# pipeline

A modular pipeline architecture

## [Module](lib/Module.js)

A superclass for all modules. Inherents `EventEmitter`.

### [SourceModule](lib/SourceModule.js)

A superclass for modules that emit output and receive no inputs.

``` javascript

const Greeter = SourceModule.create(async function(name) {

	setInterval(() => {

		this.emit('output', `Hello, ${name}!`);

	}, 1000);

});

const greeter = new Greeter('Monty');

// Hello, Monty!

```

### [TransformModule](lib/TransformModule.js)

A superclass for all modules that transform an input to produce a single output.

``` javascript

const LessThan = TransformModule.create(async (x, y) => x < y);

const lessThan = new LessThan(10);

// 9 => true

// 11 => false

```

## [Pipeline](lib/Pipeline.js)

``` javascript

const Generator = SourceModule.create(async function(max) {

	setInterval(() => {

		this.emit('output', Math.floor(Math.random() * max))

	}, 100);

});

const Multiplier = TransformModule.create(async (number, multiplier) => {

	return number * multiplier;

});

const Logger = TransformModule.create(async number => {

	console.log(number);

});

new Pipeline([

	new Generator(100),

	new Multiplier(0.5),

	new Logger()

]);

```
