# asynchandler

Callback adapter to use in a Promise. 

## Why

To adapt `callbacks paradigm` to `promises paradigm` in a nutshel.

## Installation

`$ npm i -s @allnulled/asynchandler`

## Usage

This example demonstrates how to use `asynchandler` with the node `fs` native module to read and write files using the asynchronous API:

```js

const asynchandler = require("@allnulled/asynchandler");

const example = async function() {

	await new Promise((ok, fail) => {

		fs.writeFile("file.txt", "Contents of the file", "utf8", asynchandler(ok, fail));

	});

	await new Promise(function(ok, fail) {

		fs.readFile("file.txt", "utf8", asynchandler(ok, fail));

	});

};

example();

```

## Source code

The source code of this module is very simple:

```js

module.exports = function(ok, fail) {

	return function(error, data) {

		if (error) {

			fail(error);

			return;

		}

		ok(data);

		return;

	}

};

```
