# Directory Structure for Notes App Project
This document outlines the expected and standardized directory structure for the "Notes App" project. This structure is designed to ensure consistency, separation of concerns, and efficient development, deployment, and maintenance.
**Note:** This is a documentation of the intended structure. For base projects, this agent *only documents* the existing or desired structure and *does not create* any files or directories itself. Subsequent agents (like the Developer or DevOps agents) will populate these directories and create necessary configuration files.

**Customizations for Notes App Project:**
* **`backend/`**: This directory is designated for the server-side application logic of the Notes App. It will contain the API endpoints necessary for managing notes (creating, retrieving, updating, deleting), handling user authentication, and interacting with the database where notes are stored. Typical contents might include application code, database models, business logic services, and API controllers.
* **`frontend/`**: This directory will host all client-side code responsible for the user interface of the Notes App. This includes UI components (e.g., a note list, note editor), styling, and client-side logic to communicate with the `backend/` API to display, edit, and save notes. This could be a Single Page Application (SPA) built with frameworks like React, Vue, or Angular.
* **Configuration Files**: The root-level configuration files (`Dockerfile.backend`, `Dockerfile.frontend`, `docker-compose.yml`, `deployment_config.yml`) will be tailored specifically to define, build, run, and deploy the Notes App services. `docker-compose.yml` will likely include services for the backend, frontend, and a database (e.g., PostgreSQL, MongoDB) required by the Notes App.

# io8 System Architect Agent - Customized for This Project
## Project-Specific Instructions
# Architecture Document
Generated: 2025-10-02T[CURRENT_TIMESTAMP]
## System Overview
The "Notes App" is a full-stack web application designed for personal note management. It enables users to securely register, log in, and perform CRUD (Create, Read, Update, Delete) operations on their notes. Phase 2 enhancements include advanced features such as search, filtering, rich text editing, and tagging for improved organization. The frontend is built with Angular, leveraging the Clarity Design System from the base project for a consistent and intuitive user interface. The backend will expose a RESTful API to manage user authentication, notes, and associated metadata, ensuring data persistence and security.
## Architecture Pattern
### Client-Server Architecture
The application will follow a classic client-server architecture, where the Angular frontend acts as the client consuming services provided by a dedicated backend API.
### Layered Backend Architecture
The backend will implement a layered architecture to ensure separation of concerns, maintainability, and scalability:
1. **Presentation Layer (API/Controllers):** Handles HTTP requests, authentication, request parsing, and response formatting. Exposes RESTful endpoints.
2. **Service/Business Logic Layer:** Contains the core business logic, orchestrates operations, and applies business rules (e.g., password policies, note ownership validation).
3. **Data Access Layer (Repository/ORM):** Abstracts database interactions, performing CRUD operations, handling data mapping, and managing transactions.
## Component Design
### Frontend (Angular - Leveraging Clarity Boilerplate)
* **Auth Module:** Encapsulates components for user registration, login, and potentially password reset/change. Includes `AuthService` for API interaction and `AuthGuard` for route protection.
* **Notes Module:** Manages all note-related functionalities. Contains components for:
* `NotesListComponent`: Displays a paginated/filtered list of notes. Incorporates search and filter UI.
* `NoteDetailComponent`: Displays a single note's content.
* `NoteEditorComponent`: Used for creating and editing notes. Integrates a rich text editor and tag input.
* **Core Module:** (From boilerplate) Provides singleton services like `AuthenticationService` (managing JWT tokens, user state), `ErrorInterceptor` (for global API error handling), and `LoggerService`.
* **Shared Module:** (From boilerplate) Contains reusable UI components (e.g., custom card, loader, pagination controls), directives, and pipes that are used across multiple feature modules. Will include components related to tag display (e.g., Clarity labels).
* **Layout Components:** (From boilerplate) `HeaderComponent` (with user profile/logout), `SidebarComponent` (for navigation to notes list, future dashboards).
### Backend (RESTful API)
* **Authentication Service/Controller:** Endpoints for `/api/auth/register`, `/api/auth/login`, `/api/auth/logout`. Handles user creation, password hashing, JWT generation, and token validation.
