Everytime you change a ICS file you have to compile it. Following command compiles several ICS files in different directories::
iced -c *.iced ./routes/*.iced ./lib/domain/*.iced
You can put this command to your package.json:
"start": "node app.js",
"prepublish": "iced -c *.iced ./routes/*.iced ./lib/domain/*.iced"
And now you can type the short command:
for compiling, or:
npm install; npm start
for compiling and starting.
