Customize Renderer/SSR implementation

[davidmyersdev]

Hello 👋

I'm looking for a way to customize the InertiaRails::Renderer class. Some things I'd like to do are:

• Instrument individual code paths with OpenTelemetry (e.g. the HTTP call for SSR)
• Implement custom error handling/messaging for SSR errors (currently suppressed by Inertia with an implicit fallback to CSR)
• Cache SSR responses (similar to is it possible to cache ssr response inside an action? #251)
• Automatically transform props to camel-case (similar to Auto-serialization of ActiveRecord models #68 (comment))

Currently, I work around this by performing the SSR network call manually and rendering that HTML to the same layout that Inertia would render. This isn't ideal, as I have to recreate some of the functionality that Inertia already handles well (the InertiaRails::Renderer class).

I'd be happy to put a PR together if this sounds like something you'd allow.

Hey @davidmyersdev!

Yup, this is something I have in my todo for a long time! What interface for customization are you thinking about?

FYI there's now a prop transformation option available via Inertia config:
