Hooks vs. Decorators

[wscherphof]

💬 Question here

I can decorate requests using fastify.decorateRequest.
I can also create an onRequest hook and extend the request object there.

What are the fundamental differences between the two approaches?

Your Environment

• node version: 16
• fastify version: 3
• os: Linux

• fastify.decorateRequest allows you to add a property to the request object
• The onRequest is a hook that is triggered in every request (based on the scope)

Those features are completely different.

Does the introduction to decorators clear things up? https://www.fastify.io/docs/latest/Reference/Decorators/
