Running your application using the Node's command-line tool may not seem like a redundant task. However, when continuously developing your application, you will soon notice that you stop and start your application server quite often. To help with this task, there is a common tool called Nodemon. Nodemon is a Node.js command-line tool that functions as a wrapper to the simple node command-line tool, but watches for changes in your application files. When Nodemon detects file changes, it automatically restarts the node server to update the application. To use Nodemon, you will need to modify your project's package.json file, as follows:
{
"name": "MEAN",
"version": "0.0.11",
"scripts": {
"tsc": "tsc",
"tsc:w": "tsc -w",
"app": "node server",
"app:dev": "npm run lint && npm run app",
"nodemon": "nodemon -w app -w config -w server.js --exec npm run app:dev",
"start": "concurrently \"npm run webpack\" \"npm run nodemon\",
"postinstall": ...
