# BRW - Binary Reader Writer

## Install

`npm install brw`

## Reader

```js

var Reader = require("brw").Reader;

var r = new Reader(arrayBuffer);

// Static length read functions

r.readInt8()

r.readInt16()

r.readInt32()

r.readUInt8()

r.readUInt16()

r.readUInt32()

r.readFloat32()

r.readFloat64()

// Variable length integer

r.readVarInt()

r.readUVarInt()

// UTF8 String read

r.readString() // Assumes the string has a length prefix

r.readString({ prefixed: false, len: 100 }) // Read 100 characters

```

## Writer

```js

var Writer = require("brw").Writer;

var w = new Writer();

// Static length read functions

w.writeInt8(var)

w.writeInt16(var)

w.writeInt32(var)

w.writeUInt8(var)

w.writeUInt16(var)

w.writeUInt32(var)

w.writeFloat32(var)

w.writeFloat64(var)

// Variable length integer

w.writeVarInt(var)

w.writeUVarInt(var)

// UTF8 String read

w.writeString(var) // Prefixed string with length

w.writeString(var, { prefixed: false })

```
