Debugging Node.JS

Depending on the environment, there are different levels of debugging that can be performed on the Realtime Server

Development

You can enable debugging of the Realtime Server by adding the following entry to your usersecrets.json file:

"node-options": "--inspect=9230"

QA/Production

On QA and production, you are limited to generating heap snapshots and CPU profiles for 30 seconds at a time.

Generating a heap snapshot and CPU profile:

1. Get the process id of node: ps aux | grep node
2. Send the USR2 signal to the node process: kill -USR2 {process_id_here}

These will be created in the app directory, and named:

• scriptureforge.heapsnapshot
• profile.cpuprofile

Download them via SCP once created.
