isBuffer (Lodash Compatibility)

::: warning Use es-toolkit's isBuffer instead This isBuffer function operates slowly due to complex processing for Lodash compatibility.

Use the faster and more modern es-toolkit's isBuffer instead. :::

Checks if a value is a Buffer instance.

const result = isBuffer(value);

Usage

isBuffer(value)

Use isBuffer when you want to type-safely check if a value is a Buffer instance. It's useful when working with Buffer objects in Node.js environments. It also works as a type guard in TypeScript.

import { isBuffer } from 'es-toolkit/compat';

// Check Buffer instance
const buffer = Buffer.from('hello');
isBuffer(buffer); // true

// Other types return false
isBuffer('hello'); // false
isBuffer([1, 2, 3]); // false
isBuffer(new Uint8Array([1, 2, 3])); // false
isBuffer({}); // false
isBuffer(null); // false
isBuffer(undefined); // false

Parameters

• value (unknown): The value to check if it's a Buffer instance.

Returns

(boolean): Returns true if the value is a Buffer instance, false otherwise.
