systemprompt-generator

Static site generation and content publishing orchestrator for systemprompt.io. Coordinates domain services to generate prerendered HTML pages, sitemaps, RSS feeds, and optimized assets.

Overview

This application-layer crate orchestrates the full content publishing pipeline:

1. Content Ingestion - Fetches and processes content from sources
2. Prerendering - Generates static HTML for all content pages
3. Asset Organization - Copies and organizes CSS, JS, fonts, and images
4. Feed Generation - Creates sitemaps and RSS feeds for SEO

Architecture Notes

This crate follows the application layer pattern:

• Orchestration only - No business logic; delegates to domain services
• Read-only domain access - Uses ContentRepository for data fetching
• Job interface - Jobs implement systemprompt_traits::Job for scheduling
• Template delegation - Uses TemplateRegistry from domain layer
• Config via models - Uses Config::get() instead of direct env::var()

Installation

Add to your Cargo.toml:

[dependencies]
systemprompt-generator = "0.0.1"
