Avoid Fastify's reply.raw and reply.hijack Despite Being A Powerful HTTP Streams Tool

This technical article discusses the advanced HTTP stream control features in the Fastify Node.js framework: reply.raw and reply.hijack(). It explains their use cases, such as implementing Server-Sent Events, but strongly advises developers to avoid them as a last resort due to the complexity, potential for breaking framework abstractions, and the responsibility required for low-level stream management.
