Designing the system architecture for a MERN (MongoDB, Express.js, React.js, Node.js) stack-based fitness application involves breaking down the application into various components and deciding how they interact with each other. Here's a high-level overview of the architecture:

1. Frontend (React.js)

• The frontend will be built using React.js, which will handle the user interface and user interactions.
• Components such as user authentication, workout tracking, exercise videos, progress charts, etc., will be developed using React components.
• Redux or Context API can be used for state management to handle application-wide state.

2. Backend (Node.js with Express.js):

• Express.js will serve as the backend framework for handling HTTP requests and responses.
• APIs will be created for functionalities like user authentication, CRUD operations for workouts, exercises, user profiles, etc.
• Express middleware can be used for tasks like request validation, authentication, logging, etc.
• MongoDB will be used as the database to store application data. Mongoose ODM (Object Data Modeling) can be used to interact with MongoDB from Node.js.

3. Database (MongoDB)

• MongoDB will be used as the NoSQL database to store user data, workout plans, exercises, progress logs, etc.
• Data will be organized into collections such as users, workouts, exercises, progress, etc.
• Indexing and schema design should be optimized for efficient querying and scalability.

4. Authentication

• JSON Web Tokens (JWT) can be used for user authentication and authorization. When a user logs in, they receive a JWT which they include in subsequent requests to authenticate themselves.
• bcrypt or similar libraries can be used for password hashing to securely store user passwords.

5. File Storage

• For storing exercise images or videos, a cloud storage service like Amazon S3 or Google Cloud Storage can be utilized. The backend can then store the URLs of these files in the database.

6. Deployment

• The frontend can be deployed to a static hosting service like Netlify or Vercel.
