npx lerna bootstrap

# build & watch packages
npm run build && npm run watch

# create a shared network in docker
docker network create laf_shared_network --driver bridge || true

# download the app service image
docker pull lafyun/app-service:latest

# launch laf.js services
docker-compose up

# start laf.js local client
cd packages/system-client
npm run dev
# Now open in your browsers!
