Buffer
The Buffer API in Node.js is one of the most commonly used Node.js APIs for manipulating binary data. Every Buffer instance extends from the standard
Uint8Array class, but adds a range of unique capabilities such as built-in base64 and hex encoding/decoding, byte-order manipulation, and encoding-aware substring searching.
A Buffer extends from Uint8Array. Therefore, it can be used in any Workers API that currently accepts Uint8Array, such as creating a new Response:
You can also use the Buffer API when interacting with streams:
