[Typo]: Client Components running on the server

Summary

The "use client" docs state:

During render, the framework will server-render the root component and continue through the render tree, opting-out of evaluating any code imported from client-marked code.

The server-rendered portion of the render tree is then sent to the client. The client, with its client code downloaded, then completes rendering the rest of the tree.

This implies that Client Components are skipped during SSR, but I don’t think that’s true.

Details

My understanding is that Client Components will render on the server during SSR, and hydrate on the client. This is necessary so that the server-generated HTML is complete; if Client Components were truly skipped during SSR, our HTML would be full of holes that would only be filled in after hydration.

Another way to verify this is to add a console.log() to a Client Component, within a component function. The log will be printed in our server terminal, showing that the code is indeed evaluated on the server.

It’s possible I'm misunderstanding what is meant by "render" in this context, but it really makes it sound like the server skips any files that are marked with "use client". And unless this changed very recently, it is demonstrably untrue.

Leggi la pagina di riferimento di “use client” e i passaggi citati sul rendering lato server e sull’albero di rendering. Verifica il comportamento descritto utilizzando il contesto della documentazione collegata e l’output della console lato server riportato. Il lavoro è completato quando la formulazione viene rivista in modo da spiegare accuratamente i Client Components durante l’SSR, senza suggerire che il codice contrassegnato come client venga completamente ignorato.
