Swaggerific

Swaggerific is an open-source application that functions as a client for REST APIs, using Swagger or OpenAPI specifications to generate its user interface. The tool is developed in Java and JavaFX, providing a platform to interact with web services through existing API documentation.

• Specification loading. This function allows importing Swagger or OpenAPI JSON documents from a URL or local files. The system parses the document structure and reconstructs the complete API definition, including endpoints, parameters, and data models.
• Endpoint tree navigation. It presents a hierarchical view organized by paths and HTTP methods in the side panel. Each endpoint is displayed with its corresponding method (GET, POST, PUT, DELETE), facilitating quick access to specific operations.
• HTTP request execution. It allows sending requests to configured endpoints with all compatible HTTP methods. The system automatically manages required headers and prepares the request body according to the API specifications.
• JSON editor with syntax highlighting. It incorporates a specialized editor for composing request bodies in JSON format. The feature applies differentiated colors for keys, values, and structures, improving code readability.
• Character auto-completion. Automatically complements braces, brackets, and quotes while typing in the JSON editor. This feature maintains correct syntax and reduces formatting errors in requests.
• Formatted response display. It presents server responses with indentation and organized structure for JSON and XML. The system automatically detects the content type and applies the corresponding formatting.
• Raw response view. Displays the complete HTTP response including headers and the unprocessed body. This view is used for detailed analysis of the communication with the server.
• Form fields for parameters. Generates input interfaces based on the parameter schemas defined in the OpenAPI specification. The fields adapt to the data types expected for each parameter.
• Dropdown list selection. Implements selection controls for parameters with predefined enumerated values. Users choose from valid options without needing to manually enter the values.
• Error handling with descriptive messages. Detects and classifies different types of errors during application operation. It provides specific messages that indicate the nature of the problem and possible solutions.
• JavaFX interface with responsive design. Builds the graphical interface using JavaFX components with modern styles. The layout of elements adapts to different window sizes while maintaining full functionality.
• Architecture based on SOLID principles. Organizes the code using a structure that clearly separates the user interface from the HTTP service logic. This separation facilitates maintenance and the extension of functionalities.

Swaggerific's development began as an alternative to existing API clients, created by Özkan Pakdil. The project was initiated using Java 17 and JavaFX for the graphical interface implementation. The architecture follows solid design principles with a clear separation between interface components and service logic.
