Textify (Go)

An API gateway to parse PDFs and images via LLM-based OCR models, utilizing a Redis queue and asynchronous service workers for high-concurrency.

Prereqs: Go, PostgreSQL, Redis, Python3 with paddleocr and requests (for Paddle runner).

Install Python deps (runner):

python3 -m pip install paddleocr requests

Set env and run server:

export DATABASE_URL="postgres://user:password@localhost:5432/my_database"
export REDIS_URL="redis://localhost:6379"
export PORT=3000
go run ./src

Run worker using PaddleOCR runner:

WORKER=1 OCR_PROVIDER=paddle go run ./src

Fallback (legacy HTTP OCR service):

WORKER=1 go run ./src

That's it — enqueue with POST /textify and fetch results with GET /results/{jobId}.
