# BlobReader

Simple interface for reading blobs, sequentially. 3202 bytes minified and 1172 bytes minified + gzipped.

# Example

```javascript

// Blob definition

var uint8 = new Uint8Array([1, 2]);

var uint16 = new Uint16Array([3]);

var uint82 = new Uint8Array([4, 3]);

var uint32 = new Uint32Array([8]);

var blob = new Blob([uint8, uint16, uint82, uint32]);

// Reading the blob

BlobReader(blob)

.readUint8('uint8', 2)

.readUint16('uint16')

.readUint8('uint82', 2)

.skip()

.readUint32('uint32')

.commit(function (data) {

  expect(data.uint8[0]).toBe(1);

  expect(data.uint8[1]).toBe(2);

  expect(data.uint16).toBe(3);

  expect(typeof data.uint82).toBe('number');

  expect(data.uint82).toBe(4);

  expect(data.uint32).toBe(8);

});

```

# Roadmap

* Add support for synchronous blob reading in workers.

* *Add support for observables/promises.*
