The clarity !! All tutorials should be like this. From split-screening, to having individual lines of code appear rather than each character, thus is just so clear to my brain!! Bug kudos ! Subscribing

Excellent video, however I had to add the following 2 lines under docker-compose file to get things working;

Under "react-app:"
add > build: ./client

Same for "api-server:"
add > build: ./server

Thanks
