How to solve node.js “JavaScript heap out of memory” problem?

I'm running a node.js service on my Ubuntu 16.04 server. I came across a problem recently, where I get this error message: "UFATAL ERROR: CALL_AND_RETRY_LAST Allocation failed - JavaScript heap out of memory".

Now, I read here on SO that I can use something like: node --max-old-space-size=4096 yourFile.js to fix this, however I don't start my service like that, I use supervisorctl start <servicename> to start the service. So, I am not sure how can I solve th problem in my case. Can you suggest what should I do?

supervisorctl use of a configuration file. It should be placed somewhere like : 

/etc/supervisor/conf.d/myapi.conf

and look like : 

[program:my-api]
command=node /home/myuser/myapi/app.js
autostart=true
autorestart=true
environment=NODE_ENV=production
stderr_logfile=/var/log/myapi.err.log
stdout_logfile=/var/log/myapi.out.log
user=myuser

add the running option inside of it :

[program:my-api]
command=node --max-old-space-size=4096 /home/myuser/myapi/app.js
autostart=true
autorestart=true
environment=NODE_ENV=production
stderr_logfile=/var/log/myapi.err.log
stdout_logfile=/var/log/myapi.out.log
user=myuser
