Answer 1

You're running express 4, which has the app.listen call in a different file than app.js. The command you're looking for is nodemon bin/www (localhost and 3000 are not needed in this scenario).

In fact, you can even run nodemon with no args, and it'll read what command needs to be run from scripts.start in package.json (which express generates automatically).

Answer 2

For Express.js 4,
use nodemon
or
nodemon bin/www

Answer 3

try

npm install --save-dev nodemon

and then in package.json file keep like this

"scripts": {
    "start": "nodemon",
    "test": "echo \"Error: no test specified\" && exit 1"
  },

instead of npx nodemon, which takes more time

Answer 4

try running nodemon ./app.js 3000 or nodemon start 3000

Answer 5

Here's what I did to make nodemon update correctly:

nodemon index.js -L

The -L flag stands for legacyWatch, here's an explanation from the official doc:

In some networked environments (such as a container running nodemon reading across a mounted drive), you will need to use the legacyWatch: true which enables Chokidar's polling.

Certain child processes related to your parent process may not be closed. Try to kill all the child processes.