* **User Service/Controller:** Manages user-specific data (e.g., `/api/users/{id}`). Primarily for internal use or administrative purposes, potentially for user profile updates.
* **Notes Service/Controller:** Provides CRUD operations for notes. Endpoints like `/api/notes`, `/api/notes/{id}`. Includes logic for search, filter, and tagging notes based on user ownership.
* **Tag Service/Controller:** (If implemented as a separate entity) Manages user-defined tags. Endpoints like `/api/tags`.
* **Data Access Layer:** Interfaces with the chosen database via an ORM (Object-Relational Mapper). Maps database entities to application objects (e.g., `User` entity, `Note` entity, `Tag` entity).
## Data Architecture
**Database Type:** Relational Database (e.g., PostgreSQL).
### Entities and Relationships:
1. **User:**
* `id` (Primary Key, UUID)
* `username` (Unique, String)
* `password_hash` (String, for securely stored password)
* `email` (Unique, String, Optional if username is primary identifier for login)
* `created_at` (Timestamp)
* `updated_at` (Timestamp)
* *Relationship:* One User has many Notes.
2. **Note:**
* `id` (Primary Key, UUID)
* `user_id` (Foreign Key to User.id, Required)
* `title` (String)
* `content` (Text type, to accommodate rich text/Markdown)
* `created_at` (Timestamp)
* `updated_at` (Timestamp)
* *Relationship:* One Note belongs to one User. Many-to-many with Tags (via `Note_Tag` join table).
3. **Tag:** (For Phase 2 advanced tagging)
* `id` (Primary Key, UUID)
* `user_id` (Foreign Key to User.id, Required - Tags are user-specific)
* `name` (String, Unique per user)
* *Relationship:* Many-to-many with Notes (via `Note_Tag` join table).
4. **Note_Tag (Join Table):**
* `note_id` (Foreign Key to Note.id)
* `tag_id` (Foreign Key to Tag.id)
* *Composite Primary Key:* (`note_id`, `tag_id`)
### Data Flow:
* Frontend sends HTTP requests (JSON payload) to backend API.
* Backend API processes requests, interacts with the database via DAL/ORM.
* Database stores and retrieves data.
* Backend sends HTTP responses (JSON payload) back to the frontend.
* Frontend processes responses, updates UI, and displays data.
## API Design
RESTful API adhering to standard HTTP methods and resource-based URLs. JSON will be the primary data exchange format. All user-specific endpoints will require authentication.
### Authentication Endpoints (`/api/auth`)
* `POST /api/auth/register`: Create a new user account.
* Request: `{ username, email, password }`
* Response: `{ userId, username }` (or JWT token directly)
* `POST /api/auth/login`: Authenticate user and issue JWT.

* Response: `[{id, name}]`
* `POST /api/tags`: Create a new tag for the authenticated user.
* Request: `{ name }`

* `DELETE /api/tags/{id}`: Delete a specific tag by ID for the authenticated user.
* Response: `{ message: "Tag deleted successfully" }`
## Security Architecture
* **User Authentication:** JWT (JSON Web Tokens) will be used for stateless authentication. Access tokens will be short-lived, and optionally refresh tokens can be used for seamless re-authentication.
* **Password Hashing:** User passwords will be hashed using a strong, adaptive hashing algorithm (e.g., bcrypt) with a sufficient salt value before storage in the database.
* **Data in Transit:** All communication between the frontend and backend will be secured using HTTPS (TLS/SSL encryption).
* **Authorization:** Backend API endpoints will implement authorization checks to ensure that a user can only access, modify, or delete their own notes and tags. This will be enforced by validating the JWT and verifying the `userId` associated with the request against the `userId` linked to the resource.
* **Input Validation & Sanitization:** Both frontend and backend will perform rigorous input validation. Frontend validation provides immediate feedback, while backend validation is critical for security to prevent common vulnerabilities like SQL Injection, XSS (Cross-Site Scripting), and other data integrity issues. Rich text content will require careful sanitization to prevent XSS.
