## About
While I'm not overjoyed about how performant the internals will operate, I wanted a readable stream that was ACTUALLY A READABLE STREAM. Not a streams1 stream masquerading as streams2. As soon as somebody writes a better concat stream as a readable stream with a nice simple API, this baby is going to develop some serious abandonment issues.

## Installation
```bash
npm install sandwich-stream --save
```

**note**: this code was made using it [TypeScript](https://www.typescriptlang.org/), and its typings are linked in [package.json](./package.json), so there's no need of installing _@types/sandwich-stream_ or anything related. 

## Usage
```typescript
import { SandwichStream } from 'sandwich-stream';
// OR EVEN:
// const SandwichStream = require('sandwich-stream');

const sandwich = SandwichStream({
    head: 'Thing at the top\n',
    tail: '\nThing at the bottom',
    separator: '\n ---- \n'
});

sandwich.add(aStreamIPreparedEarlier)
        .add(anotherStreamIPreparedEarlier)
        .add(aFurtherStreamIPreparedEarlier)
        .pipe(process.stdout);

// The thing at the top
//  ---- 
// Stream1
//  ---- 
// Stream2
//  ---- 
// Stream3
// The thing at the bottom
```
## Configuration Options
* `head` option takes a string/buffer and pushes the string before all other content
* `foot` option takes a string/buffer and pushes the string after all other data has been pushed
* `separator` option pushes a string/buffer between each stream
* [Readable Options](https://github.com/DefinitelyTyped/DefinitelyTyped/blob/be662c475da091788139b486a55708f02e2880b6/types/node/index.d.ts#L6485) can also be passed through.

## API
Too add a stream use the **.add** method: `sandwich.add(streamVariable);`
