📚 Description

We were calling app:rendered hook just after ssr rendering is being done in Nuxt 3 <= 3.0.0-rc.6. #6042 changed this behavior in v3.0.0-rc.7 that app:rendered is being called with new rendered context to have access to constructed html but this means, it is too late to modify payload.

This PR reverts app:rendered back to previous behavior with new limited { ssrContext } context only. (breaking change)

Nitro plugins have access to the final rendered context via render:html (breaking change: nuxt:app:rendered renamed for nitro plugins to be simpler, consistent with render:response hook and not confused with app:rendered lifecycle hook)

Example usage: (nitro plugin)

// server/plugins/render.tsexportdefaultdefineNitroPlugin((nitroApp)=>{nitroApp.hooks.hook('render:html',(html,{ event })=>{console.log({ html })})nitroApp.hooks.hook('render:response',(response,{ event })=>{console.log(response)})})