* **Rate Limiting:** Authentication endpoints (`/api/auth/login`, `/api/auth/register`) will implement rate limiting to mitigate brute-force and denial-of-service attacks.
* **CORS (Cross-Origin Resource Sharing):** The backend API will be configured to correctly handle CORS policies, allowing requests only from the trusted frontend application origin.
## Scalability Considerations
* **Stateless Backend:** The use of JWT for authentication will keep the backend stateless, allowing for easy horizontal scaling of API instances.
* **Database Optimization:** Use of a robust relational database (PostgreSQL) with proper indexing on `userId`, `createdAt`, `updatedAt`, `title`, and `content` (for search) will ensure efficient query performance even with large datasets.
* **Caching:** For future scalability, a caching layer (e.g., Redis) could be introduced to cache frequently accessed notes or search results, reducing database load.
* **Containerization:** The application components (frontend, backend, database) will be containerized using Docker, facilitating consistent deployment and scaling in environments like Kubernetes or Docker Swarm.
* **Modular Frontend:** Angular's modular structure and lazy-loading for feature modules contribute to a scalable and performant frontend by reducing initial bundle size.

# io8 Project Builder Plan: notes_app_20251002_055810
This document outlines the project builder plan for the `notes_app_20251002_055810` project, orchestrated using io8 MCP.
## 1. High-Level Scaffolding Plan
### Backend (Spring Boot)
- **Core Application Structure**: Standard Spring Boot application with `src/main/java` for source code, `src/main/resources` for configurations, and `src/test/java` for tests.
- **API Endpoints**: RESTful API endpoints for managing notes (create, read, update, delete).
- **Database Integration**: MySQL database integration using Spring Data JPA for persistence.
- **Business Logic**: Service layer to encapsulate business rules for note management.
- **Security**: Basic security setup (if required by architecture document, otherwise default Spring Security).
### Frontend (Angular Clarity)
- **Application Structure**: Standard Angular project structure with modules, components, services, and routing.
- **UI Components**: Clarity Design System components for a consistent and accessible user interface.
- **Note Management Views**:
- List view to display all notes.
- Detail view for individual note creation/editing.
- **API Integration**: Services to interact with the backend API for note data.
- **Routing**: Angular Router for navigation between different views.
## 2. Directory and File Scaffolding Strategy
The project will follow a standard directory structure for Spring Boot and Angular applications, as generated by io8 MCP and further refined by `git pull`.
### Backend (notes_app_20251002_055810-b)
- `src/main/java/com/example/notesapp/`: Main application code.
- `controller/`: REST controllers (e.g., `NotesController.java`).
- `service/`: Business logic (e.g., `NotesService.java`, `NotesServiceImpl.java`).
- `repository/`: Data access layer (e.g., `NotesRepository.java`).
- `model/`: JPA entities (e.g., `Note.java`).
- `NotesappApplication.java`: Main Spring Boot application class.
- `src/main/resources/`: Configuration files.
- `application.properties` or `application.yml`: Spring Boot configuration.
- `schema.sql`, `data.sql`: Database schema and initial data (if needed).
- `src/test/java/`: Unit and integration tests.
### Frontend (notes_app_20251002_055810-f)
- `src/app/`: Main application module.
- `components/`: Reusable UI components (e.g., `note-list/`, `note-detail/`).
- `services/`: Services for API interaction and data management (e.g., `notes.service.ts`).
- `models/`: TypeScript interfaces for data structures (e.g., `note.ts`).
- `app-routing.module.ts`: Application routing.
- `app.component.ts`, `app.component.html`, `app.component.css`: Root component.
- `src/environments/`: Environment-specific configurations.
- `src/assets/`: Static assets.
## 3. Build Tools and Scripts
- **Backend**:
- **Maven/Gradle**: For dependency management, compilation, testing, and packaging.
- **io8 MCP Build App**: The `build_app` command (already executed) triggers the initial code generation and build process on the io8 platform.
- **Frontend**:
- **Angular CLI**: For generating components, services, modules, and building the application.
- **npm/yarn**: For package management.
