# bufferStuff [](https://www.codefactor.io/repository/github/tgpholly/bufferstuff) [](https://github.com/tgpholly/bufferStuff/actions/workflows/node.js.yml) [](https://www.npmjs.com/package/bufferstuff)

|
A set of utility classes for reading and writing binary data in NodeJS.
|
|
|
|
## 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://git.eusv.net/tgpholly/bufferStuff/src/branch/master/writers/IWriter.ts) and [Readers](https://git.eusv.net/tgpholly/bufferStuff/src/branch/master/readers/IReader.ts) in their interface files.
