after installing 'npm install webpack-dev-server -g' not able to start expressjs project.
I am using below script:
"scripts": { "start": "run-p watch dev-server", "watch": "webpack --config webpack.config.js --watch --mode development", "dev-server": "BABEL_ENV=dev nodemon --exec 'babel-node' src/server/index.js --config nodemon.json" }
run-p
command. Are you missing another dependency – perhaps npm-run-all? - Jonathan Lonowski