- **Git**: For version control and pulling generated code from the Gitea repository.
## 4. Pre-Developer Checks
Before developers begin working on the project, the following checks should be performed:
- **`create_project.out`**: Verify that the `create_project.out` file exists in `.sureai/io8_mcp/responses/` and contains valid project, backend, and module IDs, along with the Gitea URL.
- **`build_app.out`**: Confirm that `build_app.out` exists and indicates a successful build.
- **Git Repository Clone**: Ensure the project repository has been successfully cloned from the `gitea_url` into the local working directory. Check for the presence of backend and frontend project files.
- **`architecture_document.md`**: If present, ensure developers are familiar with the architectural decisions and technology choices outlined in `.sureai/architecture_document.md`.
- **Initial Build Verification**: Developers should perform an initial local build of both the backend and frontend applications to ensure all dependencies are resolved and the generated code compiles without errors.
- **Wireframe Verification**: Confirm that the `create_wireframe.out` file exists and the wireframe fields align with the initial requirements for the "notes app".

## DIRECTORY STRUCTURE UPDATE - 2025-10-02 06:07:31
# Directory Structure for Notes App Project
## Project Overview
This document outlines the recommended directory structure for a "Notes App" project. The structure prioritizes clear separation of concerns, scalability, and adherence to the `io8` project principles. It assumes a full-stack application with distinct backend and frontend components.
## Core Principles Applied
### Strict Structure Adherence
The project will maintain the exact directory structure mandated by `io8`, with `backend/` and `frontend/` directories for code separation, and root-level configuration files. All agent-specific outputs and project documents will be centralized within the `cloned base project/.sureai/` directory.
### Code Separation
Backend and frontend codebases are strictly separated into `backend/` and `frontend/` directories, respectively. This promotes independent development, deployment, and technology choices for each layer.
### Root Level Files
Essential project-wide configuration files such as `Dockerfile.backend`, `Dockerfile.frontend`, `docker-compose.yml`, and `deployment_config.yml` are placed at the project root for easy access and consistent environment setup.
### Hidden Agent Outputs
All intermediate files and specific outputs generated by various `io8` agents (e.g., this document, B.MAD agent outputs, Analyst agent outputs) will be prefixed with a dot (`.`) and stored within the `cloned base project/.sureai/` directory to keep the main project structure clean.
### Visible Documents
Key project documents like `analysis_document.md`, `requirements_document.md`, `architecture_document.md`, etc., will also reside in the `cloned base project/.sureai/` directory, without a dot prefix, for easy visibility and access by project stakeholders.
## Detailed Directory Structure Plan
The following structure is planned for the "Notes App" project. This is a documentation of the intended ideal state, building upon a cloned base project.
```

```
## Workflow Integration
This directory structure sets the foundation for subsequent agent operations:
* **Analyst Agent:** Will populate `analysis_document.md` and `requirements_document.md` within `cloned base project/.sureai/`.
* **Architect Agent:** Will define the system architecture and tech stack, populating `architecture_document.md` and `tech_stack_document.md` within `cloned base project/.sureai/`.
* **PM/Scrum Master Agents:** Will create `prd_document.md`, `project_plan.md`, `tasks_list.md`, and `sprint_plan.md` in `cloned base project/.sureai/`.
* **Developer Agent:** Will create the actual backend and frontend code within the `backend/` and `frontend/` directories, following the architecture and requirements.
* **DevOps Agent:** Will define and create the necessary root-level configuration files: `Dockerfile.backend`, `Dockerfile.frontend`, `docker-compose.yml`, and `deployment_config.yml`.
This structure ensures a systematic and organized approach to developing the "Notes App".

## DIRECTORY STRUCTURE UPDATE - 2025-10-02 06:08:11
# Directory Structure for Notes App Project
This document outlines the expected and standardized directory structure for the "Notes App" project. This structure is designed to ensure consistency, separation of concerns, and efficient development, deployment, and maintenance.
**Note:** This is a documentation of the intended structure. For base projects, this agent *only documents* the existing or desired structure and *does not create* any files or directories itself. Subsequent agents (like the Developer or DevOps agents) will populate these directories and create necessary configuration files.

