More documentation on building the backend adapters

[classicalguss]

I'm trying to build an adapter for yii1 which w eare using in our company. I'm finding it very difficult to find information on everything. Through hard work, I was able to finish most of it. However I am now stuck on ssr. I'm really struggling to come up with anything that can help me.
When I reach vite.config.js Inertiajs.com is telling me that I need to add ssr to laravel plugin. But of course since I'm writing my own adapter, I do not have laravel or this laravel plugin.

Please advise
