buffer.Buffer.readInt16BE

offset?: number

): number;

Reads a signed, big-endian 16-bit integer from buf at the specified offset.

Integers read from a Buffer are interpreted as two's complement signed values.

import { Buffer } from 'node:buffer';

const buf = Buffer.from([0, 5]);

console.log(buf.readInt16BE(0));
// Prints: 5

@param offset

Number of bytes to skip before starting to read. Must satisfy 0 <= offset <= buf.length - 2.
