has-binary

What is has-binary?

The has-binary npm package is a utility that checks if a given JavaScript object or array contains any binary data. This can be useful in various scenarios, such as when you need to determine if an object contains binary data before performing certain operations like serialization or transmission over a network.

What are has-binary's main functionalities?

Check if an object contains binary data

This feature allows you to check if a given object contains any binary data. In this example, the object contains a Buffer, which is binary data, so the function returns true.

const hasBinary = require('has-binary');
const obj = { key: 'value', buffer: Buffer.from('binary data') };
console.log(hasBinary(obj)); // true

Check if an array contains binary data

This feature allows you to check if a given array contains any binary data. In this example, the array contains a Uint8Array, which is binary data, so the function returns true.

const hasBinary = require('has-binary');
const arr = ['string', new Uint8Array([1, 2, 3])];
console.log(hasBinary(arr)); // true

Other packages similar to has-binary

is-buffer

The is-buffer package is a simple utility to check if a given object is a Buffer. While it is more limited in scope compared to has-binary, it can be useful if you only need to check for Buffer objects specifically.

bufferutil

The bufferutil package provides utilities for working with Buffer objects, including checking if an object is a Buffer. It offers more functionality for Buffer manipulation but does not provide the broader binary data detection capabilities of has-binary.

typedarray-to-buffer

The typedarray-to-buffer package converts TypedArray instances to Buffer objects. While it does not directly check for binary data, it can be used in conjunction with other utilities to handle binary data more effectively.
