REST API Design
Relevant source files
The following files were used as context for generating this wiki page:
The REST API design for the analiza-este-lovable-tamv project is primarily structured around an integration with Supabase, which provides an auto-generated RESTful interface based on the underlying PostgreSQL database schema. This system allows the frontend to perform CRUD (Create, Read, Update, Delete) operations and manage authentication via a standardized API layer.
The architecture focuses on a client-server model where the frontend interacts with Supabase services. The API design is reflected in the TypeScript type definitions that ensure data consistency between the database and the application UI.

Database Schema and API Mapping
The REST API endpoints are directly mapped to the database tables defined within the Supabase public schema. The Database interface defines the structure of the data that can be queried or modified through the API.
Table Structures
The following table summarizes the data structures that define the API resource models:
| Table Name | Field | Type | Description |
|---|---|---|---|
| profiles | id | uuid | Primary key (unique identifier) |
| first_name | text | User's first name (Optional) | |
| last_name | text | User's last name (Optional) | |
| avatar_url | text | URL to user's profile image |

Data Flow and Integration
The application utilizes a centralized client to communicate with the REST API. This client handles the authentication headers and the base URL for API requests.
This diagram illustrates the flow from the client application through the Supabase abstraction layer to the persistent storage.

Client-Side API Interaction
The API is accessed through a configured Supabase client. This client is initialized with the project's specific URL and anonymous key, providing a typed interface for all API calls.
API Client Initialization
The client is exported for use across the application, ensuring that all modules use the same configuration and authentication context.

Implementation Example
The application logic uses these types to interact with the API resources. For instance, when querying the profiles table, the API returns objects matching the Row definition:
export type Tables<
PublicTableNameOrOptions extends
| keyof (Database["public"]["Tables"] & Database["public"]["Views"])
| { schema: keyof Database },
TableName extends PublicTableNameOrOptions extends { schema: keyof Database }
? keyof (Database[PublicTableNameOrOptions["schema"]]["Tables"] &
Database[PublicTableNameOrOptions["schema"]]["Views"])
: never = never
> = ...

Responsive API Presentation
The UI components interact with the API data and adapt based on the device context. The useMobile hook is an example of how the application manages state that may affect how API data is requested or displayed.
The sequence shows how the application determines device state before or during data fetching operations.

Error Handling and Validation
The API design incorporates strict TypeScript checks to prevent invalid data from being sent to the server. The TablesUpdate and TablesInsert types define exactly which fields are required or optional during write operations.
- Insert Operations: Requires fields not marked as nullable or having defaults.
- Update Operations: All fields are optional to allow partial updates.

The REST API design for this project leverages Supabase to provide a type-safe, scalable, and standardized interface. By mapping database schemas directly to TypeScript interfaces, the project ensures that the frontend and backend remain synchronized, reducing runtime errors and improving development velocity.