**Customizations for Notes App Project:**
* **`backend/`**: This directory is designated for the server-side application logic of the Notes App. It will contain the API endpoints necessary for managing notes (creating, retrieving, updating, deleting), handling user authentication, and interacting with the database where notes are stored. Typical contents might include application code, database models, business logic services, and API controllers.
* **`frontend/`**: This directory will host all client-side code responsible for the user interface of the Notes App. This includes UI components (e.g., a note list, note editor), styling, and client-side logic to communicate with the `backend/` API to display, edit, and save notes. This could be a Single Page Application (SPA) built with frameworks like React, Vue, or Angular.
* **Configuration Files**: The root-level configuration files (`Dockerfile.backend`, `Dockerfile.frontend`, `docker-compose.yml`, `deployment_config.yml`) will be tailored specifically to define, build, run, and deploy the Notes App services. `docker-compose.yml` will likely include services for the backend, frontend, and a database (e.g., PostgreSQL, MongoDB) required by the Notes App.

## ARCHITECTURE UPDATE - 2025-10-02 06:15:22
# Architecture Document
Generated: 2025-10-02T[CURRENT_TIMESTAMP]
## System Overview
The "Notes App" is a full-stack web application designed for personal note management. It enables users to securely register, log in, and perform CRUD (Create, Read, Update, Delete) operations on their notes. Phase 2 enhancements include advanced features such as search, filtering, rich text editing, and tagging for improved organization. The frontend is built with Angular, leveraging the Clarity Design System from the base project for a consistent and intuitive user interface. The backend will expose a RESTful API to manage user authentication, notes, and associated metadata, ensuring data persistence and security.
## Architecture Pattern
### Client-Server Architecture
The application will follow a classic client-server architecture, where the Angular frontend acts as the client consuming services provided by a dedicated backend API.
### Layered Backend Architecture
The backend will implement a layered architecture to ensure separation of concerns, maintainability, and scalability:
1. **Presentation Layer (API/Controllers):** Handles HTTP requests, authentication, request parsing, and response formatting. Exposes RESTful endpoints.
2. **Service/Business Logic Layer:** Contains the core business logic, orchestrates operations, and applies business rules (e.g., password policies, note ownership validation).
3. **Data Access Layer (Repository/ORM):** Abstracts database interactions, performing CRUD operations, handling data mapping, and managing transactions.
## Component Design
### Frontend (Angular - Leveraging Clarity Boilerplate)
* **Auth Module:** Encapsulates components for user registration, login, and potentially password reset/change. Includes `AuthService` for API interaction and `AuthGuard` for route protection.
* **Notes Module:** Manages all note-related functionalities. Contains components for:
* `NotesListComponent`: Displays a paginated/filtered list of notes. Incorporates search and filter UI.
* `NoteDetailComponent`: Displays a single note's content.
* `NoteEditorComponent`: Used for creating and editing notes. Integrates a rich text editor and tag input.
* **Core Module:** (From boilerplate) Provides singleton services like `AuthenticationService` (managing JWT tokens, user state), `ErrorInterceptor` (for global API error handling), and `LoggerService`.
* **Shared Module:** (From boilerplate) Contains reusable UI components (e.g., custom card, loader, pagination controls), directives, and pipes that are used across multiple feature modules. Will include components related to tag display (e.g., Clarity labels).
* **Layout Components:** (From boilerplate) `HeaderComponent` (with user profile/logout), `SidebarComponent` (for navigation to notes list, future dashboards).
### Backend (RESTful API)
* **Authentication Service/Controller:** Endpoints for `/api/auth/register`, `/api/auth/login`, `/api/auth/logout`. Handles user creation, password hashing, JWT generation, and token validation.
* **User Service/Controller:** Manages user-specific data (e.g., `/api/users/{id}`). Primarily for internal use or administrative purposes, potentially for user profile updates.
* **Notes Service/Controller:** Provides CRUD operations for notes. Endpoints like `/api/notes`, `/api/notes/{id}`. Includes logic for search, filter, and tagging notes based on user ownership.
