Forever + Nodemon running together

Is there any way to have both of this packages running together?

So basically I want to have best from both worlds. Running server automatically (and restarting when there is an error) and also automatic updates when there is .js file change happening.

You should run something like this

forever start -c nodemon app.coffee

Toxa was on the right track, the issue that cfogelberg raised is valid, but to avoid that issue you can do the following:

forever -c "nodemon --exitcrash" app.js

this makes sure nodemon actually exits (rather than giving you the "app crashed" message) and then forever picks it up again.

In forever --help this -c specifies a command to run otherwise it defaults node. Without -c results in the error that is mention in the comments to this answer.

There is an entry about it in the nodemon FAQ:

I have not found a way of getting both packages running together. I tried to do @toxa's technique, but when my node.js app threw an exception nodemon would not automatically restart it, instead outputting an error message to the forever log:

nodemon] app crashed - waiting for file changes before starting...

However, forever has a -w option and the following command is effectively the same as if I'm running nodemon and forever together:

forever start -w my-app.js

The downside of forever -w versus nodemon: forever does not have a --delay option, so my server gets restarted once for each file that is changed.

I prefer a combo of what Toxa and Jubair suggest.

forever start -c nodemon app.coffee --exitcrash

If you need to pass arguments:

forever start -c "nodemon --harmony" app.js --exitcrash

I'm using forever-service . . .

This is what worked for me. It does the following: everytime a json or raml file in the applications dist/assets folder is modified, wait 10 seconds and then restart the node app (server.js script):

$ forever-service install raml --script server.js -f " -c nodemon" -o " --delay 10 --watch dist/assets -e json,raml --exitcrash" -e "PATH=/usr/local/bin:$PATH"

Then I can run:

$ service raml start|stop|restart|status

I can also have the service start on server reboot with the chkconfig utility:

$ chkconfig --add raml
$ chkconfig raml on

when using in the package.json use single quotes to make nodemon --existcrash as a single argument. "start": "forever -c 'nodemon --exitcrash' server.js"

Output: app_1 | [nodemon] app crashed app_1 | error: Forever detected script exited with code: 1 app_1 | error: Script restart attempt #1 app_1 | [nodemon] 1.19.4 app_1 | [nodemon] to restart at any time, enterrsapp_1 | [nodemon] watching dir(s): *.* app_1 | [nodemon] watching extensions: js,mjs,json app_1 | [nodemon] startingnode /app/server.js` app_1 | app is running on port 3000
