nodejs forever : How to run my npm application

Question

Right now i am runnign my nodejs application as `npm start`. i want to run it in background. I found `forever` package for this but dont know how can i run a application that i usually run as `npm start`. So how can i run it using `forever` ? I follow this SO but getting this error: ``` ENVIRONMENT=production forever start app.js warn: --minUptime not set. Defaulting to: 1000ms warn: --spinSleepTime not set. Your script will exit if it does not stay up for at least 1000ms info: Forever processing file: app.js ``` apart of this Is there any other better way to run nodejs in background ?

Accepted Answer

You are doing it right.

The warnings are just reminding you that some essential information is missing, so it assigns the defaults. To be exact, if your script crashes/exits sooner than a second after start, forever will exit as well.

If you would like to get rid of those warnings:

```
forever start --minUptime 1000 --spinSleepTime 1000 app.js 
```

Furthermore, you can open the `package.json` file, find the:

```
  "scripts": {
    "start": "node app.js"
  },
```

and change it to:

```
  "scripts": {
    "start": "forever start --minUptime 1000 --spinSleepTime 1000 app.js",
    "stop":  "forever stop app.js"
  },
```

Now you can use `npm start` and it will invoke `forever` automatically.
