web applications without relying on extensive frameworks. No prior experience with Go or authentication systems is required. Start building secure and functional user authentication into your applications today.
