SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Prolog-based REST API development often requires boilerplate for routing and JSON handling; this Skill provides a structured approach to build a CRUD API using SWI-Prolog's built-in HTTP server, JSON support, and optional SQLite persistence.

Core Features & Use Cases

  • Declarative HTTP routing with http_handler predicates to map routes to handlers.
  • JSON encoding/decoding via Prolog dicts for seamless request/response handling.
  • In-memory CRUD using assert/retract or optional persistent storage with SQLite.
  • Session management example illustrating user authentication flow and stateful interactions.
  • Clear mapping to Express.js concepts for developers transitioning from Node.js to Prolog.

Quick Start

Run the Prolog server with server(8080) to start listening for CRUD API requests.

FAQPage Schema
How do I build a REST API in SWI-Prolog?

To build a REST API in SWI-Prolog, use this Skill's structured approach for declarative HTTP routing, JSON dict handling, and optional SQLite persistence to generate CRUD endpoints. It reduces boilerplate by mapping routes directly to handler predicates.

Can I use SQLite for persistent storage in a Prolog CRUD app?

Yes, you can use SQLite for persistent storage in a Prolog CRUD app. This Skill supports optional SQLite persistence alongside in-memory data management using dynamic predicates with assert and retract for state handling.

How do I handle JSON requests and responses in SWI-Prolog?

Handle JSON requests and responses in SWI-Prolog by using built-in JSON libraries to encode and decode Prolog dicts. This Skill automates that conversion process for seamless request and response payload management in HTTP handlers.

Does this Prolog API Skill map to Express.js concepts?

Yes, this Prolog API Skill explicitly maps to Express.js concepts. It provides clear analogies for developers transitioning from Node.js, illustrating how SWI-Prolog HTTP routing and session management correspond to Express patterns.

How do I implement session management and user authentication in SWI-Prolog?

Implement session management and user authentication in SWI-Prolog using the provided session examples. This Skill illustrates stateful interactions and user authentication flows within the HTTP server environment to maintain secure client state.

What's the best way to prototype a backend quickly in SWI-Prolog?

The best way to prototype a backend quickly in SWI-Prolog is using this Skill's automated CRUD API generation. Run the server with server(8080) to immediately start listening for RESTful API requests with minimal routing setup.
