Activity Tracker App
Prompt
Build a full-stack activity tracking application using React.js and Node.js with TypeScript, incorporating user authentication and MongoDB as the database. Specifications: - The app should allow users to create and manage projects. - Each project can have multiple tasks associated with it. - Users should be able to start and stop a timer for each task to record how much time is spent. - Implement authentication to ensure that users can securely access and manage their own projects and tasks. - Use TypeScript for both frontend and backend code. - The backend should be built with Node.js, using Express.js or similar framework. - Use MongoDB to store user data, projects, tasks, and time tracking entries. Step-by-step guidance: 1. Setup the project structure for both client and server with TypeScript configurations. 2. Design and implement MongoDB schemas/models for users, projects, tasks, and timer entries. 3. Build API endpoints for authentication (register, login, logout) and CRUD operations for projects and tasks. 4. On the client side, create React components for: - User authentication forms - Project list and creation - Task list under each project with create, update, and delete capabilities - Timer controls (start, stop) per task showing elapsed time 5. Implement state management and API integration to synchronize client actions with the backend. 6. Ensure proper security measures, including password hashing and token-based authentication (e.g., JWT). 7. Provide error handling and feedback for user interactions. Output Format: Provide the full file structure and code files necessary for the application, organized into backend and frontend directories, each including configuration files, source code files written in TypeScript, and README files with setup instructions. Include sample code snippets demonstrating how projects and tasks are created, how timers start and stop, and how authentication is handled. Notes: - Focus on the core functionality first (projects, tasks, timers, authentication), then optionally add advanced reporting features. - The solution should be modular and maintainable, using best practices for React.js, Node.js, and MongoDB. - Assume the user has basic environment setup (Node.js, npm, MongoDB) but include necessary commands to run the project.
