Doclane Worker

NestJS worker process for Doclane PDF jobs. The app connects to Redis/BullMQ queues and S3-compatible object storage; it does not connect directly to the database.

Requirements

• Node.js 22
• pnpm
• Redis
• S3-compatible object storage
• PDF/OCR command line tools:
  • qpdf
  • fix-qdf
  • pdfinfo
  • pdftotext
  • pdftoppm
  • tesseract
  • ocrmypdf

Environment

Copy .env.example to .env and adjust the values for your Redis and S3-compatible storage.

cp .env.example .env

Application code reads environment values through config aliases such as redis.host, s3.endpoint, and pdfProcessing.ocr.enabled.

Local Development

pnpm install
pnpm start:dev

Dockerfile

Build the worker image:

docker build -t doclane-worker .

The worker container includes the PDF and OCR binaries needed by the configured processing pipeline.

Verification

After worker changes, run:

pnpm build
pnpm lint
pnpm test
