There is json schema validation which partly perhaps provides what you're looking for

And just in case you were not aware, the built in JSON node can also do schema validation

@vrilcode

Mustache templating is fine, but it is very restrictive. Would be great to have more flexible templating language in the core.

I agree with @TotallyInformation, this is more suited to a plugin/contrib node. There are a few existing ones:

• node-red-contrib-file-nunjucks (node) - Node-RED
• node-red-contrib-eta (node) - Node-RED
• node-red-contrib-handlebarsjs (node) - Node-RED
• node-red-contrib-pug (node) - Node-RED
• node-red-contrib-velocity (node) - Node-RED
• There are likely more in the flows lib: Library - Node-RED

And if you want to use zod you can always import it in a function node. I did that in this demo here: Model Context Protocol (MCP) over HTTP - #4 by Steve-Mcl and you can import pretty much any lib see this article for details
