What This Plugin Adds
Section titled “What This Plugin Adds”HTML Cache is an Available, Schema-owning Capell package in the Capell Foundation product group. It ships as capell-app/html-cache and extends these surfaces: admin, frontend.
Full-page static HTML cache for Capell with dependency-indexed invalidation, scheduled stale-regeneration, and public-output safety guarantees. It stores full public HTML responses, indexes their model dependencies, and supports immediate or scheduled stale regeneration.
Administrators inspect coverage, dependency maps, and stale work, then clear, warm, or regenerate cached pages. Anonymous visitors receive cached public HTML without authoring markers or session cookies.
Evidence: capell.json, src/Http/Middleware/HtmlCacheMiddleware.php, src/Models/CachedModelUrl.php, src/Models/StaleCachedUrl.php, docs/overview.admin.md, docs/screenshots.json, src/Filament/Pages/MaintenanceCachePage.php, tests/Feature/HtmlCacheMiddlewareTest.php.
Status details:
- Status: Available
- Tier: free
- Bundle: foundation
- Composer package:
capell-app/html-cache - Namespace:
Capell\HtmlCache - Theme key: not applicable
Why It Matters
Section titled “Why It Matters”For developers: Middleware eligibility rules and dependency-indexed Actions keep cache writes, invalidation, stale claims, and atomic refresh behavior explicit and testable.
For teams: Teams can see whether important URLs are cached, recover from stale output, and diagnose unsupported node-local multi-node deployments without weakening the rule that admin and authoring details stay out of public files.

Common Pitfalls
Section titled “Common Pitfalls”- Keep required Capell packages on compatible v4 releases:
capell-app/admin,capell-app/core,capell-app/discovery-foundation,capell-app/frontend. - Run migrations before opening package resources or public routes.
- Review package configuration before production-like verification:
config/capell-html-cache.php. - Keep the host Laravel scheduler running so package-registered schedules can execute:
capell:html-cache:process-stale (package registered). - Keep public Blade and cached HTML free of authoring markers, model IDs, permissions, signed editor URLs, and lazy database queries.
- Custom write integrations must preserve invalidation for
html-cachecache tags.
Troubleshooting
Section titled “Troubleshooting”| Symptom | Likely cause | Check | Fix |
|---|---|---|---|
| Package surface is missing after install | Provider or manifest is not loaded | Confirm capell.json, package composer.json, and provider registration |
Reinstall the package, refresh Composer autoload, and clear host caches |
| Admin screen or command fails on missing table | Package migrations have not run | Check the tables listed in Data Model |
Run host migrations and rerun the focused package test |
| Background work does not run | Queue worker or declared schedule is not active | Check the jobs and scheduled commands listed in Technical Shape |
Start the queue worker or host scheduler, then run the focused command or package test |
| Public output leaks unexpected state | Render data, cache variation, or authoring boundary has regressed | Check public Blade, cache tags, and public-output safety tests | Move data loading out of Blade and rerun the package public-output tests |
Quick Start
Section titled “Quick Start”- Install the package:
