# binconv
[](https://www.npmjs.com/package/binconv) [](https://circleci.com/gh/nwtgck/binconv-npm)
Binary converters for Blob, Uint8Array, ReadableStream, ArrayBuffer, string in JavaScript/TypeScript
## Installation
```bash
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
```ts
function mergeUint8Array(a: Uint8Array, b: Uint8Array): Uint8Array;
function mergeAllUint8Arrays(arrays: ReadonlyArray): Uint8Array;
```
## Usage
```ts
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.
```ts
import {blobToReadableStream} from 'binconv/dist/src/blobToReadableStream';
const blob = new Blob(["this is a blob"]);
const readableStream = blobToReadableStream(blob);
```
