HTML Streaming

In general, we recommend using pageContext.httpResponse.pipe() for integrating HTML streaming to your server, see HTML Streaming > Basics.

But Fastify doesn't seem to expose any writable stream (as far as we know). As a workaround, you can directly use Node.js's writable stream as shown here. If this workaround doesn't work out for you, you can fallback to pageContext.httpResponse.getReadableNodeStream().
