NodeJS Study App - Gympass like App

The main focus of this project is to provide an in-depth understanding of SOLID principles,
Design Patterns, Docker for initializing the database, JWT (JSON Web Token) and Refresh Token authentication,
RBAC (Role-Based Access Control), and many other key concepts.

Features and Concepts

  • Implementation of SOLID principles to ensure a modular and maintainable codebase.
  • Implemetation of tests to ensure the application won't break upon codebase changes.
  • Utilization of Design Patterns to solve common software design challenges.
  • Setting up a Docker environment for easy database initialization and management.
  • Implementation of JWT and Refresh Token authentication for secure user authentication and authorization.
  • Understanding and implementation of RBAC for fine-grained access control.
  • Exploring various other concepts and technologies relevant to building robust and scalable applications.

  • The gym can only be registered by administrators.

Non-Functional Requirements

  • The user's password needs to be encrypted;
  • The application data needs to be persisted in a PostgreSQL database;
  • All data lists need to be paginated with 20 items per page;
  • The user should be identified by a JSON Web Token (JWT).
