systemprompt-generator

Static site generation and content publishing orchestrator for SystemPrompt. 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:

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

`sitemap`	XML sitemap generation with chunking for large sites
`templates`	Template data preparation and HTML fragment generation

Key Types

Type	Description
`BuildOrchestrator`	Coordinates theme, TypeScript, Vite, and CSS build steps
`BuildMode`	`Development`, `Production`, or `Docker` build configuration
`PrerenderContext`	Shared context for prerendering: db pool, config, templates
`PublishContentJob`	Main job that runs the full publishing pipeline
`SitemapUrl`	URL entry for sitemap XML generation
`RssChannel` / `RssItem`	RSS feed data structures
`TemplateDataParams`	Parameters for preparing template data

Public Exports

Dependencies

Crate	Purpose
`systemprompt-database`	Database connection pool
`systemprompt-content`	Content repository and models
`systemprompt-templates`	Template registry and rendering
`systemprompt-models`	Configuration and domain types
`systemprompt-identifiers`	Typed identifiers (SourceId, ContentId)

`comrak`	Markdown to HTML

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()
