Where does elastic beanstalk t2 server store my node.js app files?
node.jsAmazon Ec2Amazon Elastic-Beanstalknode.js Problem Overview
From an architecture perspective I'm trying to get a better understand of how and where files deployed to eb (t2) server are stored.
I see some .zip files in s3 that show when I upload something via the eb interface, though how/where exactly does this get end up on my ec2(t2) server?
node.js Solutions
Solution 1 - node.js
It's in the /tmp/deployment/application folder during deployment and the moved to /var/app/current afterward.
In case you search them, the node logs are in /var/log/nodejs/nodejs.log and the application will bind to 8081 no matter what PORT environment variable you set in the Environment Variables in the console.
Solution 2 - node.js
The top answer seems to be still working in November of 2020 for node app (nuxt app in my case)
/var/app/current
Solution 3 - node.js
As a more general answer (not node.js-specific), check eb-engine.log from your Elastic Beanstalk environment.
Where are the logs? In Elastic Beanstalk's online interface in the sidebar of your environment.

Interpretation:
app_source_bundlewas uploaded to/opt/elasticbeanstalk/deployment/initiallyapp_source_bundlewas extracted to/var/app/staging/
If Elastic Beanstalk deployment is successful, you can find the running app's code in /var/app/current (as Manuel pointed out).
Solution 4 - node.js
/var/app/current may be outdated. It doesn't exist on my instance.
As said there https://stackoverflow.com/questions/27973619/i-cant-find-my-web-app-when-i-ssh-to-my-aws-elastic-beanstalk-instance, for python the app is in /opt/python/bundle/2/app/
Otherwise use find to search for the location (look at the link).