* **Tag Service/Controller:** (If implemented as a separate entity) Manages user-defined tags. Endpoints like `/api/tags`.
* **Data Access Layer:** Interfaces with the chosen database via an ORM (Object-Relational Mapper). Maps database entities to application objects (e.g., `User` entity, `Note` entity, `Tag` entity).
## Data Architecture
**Database Type:** Relational Database (e.g., PostgreSQL).
### Entities and Relationships:
1. **User:**
* `id` (Primary Key, UUID)
* `username` (Unique, String)
* `password_hash` (String, for securely stored password)
* `email` (Unique, String, Optional if username is primary identifier for login)
* `created_at` (Timestamp)
* `updated_at` (Timestamp)
* *Relationship:* One User has many Notes.
2. **Note:**
* `id` (Primary Key, UUID)
* `user_id` (Foreign Key to User.id, Required)
* `title` (String)
* `content` (Text type, to accommodate rich text/Markdown)
* `created_at` (Timestamp)
* `updated_at` (Timestamp)
* *Relationship:* One Note belongs to one User. Many-to-many with Tags (via `Note_Tag` join table).
3. **Tag:** (For Phase 2 advanced tagging)
* `id` (Primary Key, UUID)
* `user_id` (Foreign Key to User.id, Required - Tags are user-specific)
* `name` (String, Unique per user)
* *Relationship:* Many-to-many with Notes (via `Note_Tag` join table).
4. **Note_Tag (Join Table):**
* `note_id` (Foreign Key to Note.id)
* `tag_id` (Foreign Key to Tag.id)
* *Composite Primary Key:* (`note_id`, `tag_id`)
### Data Flow:
* Frontend sends HTTP requests (JSON payload) to backend API.
* Backend API processes requests, interacts with the database via DAL/ORM.
* Database stores and retrieves data.
* Backend sends HTTP responses (JSON payload) back to the frontend.
* Frontend processes responses, updates UI, and displays data.
## API Design
RESTful API adhering to standard HTTP methods and resource-based URLs. JSON will be the primary data exchange format. All user-specific endpoints will require authentication.
### Authentication Endpoints (`/api/auth`)
* `POST /api/auth/register`: Create a new user account.
* Request: `{ username, email, password }`
* Response: `{ userId, username }` (or JWT token directly)
* `POST /api/auth/login`: Authenticate user and issue JWT.
* Request: `{ username, password }`
* Response: `{ accessToken, refreshToken (optional), expiresIn }`
* `POST /api/auth/logout`: Invalidate current user session/token.
* Request: (Header: `Authorization: Bearer <token>`)
* Response: `{ message: "Logged out successfully" }`
### Notes Endpoints (`/api/notes`)
* `GET /api/notes`: Retrieve all notes for the authenticated user. Supports query parameters for search and filter.
* Query Params: `?search={keyword}&tags={tag1,tag2}&startDate={date}&endDate={date}&page={num}&limit={num}`
* Response: `[{id, title, contentSnippet, tags, createdAt, updatedAt}]`
* `POST /api/notes`: Create a new note for the authenticated user.
* Request: `{ title, content, tags: [tag_names] }`
* Response: `{id, title, content, tags, createdAt, updatedAt}`
* `GET /api/notes/{id}`: Retrieve a specific note by ID for the authenticated user.
* Response: `{id, title, content, tags, createdAt, updatedAt}`
* `PUT /api/notes/{id}`: Update an existing note by ID for the authenticated user.
* Request: `{ title, content, tags: [tag_names] }`
* Response: `{id, title, content, tags, createdAt, updatedAt}`
* `DELETE /api/notes/{id}`: Delete a specific note by ID for the authenticated user.
* Response: `{ message: "Note deleted successfully" }`
### Tags Endpoints (`/api/tags`) - For user-specific tag management
* `GET /api/tags`: Retrieve all tags for the authenticated user.
* Response: `[{id, name}]`
* `POST /api/tags`: Create a new tag for the authenticated user.
