Forever + Nodemon running together
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.
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.
