# This build script has 5 differences compared to the original build script
# 1. It enables pointer compression using ./configure --experimental-enable-pointer-compression
# 2. Set WORKDIR /app and create that directory
# 3. Set variables ENV NPM_CONFIG_LOGLEVEL=warn PATH=$PATH:/app/node_modules/.bin
# 4. Add curl, git & nano to container
# 5. does not ship with yarn
