Development - how to build
You should be able to build the nodes executing
npm installnpm run-script build
To test them I use docker and mount the dist directory to /data/nodes like this
docker run -it --name tuya-test-container -p 1880:1880 -v $(pwd)/dist/lib:/data/nodes nodered/node-red-docker. Be aware that by using this shortcut you have to ensure the dependencies of the nodes inside the container have to be installed manually
docker exec -it tuya-test-container bash -c 'cd /data && npm i email@example.com --upgrade'.
