Canvas Frontend Engine & Static Site Compiler

The Canvas Frontend Engine allows creative studios to design, import, compile, and host custom websites directly within Cora.

1. AI Starter Prompts Grid

The Canvas Theme Wizard includes a 5-template AI Starter Prompts Grid:

• Agency Showcase: Monochromatic portfolio with case study drawers.
• SaaS Platform: Metric counters, pricing matrices, and e-sign demos.
• Consulting / Advisory: Lead capture funnels and appointment schedulers.
• Photography Studio: Dark-room gallery, booking calendar, and client proofing.
• Custom Studio: Universal minimalist blueprint.

Prompts can be copied with 1-click and pasted into ChatGPT, Claude, or Gemini to generate production-ready HTML/Tailwind templates.

2. Automated Static Compiler Pipeline

The background compiler (cora_nextjs_build_repo) supports Next.js, Expo, Vite, and Astro:

• Automatic detection of package managers (pnpm, yarn, npm).
• Automated dependency resolution and production export (out/ or dist/).
• Single-CPU thread allocation (UV_THREADPOOL_SIZE=1, NODE_OPTIONS="--max-old-space-size=1536") to prevent resource exhaustion on shared cPanel hosting.

3. Shared Hosting Inode & Memory Resilience

• CloudLinux Inode recovery cleanses temporary ~/.npm/_cacache and build caches after every run.
• Self-healing retry logic handles directory rename locks (ENOTEMPTY) during concurrent npm extractions.

4. Lead Form Ingestion & CRM Bridge

• Ingests inbound leads from any Canvas site automatically via standard <form> tags or window.coraSubmitLead().
• Synchronizes submissions into wp_cora_leads with instant PWA push dispatch.

5. Path Traversal & 304 Caching

• Hardened asset streaming with realpath root containment preventing ../ directory traversal.
• HTTP 304 Not Modified caching with SHA-256 ETags and immutable cache headers.
