stream-with-known-length-to-buffer

Convert a Readable Stream with a known length into a Buffer

This package converts a Readable Stream into a Buffer, with just one Buffer allocation (excluding allocations done internally by the streams implementation).

This is lighter-weight choice than stream-to-array when the total stream length is known in advance. This whole package is 15 lines.

This module is used by WebTorrent.

  console.log(buf)
