# Rentgen Browser Extension - Docker Build
#
# Usage:
#   Build and extract artifacts directly:
#     docker buildx build . --output artifacts
#
#   Build with tests (typecheck + lint):
#     docker build --build-arg RUN_TESTS=true -t rentgen .
#
#   Or traditional build (creates full development environment):
#     docker build -t rentgen .
#     docker run --rm rentgen ls -lh /app/web-ext-artifacts/
#
#   Run commands in the container:
#     docker run --rm rentgen npm run build:chrome
#     docker run --rm rentgen npm run typecheck
#
#   Run extension in Firefox (headless):
#     docker build --target runtime -t rentgen-run .
#     docker run --rm -it rentgen-run
#
#   Using docker-compose:
#     docker-compose up rentgen_check     # Build only
#     docker-compose up rentgen_run       # Run in Firefox

# Build stage
FROM node:lts AS builder

# Optional: run tests during build (typecheck + lint)
