How It Works

Vietlott blocks non-Vietnam IPs (issue #13), so crawling runs on a scheduled local runner (bin/github_data.sh) and commits updated data back to GitHub.

For architecture and runner setup, see docs/DEPLOYMENT.md.

Installation & Usage

Go crawler (recommended)

Requires Go 1.27+. Vietlott only answers Vietnamese IPs, so run it from Vietnam.

make build-crawler                       # builds bin/vietlott-crawler
./bin/vietlott-crawler status            # existing vs latest draw per product
./bin/vietlott-crawler sync --all        # fetch latest draws and backfill gaps
./bin/vietlott-crawler sync --product keno --max-draws 100
./bin/vietlott-crawler render-readme     # regenerate readme.md
./bin/vietlott-crawler render-docs       # regenerate docs/index.html

# Products: power655, power645, power535, keno, bingo18, 3d, 3d_pro

Python CLI (legacy, deprecated)

The Python crawler stays available through the PyPI package and will be removed in a future release.

# Crawl latest data
uv run vietlott-crawl keno

# Backfill missing data
uv run vietlott-missing power_655

# Available products: power_655, power_645, power_535, keno, 3d, 3d_pro, bingo18

Development Setup

git clone https://github.com/vietvudanh/vietlott-data.git
cd vietlott-data
uv sync --dev
uv run pytest
