Bonescript Node App Fails to Startup as Service

Hi all,

I am writing a node.js app using bonescript and am using a systemctl service to start it on boot. I have written the service, which correctly fires the startup script but it errors out when trying to load bonescript. I can run the app from the command line just fine (node app.js) and it works, but when called from the service, it gives the following error:

Sep 25 09:42:43 brewbone brewbone[581]: at Function.Module._load (module.js:280:25)

My startup script is /user/bin/brewbone:

#!/bin/bash

nodemon /var/lib/cloud9/brewbone/app.js

The service is /lib/systemd/system/brewbone.service

[Unit]

Description=Brewbone Application

After=syslog.target

[Service]

ExecStart=/usr/bin/brewbone

[Install]

WantedBy=multi-user.target

The suspect line (output.js:1:71) is:

var b = require(“bonescript”);

Any ideas what could be causing the error?

Thanks,

What is 'nodemon'?

The service is /lib/systemd/system/brewbone.service

See examples on the board for some ideas:
root@beaglebone:/mnt# cat /lib/systemd/system/bonescript-autorun.service
[Unit]
Description=Bonescript autorun
ConditionPathExists=|/var/lib/cloud9

[Service]
WorkingDirectory=/usr/lib/node_modules/bonescript
EnvironmentFile=/etc/default/node
ExecStart=/usr/bin/node autorun.js
SyslogIdentifier=bonescript-autorun

[Install]
WantedBy=multi-user.target
root@beaglebone:/mnt# cat /etc/default/node
NODE_PATH=/usr/lib/node_modules

Most likely, you need to source /etc/default/node in your script to set
NODE_PATH.

If you have a single-file application, you might consider dropping it into
/var/lib/cloud9/autorun as the above autorun.js script will run .js files
dropped into that directory at start-up.
