⁠POC -- High Performance Word to PDF Conversion

This project demonstrates an optimized document conversion service using a micro-services architecture with Gotenberg.

⁠🚀 Overview

The initial proof of concept relied on a local LibreOffice wrapper and showed limited performance.
This improved version leverages Gotenberg 8 running in Docker on SAP BTP (Cloud Foundry).

⁠⚡ Performance Gain

• Small documents: ~1--2 seconds\
• Large documents (100+ pages): ~6 seconds\
• Previous approach: up to 70 seconds

⁠🛠 Tech Stack

• TypeScript (Node.js / Express)
• Gotenberg 8
• Docker
• SAP BTP (Cloud Foundry)

⁠🐳 Architecture

• Converter API (Express) handles incoming requests\
• Gotenberg container performs document rendering\
• Gzip compression reduces transfer latency

⁠📡 API

• GET / → Health check\
• POST /convert → Upload .docx file (form-data: file)\
• Response: PDF (gzip compressed)

⁠🚀 Deployment

docker build --platform linux/amd64 -t your-image-name ./api
docker push your-image-name
cf push

This POC validates that a containerized micro-service architecture is suitable for high-performance document conversion in production environments.
