Why does AppDynamics NodeJS client install Java Runtime Environment within its npm packages?

Why does AppDynamics NodeJS client install Java Runtime Environment within its npm packages? We find this to be an undesired dependency in containerised NodeJs applications. Is there a native nodejs client or plans to develop one?

Hi lukasz,

This is explained in following document

https://docs.appdynamics.com/display/PRO43/Dynamic+Language+Agent+Proxy

https://docs.appdynamics.com/display/PRO43/Node.js+Agent#Node.jsAgent-Node.jsAgentandtheJavaProxy

With 4.3, Node.Js Agent supports proxiless option with few limitations

Let us know if you have additional questions.

Thanks,

Raunak

I understand I can make the nodejs agent not use the Java proxy (

https://docs.appdynamics.com/display/PRO43/Dynamic+Language+Agent+Proxy#DynamicLanguageAgentProxy-Node.jsproxylessoption), but it will be installed anyway along the npm package? This still adds 160MB to container image. Would it be safe to delete the appdynamics-jre and appdynamics-proxy packages if the proxiless option is in use? Or is there an alternative npm package which does not include JRE and proxy dependencies?

Hi lukasz,

Yes, you can delete these two directories after the agent installation if you do not intend to use the JAVA proxy for controller communication. But, be informed that there are a few functionalities which are still not supported by native agent.

Best Regards,
