About
Convert an ArrayBuffer to a Buffer
The Node.js Buffer API predates the introduction of ArrayBuffer into the JavaScript language. Bun implements both.
Use the static Buffer.from() method to create a Buffer from an ArrayBuffer.
```ts theme={"theme":{"light":"github-light","dark":"dracula"}} const arrBuffer = new ArrayBuffer(64); const nodeBuffer = Buffer.from(arrBuffer);
***
To create a `Buffer` that only views a portion of the underlying buffer, pass the offset and length to the constructor.
```ts theme={"theme":{"light":"github-light","dark":"dracula"}}
const arrBuffer = new ArrayBuffer(64);
const nodeBuffer = Buffer.from(arrBuffer, 0, 16); // view first 16 bytesSee [Docs > API > Binary Data](/runtime/binary-data#conversion) for complete documentation on manipulating binary data with Bun.
