How to properly restart nodemon server

Question

When I run a nodejs server with the following command:

"start": "nodemon --max-old-space=8192 ./src/app.js --exec babel-node"

and I change anything in the code, nodemon automatically reloads the code and restarts the server with the following message.

[nodemon] restarting due to changes...
[nodemon] starting `babel-node --max-old-space=8192 ./src/app.js`

How do I restart the server manually the same way?

Or in other words: What do I write in the package.json scripts "restart" command to simulate the same behaviour that is done by nodemon automatically?

Thanks

Solution 1

The purpose of nodemon is to listen changes of the file and restart the server. If you want manually to restart the server then you no need to use nodemon, you can use just node command.

The below code would serve the purpose.

{
    "scripts": {
        "start": "node ./src/app.js",
        "restart": "kill -9 $(ps aux | grep '\snode\s' | awk '{print $2}') && node ./src/app.js "
    },
}

Solution 2

As stated in the documentation, you can restart manually by typeing rs in the console where nodemon is running.
There is no external command to trigger a restart from a different process.
One workaround would be to trigger a restart by simulating a change of a file.
A simple touch on a watched file is enough. So you could write a npm script that touches one of the watched files.

"restart": "touch app.js"
