I have a TypeScript file called  server ts   The following npm scripts configures Nodemon and npm to start my app and monitor for any changes on TypeScript files    start    nodemon -e ts  --exec   npm run myapp      myapp    tsc -p    amp  amp  node server js     I already have Nodemon on dependencies  When I run npm start  it will ask Nodemon to monitor its files using the -e switch and then it calls the myapp npm script which is a simple combination of transpiling the typescript files and then starting the resulting server js  When I change the TypeScript file  because of -e switch the same cycle happens and new  js files will be generated and executed

It will depend on types of your Nodemon installation  If you install Nodemon globally by using commands  npm install nodemon --global or npm install nodemon -g   you do not have to specify any script for Nodemon in your package json file  Just executing command nodemon index js will run your project   But if you install Nodemon locally by command npm install nodemon then you have to specify the script  If you name it as start then npm run start or npm start will trigger the server to run      Absolutely no need for global installation   scripts          start    nodemon index js

If you have nodemon installed globally  simply running nodemon in your project will automatically run the start script from package json   For example    scripts        start    node src server js       From the nodemon documentation      nodemon will also search for the scripts start property in package json  as of nodemon 1 1 x
