To Array Buffer: Convert Buffer, Data URLs, Files, Response, Text, and Typed Arrays to Array Buffers

# install

```bash

npm install toab

```

# usage

# convert file buffer to array buffer

```javascript

const fs = require("fs");

const toab = require("toab");

const buffer = fs.readFileSync("test.png");

const arrayBuffer = await toab(buffer);

```

# convert File to an array buffer

```javascript

document.querySelector('input').addEventListener('change', async event => {

    const file = event.target.files[0];

    const arrayBuffer = await toab(file);

});

```

# convert data url to array buffer

```javascript

// the context comes from a canvas element 

const url = context.toDataURL('image/jpeg');

// url is data:image/jpeg;base64,/9j/4AAQSkZJRgABA"

const arrayBuffer = await toab(url);

```

# convert data view to array buffer

```javascript

const arrayBuffer = await toab(dataView)

```

# convert typed arrays to array buffers

```javascript

const arrayBuffer = await toab(int8Array)

const arrayBuffer = await toab(uint8Array)

const arrayBuffer = await toab(int16Array)

const arrayBuffer = await toab(uint16Array)

const arrayBuffer = await toab(int32Array)

const arrayBuffer = await toab(uint32Array)

const arrayBuffer = await toab(float32Array)

const arrayBuffer = await toab(float64Array)

const arrayBuffer = await toab(bigInt64Array)

const arrayBuffer = await toab(bigUint64Array)

```

# convert text to an array buffer (in UTF-8)

```javascript

const arrayBuffer = await toab("Hello, I'm a String.");

```

# convert fetch Response to an array buffer

```javascript

const response = await fetch("https://example.org/file.dat");

const arrayBuffer = await toab(response);

// or for a one-line solution

const arrayBuffer = await fetch("https://example.org/file.dat").then(toab);

```
