Introduction to nodemon

During development, every time you modify a file, you need to restart the express service, which is troublesome. Using nodemon, the express service can be restarted automatically after modifying the file.

1. Installation:

npm install --save-dev nodemon

2. Modify the contents of package.json:

 
"scripts": {
 
"start": "node ./bin/www",
 
"devstart": "nodemon ./bin/www"
 
}

3. Use the npm run devstart command to start the service
