binconv

Binary converters for Blob, Uint8Array, ReadableStream, ArrayBuffer, string in JavaScript/TypeScript

Installation

npm i -S binconv

Converters

Here are avaiable converters.
Naming rule: A → B should be aToB().

conversion	function
Base64 → Uint8Array	base64ToUint8Array()
Blob → ArrayBuffer	blobToArrayBuffer()
Blob → ReadableStream	blobToReadableStream()
Blob → Uint8Array	blobToUint8Array()
ReadableStream → Blob	readableStreamToBlob()
ReadableStream → Uint8Array	readableStreamToUint8Array()
string → Uint8Array	stringToUint8Array()
string → ArrayBuffer	stringArrayBuffer()
Uint8Array → ArrayBuffer	uint8ArrayToArrayBuffer()
Uint8Array → Base64	uint8ArrayToBase64()
Uint8Array → Blob	uint8ArrayToBlob()
Uint8Array → hex string	uint8ArrayToHexString()
Uint8Array → ReadableStream	uint8ArrayToReadableStream()
Uint8Array → string	uint8ArrayToString()

Other binary utilities

function mergeUint8Array(a: Uint8Array, b: Uint8Array): Uint8Array;
function mergeAllUint8Arrays(arrays: ReadonlyArray<Uint8Array>): Uint8Array;

Usage

import * as binconv from 'binconv';

const blob = new Blob(["this is a blob"]);
const readableStream = binconv.blobToReadableStream(blob);

Usage (on-demand import)

You can import only specific conversion to reduce file size.

import {blobToReadableStream} from 'binconv/dist/src/blobToReadableStream';

const blob = new Blob(["this is a blob"]);
const readableStream = blobToReadableStream(blob);
