NPM jednocześnie
// The tool is written in Node.js, but you can use it to run any commands.
npm install -g concurrently
// or if you are using it from npm scripts:
npm install concurrently --save
// Remember to surround separate commands with quotes:
concurrently "yarn run script1" "yarn run script2" "yarn run script3"
// In package.json, escape quotes:
"start": "concurrently \"command1 arg\" \"command2 arg\""
