# bufferStuff   [![CodeFactor](https://www.codefactor.io/repository/github/tgpholly/bufferstuff/badge)](https://www.codefactor.io/repository/github/tgpholly/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:
```ts
// 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:
```ts
writer.writeByte(<number>);
```
You can find a list of all of the methods for [Writers](https://github.com/tgpholly/bufferStuff/blob/master/writers/IWriter.ts) and [Readers](https://github.com/tgpholly/bufferStuff/blob/master/readers/IReader.ts) in their interface files.
