How can I validate and serialize object myslef in the same way Fastify does when handling route?

[vatosarmat]

Hello. My application also sends some data by websocket and I would like it to be validated and serialized in the same way with the same schema I set it up in my route. What is the easiest and most idiomatic way? Thanks.

Just to understand better, you want to validate the incoming ws payloads after the upgrade has been done?

I don't interact with ws upgrades and other low-level details, I'm just sending data to socket.io socket and would like to reuse validation logic from normal HTTP REST routes for that data.
It seems that I have to create my own Ajv instance and compile schemas by myself, but I thought that maybe it is possible to extract them from FastifyInstance?
Just found that FastifyInstance has validatorCompiler and serializerCompiler and seems like I should compile my schemas with them, but they both undefined