* Request: `{ name }`
* Response: `{id, name}`
* `DELETE /api/tags/{id}`: Delete a specific tag by ID for the authenticated user.
* Response: `{ message: "Tag deleted successfully" }`
## Security Architecture
* **User Authentication:** JWT (JSON Web Tokens) will be used for stateless authentication. Access tokens will be short-lived, and optionally refresh tokens can be used for seamless re-authentication.
* **Password Hashing:** User passwords will be hashed using a strong, adaptive hashing algorithm (e.g., bcrypt) with a sufficient salt value before storage in the database.
* **Data in Transit:** All communication between the frontend and backend will be secured using HTTPS (TLS/SSL encryption).
* **Authorization:** Backend API endpoints will implement authorization checks to ensure that a user can only access, modify, or delete their own notes and tags. This will be enforced by validating the JWT and verifying the `userId` associated with the request against the `userId` linked to the resource.
* **Input Validation & Sanitization:** Both frontend and backend will perform rigorous input validation. Frontend validation provides immediate feedback, while backend validation is critical for security to prevent common vulnerabilities like SQL Injection, XSS (Cross-Site Scripting), and other data integrity issues. Rich text content will require careful sanitization to prevent XSS.
* **Rate Limiting:** Authentication endpoints (`/api/auth/login`, `/api/auth/register`) will implement rate limiting to mitigate brute-force and denial-of-service attacks.
* **CORS (Cross-Origin Resource Sharing):** The backend API will be configured to correctly handle CORS policies, allowing requests only from the trusted frontend application origin.
## Scalability Considerations
* **Stateless Backend:** The use of JWT for authentication will keep the backend stateless, allowing for easy horizontal scaling of API instances.
* **Database Optimization:** Use of a robust relational database (PostgreSQL) with proper indexing on `userId`, `createdAt`, `updatedAt`, `title`, and `content` (for search) will ensure efficient query performance even with large datasets.
* **Caching:** For future scalability, a caching layer (e.g., Redis) could be introduced to cache frequently accessed notes or search results, reducing database load.
* **Containerization:** The application components (frontend, backend, database) will be containerized using Docker, facilitating consistent deployment and scaling in environments like Kubernetes or Docker Swarm.
* **Modular Frontend:** Angular's modular structure and lazy-loading for feature modules contribute to a scalable and performant frontend by reducing initial bundle size.

## ARCHITECTURE UPDATE - 2025-10-02 06:15:56
# Architecture Document
Generated: 2025-10-02T06:14:03.000000
## System Overview
The "Notes App" is a full-stack web application designed for personal note management. It enables users to securely register, log in, and perform CRUD (Create, Read, Update, Delete) operations on their notes. Phase 2 enhancements include advanced features such as search, filtering, rich text editing, and tagging for improved organization. The frontend is built with Angular, leveraging the Clarity Design System from the base project for a consistent and intuitive user interface. The backend will expose a RESTful API to manage user authentication, notes, and associated metadata, ensuring data persistence and security.
## Architecture Pattern
### Client-Server Architecture
The application will follow a classic client-server architecture, where the Angular frontend acts as the client consuming services provided by a dedicated backend API.
### Layered Backend Architecture
The backend will implement a layered architecture to ensure separation of concerns, maintainability, and scalability:
1. **Presentation Layer (API/Controllers):** Handles HTTP requests, authentication, request parsing, and response formatting. Exposes RESTful endpoints.
2. **Service/Business Logic Layer:** Contains the core business logic, orchestrates operations, and applies business rules (e.g., password policies, note ownership validation).
3. **Data Access Layer (Repository/ORM):** Abstracts database interactions, performing CRUD operations, handling data mapping, and managing transactions.
## Component Design
### Frontend (Angular - Leveraging Clarity Boilerplate)
* **Auth Module:** Encapsulates components for user registration, login, and potentially password reset/change. Includes `AuthService` for API interaction and `AuthGuard` for route protection.
* **Notes Module:** Manages all note-related functionalities. Contains components for:
* `NotesListComponent`: Displays a paginated/filtered list of notes. Incorporates search and filter UI.
