hapijs/vise

@hapi/vise is a lightweight utility that lets you treat a collection of Buffers or strings as a single contiguous data source, providing seamless read, slice, and length operations across the combined content. It’s primarily aimed at developers building HTTP servers with the hapi framework—especially for handling streamed payloads and response bodies—but can be used in any Node.js project that needs efficient, buffer‑agnostic concatenation.
