# `pipe-pipefy`

`pipe-pipefy` allows to combine functions, calling each function with the output of the last one.

## Usage

```javascript

import { pipe } from 'pipe-pipefy';

const getName = (person) => person.name;

const uppercase = (string) => string.toUpperCase();

const person = { name: 'Mathieu' };

const result =

  pipe(

    getName,

    uppercase

  )(person);

expect(result).toBe('MATHIEU');

```

```javascript

import { pipe, pipefy } from 'pipe-pipefy';

const getName = (person) => person.name;

const uppercase = (string) => string.toUpperCase();

const repeat = (string, n) => string.repeat(n);

const person = { name: 'Mathieu' };

const result =

  pipe(

    getName,

    uppercase,

    pipefy(repeat, 2)

  )(person);

expect(result).toBe('MATHIEUMATHIEU');

```

```javascript

import { pipe, pipefyIf } from 'pipe-pipefy';

const getName = (person) => person.name;

const uppercase = (string) => string.toUpperCase();

const repeat = (string, n) => string.repeat(n);

const person = { name: 'Mathieu' };

const someCondition = false;

const result =

  pipe(

    getName,

    uppercase,

    pipefyIf(someCondition, repeat, 2)

  )(person);

expect(result).toBe('MATHIEU');

```

```javascript

import { pipeAsync } from 'pipe-pipefy';

const getName = (person) => person.name;

const uppercase = (string) => string.toUpperCase();

const uppercaseAfterTimeout = (string) => {

  return new Promise(resolve => setTimeout(() => resolve(uppercase(string)), 50));

};

const person = { name: 'Mathieu' };

const result =

  await pipeAsync(

    getName,

    uppercaseAfterTimeout

  )(person);

expect(result).toBe('MATHIEU');

```
