Php Weasyprint Laravel Package

Product Decisions This Supports

• Dynamic PDF Generation: Enables on-demand PDF creation for invoices, reports, or user-generated content (e.g., "Print as PDF" buttons).
• Cost-Effective Alternative to Commercial Tools: Replaces paid services like SnappyPDF or Dompdf for high-volume use cases (e.g., e-commerce receipts, legal documents).
• Legacy System Modernization: Integrates with older PHP/Laravel apps to add PDF export without full stack rewrites.
• Compliance & Accessibility: Supports PDF/A-3b (archival) and XMP metadata for regulatory compliance (e.g., healthcare, finance).
• Queue-Based Processing: Offers timeout control for async PDF generation (e.g., background jobs in Laravel Queues).
• Security Hardening: Mitigates SSRF, command injection, and PHAR deserialization risks (critical for SaaS platforms).

When to Consider This Package

Adopt if:

• You need high-fidelity HTML-to-PDF (tables, CSS, JavaScript rendering) with WeasyPrint’s accuracy.
• Your stack is PHP 8.3+ and Laravel/Symfony (or compatible with Symfony Process).
• You require PDF/A compliance or XMP metadata (e.g., for archival or legal use).
• You can pre-install WeasyPrint (60+) on your servers (Docker, Linux, or Windows WSL).
• You prioritize security (SSRF protections, shell injection fixes).

Look elsewhere if:

• You need multi-page merging (use Dompdf or SnappyPDF).
• Your environment lacks Python/WeasyPrint (e.g., serverless cold starts).
• You require low-latency (WeasyPrint adds ~1–3s overhead vs. headless Chrome).
• You’re on PHP < 8.3 or need Windows-native support (WeasyPrint’s Windows support is limited).
• You need interactive PDFs (forms, JavaScript) beyond basic rendering.

How to Pitch It (Stakeholders)

For Executives: "This package lets us generate professional PDFs from web content—like invoices, reports, or legal docs—without third-party APIs or expensive tools. It’s secure, cost-effective, and integrates seamlessly with our Laravel stack. For example, we could add a ‘Download PDF’ button to every order confirmation, reducing support calls and improving compliance. The upfront cost is minimal (WeasyPrint installation), and it future-proofs our PDF needs for years."

For Engineers: *"PhpWeasyPrint is a SnappyPDF drop-in replacement but uses WeasyPrint for superior CSS/HTML fidelity. Key advantages:

• Type-safe API (PHP 8.3+).
• Security-first: SSRF protections, shell injection fixes, and PHAR hardening.
• Queue-friendly: Timeout control for async jobs.
• Modern features: PDF/A, XMP metadata, and WeasyPrint’s latest options. Tradeoff: Requires WeasyPrint (Python dependency), but we can containerize it. Example use case: Replace our hacky Dompdf setup for invoices with this—better rendering, same effort."*

For Security Teams: *"This package addresses critical risks:

• SSRF/LFD: Only http/https URLs are fetched by default (configurable).
• Command Injection: Uses Symfony Process’s safe execution (no shell).
• PHAR Bypass: Output paths are validated against allow-lists. Recommendation: Audit the WeasyPrint binary path and allowed schemes in production."*
