fs.writeFile() writes file not relative to start.js

[virtuaCode]

Files are written relative to the path from where I execute the start.js

At the moment I can launch the server only like this:

cd /home/virtuacode/mqp-server/
exec node start.js

I would prefer to launch the server like this:

exec node /home/virtuacode/mqp-server/start.js
