Thank you for a great streams overview!

How would you write out the correct version of HTTP stream example with stream/promises pipeline, pass res as last parameter? And for fastify, reply.send?

use `@fastify/static` :). Don't stream files directly because there are infinite edge cases that will inevitably result in a security issues in your server.

[Matteo Collina](https://hashnode.com/@matteocollina) Thanks for the reply! Yes, understood for static files which can be directly served, but I was thinking more of the case when there is a pipeline - reading file then transforming and finally sending as a response...

[Stasa Stanisic](https://hashnode.com/@stasas) you can just call `reply.send(stream)` or `return stream` in your Fastify route. Using barebone HTTP, you should do `pipeline(a, b, c, res, (err) => { ... })`.
