NextJS example using Keycloak as authentication server.
Keycloak offers a comprehensive solution for managing authentication and authorization in web applications. This system boasts the ability to integrate seamlessly with client applications built on React and Next.js, as well as server applications developed in Node.js. This setup not only facilitates a smooth user experience but also establishes a robust security framework that effectively manages user roles and access rights.
This application exemplifies how to leverage Keycloak to create a secure environment with three distinct levels of authorization: public, user, and admin. It enables users to log in and interact with protected routes based on their designated roles, thereby enhancing the security and usability of both the client and server components.
Role Management: Keycloak allows you to define different user roles, specifically user and admin, ensuring that access is granted based on predetermined permissions.
Multi-Level Authorization: The application incorporates three levels of authorization: public, user, and admin, each with unique actions that can be executed, ensuring tailored access control.
Token Generation: Users are authenticated through the generation of tokens by Keycloak, which securely validates identities and manages session handling.
RESTful API Integration: Provides a robust set of APIs that facilitate user authentication and action execution, all structured around a REST paradigm.
Client-Server Architecture: Easy deployment of the client application alongside the server, allowing for smooth interactions and efficient data flow between components.
User-Friendly Installation: Installation is simplified with Docker, allowing quick deployment of Keycloak and supporting services like MySQL and the web application.
Customizable Configuration: Users can easily clone the repository and adjust configurations, including URL, realm, and clientID, catering to specific project needs.

Next.js is a React-based web framework that enables server-side rendering, static site generation, and other powerful features for building modern web applications.

Tailwind CSS is a utility-first CSS framework that provides pre-defined classes for building responsive and customizable user interfaces.
ESLint is a linter for JavaScript that analyzes code to detect and report on potential problems and errors, as well as enforce consistent code style and best practices, helping developers to write cleaner, more maintainable code.
PostCSS is a popular open-source tool that enables web developers to transform CSS styles with JavaScript plugins. It allows for efficient processing of CSS styles, from applying vendor prefixes to improving browser compatibility, ultimately resulting in cleaner, faster, and more maintainable code.
TypeScript is a superset of JavaScript, providing optional static typing, classes, interfaces, and other features that help developers write more maintainable and scalable code. TypeScript's static typing system can catch errors at compile-time, making it easier to build and maintain large applications.