* `NoteDetailComponent`: Displays a single note's content.
* `NoteEditorComponent`: Used for creating and editing notes. Integrates a rich text editor and tag input.
* **Core Module:** (From boilerplate) Provides singleton services like `AuthenticationService` (managing JWT tokens, user state), `ErrorInterceptor` (for global API error handling), and `LoggerService`.
* **Shared Module:** (From boilerplate) Contains reusable UI components (e.g., custom card, loader, pagination controls), directives, and pipes that are used across multiple feature modules. Will include components related to tag display (e.g., Clarity labels).
* **Layout Components:** (From boilerplate) `HeaderComponent` (with user profile/logout), `SidebarComponent` (for navigation to notes list, future dashboards).
### Backend (RESTful API)
* **Authentication Service/Controller:** Endpoints for `/api/auth/register`, `/api/auth/login`, `/api/auth/logout`. Handles user creation, password hashing, JWT generation, and token validation.
* **User Service/Controller:** Manages user-specific data (e.g., `/api/users/{id}`). Primarily for internal use or administrative purposes, potentially for user profile updates.
* **Notes Service/Controller:** Provides CRUD operations for notes. Endpoints like `/api/notes`, `/api/notes/{id}`. Includes logic for search, filter, and tagging notes based on user ownership.
* **Tag Service/Controller:** (If implemented as a separate entity) Manages user-defined tags. Endpoints like `/api/tags`.
* **Data Access Layer:** Interfaces with the chosen database via an ORM (Object-Relational Mapper). Maps database entities to application objects (e.g., `User` entity, `Note` entity, `Tag` entity).
## Data Architecture
**Database Type:** Relational Database (e.g., PostgreSQL).
### Entities and Relationships:
1. **User:**
* `id` (Primary Key, UUID)
* `username` (Unique, String)
* `password_hash` (String, for securely stored password)
* `email` (Unique, String, Optional if username is primary identifier for login)
* `created_at` (Timestamp)
* `updated_at` (Timestamp)
* *Relationship:* One User has many Notes.
2. **Note:**
* `id` (Primary Key, UUID)
* `user_id` (Foreign Key to User.id, Required)
* `title` (String)
* `content` (Text type, to accommodate rich text/Markdown)
* `created_at` (Timestamp)
* `updated_at` (Timestamp)
* *Relationship:* One Note belongs to one User. Many-to-many with Tags (via `Note_Tag` join table).
3. **Tag:** (For Phase 2 advanced tagging)
* `id` (Primary Key, UUID)
* `user_id` (Foreign Key to User.id, Required - Tags are user-specific)
* `name` (String, Unique per user)
* *Relationship:* Many-to-many with Notes (via `Note_Tag` join table).
4. **Note_Tag (Join Table):**
* `note_id` (Foreign Key to Note.id)
* `tag_id` (Foreign Key to Tag.id)
* *Composite Primary Key:* (`note_id`, `tag_id`)
### Data Flow:
* Frontend sends HTTP requests (JSON payload) to backend API.
* Backend API processes requests, interacts with the database via DAL/ORM.
* Database stores and retrieves data.
* Backend sends HTTP responses (JSON payload) back to the frontend.
* Frontend processes responses, updates UI, and displays data.
## API Design
RESTful API adhering to standard HTTP methods and resource-based URLs. JSON will be the primary data exchange format. All user-specific endpoints will require authentication.
### Authentication Endpoints (`/api/auth`)

* Request: `{ title, content, tags: [tag_names] }`
* Response: `{id, title, content, tags, createdAt, updatedAt}`
* `DELETE /api/notes/{id}`: Delete a specific note by ID for the authenticated user.
* Response: `{ message: "Note deleted successfully" }`
### Tags Endpoints (`/api/tags`) - For user-specific tag management
* `GET /api/tags`: Retrieve all tags for the authenticated user.
* Response: `[{id, name}]`
* `POST /api/tags`: Create a new tag for the authenticated user.
* Request: `{ name }`
* Response: `{id, name}`
* `DELETE /api/tags/{id}`: Delete a specific tag by ID for the authenticated user.
