json-schema validation

[jacques_clement]

Hi,

Has anyone ever worked on implementing one of the many JSON Schema validation modules/libraries that exist out there? It takes a little bit of work to adjust them to a script include (unless there is an easy solution to convert an AMD or CommonJS library into something usable in ServiceNow (have not found so far).

With scripted REST API ramping up, it would be very interesting for ServiceNow to add something like this out of the box anyhow.

Any thoughts?

Regards,

Hi Jacques,

I couldn't agree more than it would be great to have some validation built in - especially for incoming REST payloads. Outbound is pretty safe when you construct your object and use JSON.stringify(), but incoming would be very nice to validate before parsing it.

I invite you to open an enhancement request! Our product managers DO listen.

Thanks for taking the time, will do.

So we finally managed to implement JSON schema validation by adapting the tv4 library to a script include. Now building a scripted API has become so much easier when it comes to verifying the incoming payload. Hope this will help others.

Hi Jacques.

Did you do much modification to the tv4.js library or was basically a drop in as a script include?

I tested adding the library without modification as a script include on my private instance at it seems to work fine but I'm wondering if using it unmodified could have some other consequences like in system performance.

Best regards,
