## Installation

```console
npm i iobuffer
```

## API

Complete [API documentation](http://image-js.github.io/iobuffer/)

## Usage example

```js
const { IOBuffer } = require('iobuffer');

const io = new IOBuffer();
// Pointer offset is 0
io.writeChars('Hello world') // Write 11 chars, pointer offset now 11
  .writeUint32(42) // Write 32-bit int (default is little-endian), pointer offset now 15
  .setBigEndian() // Switch to big-endian mode
  .writeUint32(24) // Write another 32-bit int, but big-endian, pointer offset now 19
  .mark() // Bookmark current pointer offset (19)
  .skip(2) // Pointer offset now 21
  .writeBoolean(true) // Write 0xff, pointer offset now 22
  .reset() // Go to bookmarked pointer offset, pointer offset now 19
  .setLittleEndian() // Go back to little endian mode
  .writeUint16(18) // Write 16-bit unsigned integer in the previously skipped 2 bytes, pointer offset now 21
  .rewind() // Pointer offset back to 0
  .toArray(); // Get a Uint8Array over the written part [0-21] of the internal ArrayBuffer
```
