bufferStuff 
A set of utility classes for reading and writing binary data in NodeJS and the browser.
Motivations
I tend to write code a lot that needs to read and write from buffers and this is sometimes in big-endian too, so I decided eventually to make a utility to help me with that which is what you see here. Originally I had two variants of bufferStuff that were for LE and BE respectively but this got difficult to manage so I rewrote it in TypeScript and added support for both reader / writer types.
Usage
You can create an instance of the Reader and Writer classes like this:
// You *must* be expicit with the endianness
const leReader:IReader = createReader(Endian.LE, buffer);
const beReader:IReader = createReader(Endian.BE, buffer);
// Size is optional, will dynamically allocate if left empty or 0
const leWriter:IWriter = createWriter(Endian.LE, <optional: size>);
const beWriter:IWriter = createWriter(Endian.BE, <optional: size>);
I tried to keep it as simple as possible to use, for example if you want to write a (signed) byte you do as follows:
writer.writeByte(<number>);
You can find a list of all of the methods for Writers and Readers in their interface files.
