Execute Zabbix script items outside of Zabbix

[troffasky]

I am trying to write a template using Zabbix Script item to talk to Sonicwall SonicOS API.
Is there a way I can execute the script outside of Zabbix for development/testing purposes? Obviously it would have to execute it exactly as Zabbix does in order to be useful.

There is such a utility

https://www.zabbix.com/documentation/current/en/manpages/zabbix_js

You can install it the same way as regular packages. The package is called zabbix-js

Thankyou. Would be great if this was linked from the "Script items" documentation.

Any idea what the input file format is? The man page just says "the input parameter". I am guessing this would provide "obj".

I tried looking at zabbix_js.c but could not work this out.
All Hail our New AI Overlords....I asked Deepseek and it told me:

The zabbix_js tool (used for testing Zabbix JavaScript preprocessing scripts) expects the -i parameter to accept input data in JSON format. This input simulates the data passed to the preprocessing script during runtime.
...
Example:
bash

zabbix_js -s script.js -i '{"key1":"value1", "key2":123}'

And it's actually correct! It's not perfect - it hallucinated a "-I" parameter that doesn't exist. But the main thing is, I have this working, so I am happy.
