# rewrite-async [![Build Status](https://travis-ci.org/lukeed/rewrite-async.svg?branch=master)](https://travis-ci.org/lukeed/rewrite-async)

> Rewrite async functions as generators; via RegExp

Unlike [`async-to-gen`](https://www.npmjs.com/package/async-to-gen), this does not register a runtime. Instead, the "transpiling" occurs only as needed.

Also, this is _only_ executes a **string conversion**! You will have to look to other modules in order to execute the returned string.

> **Note:** Although `eval()` will work, it's generally (and strongly) not recommended.

Built with [`Bluebird.coroutine`](http://bluebirdjs.com/docs/api/promise.coroutine.html) in mind. :wink:

## Install

```
$ npm install --save rewrite-async
```


## Usage

```js
const rewriteAsync = require('rewrite-async');

rewriteAsync('async function (one, two) {}');
//=> 'function* (one, two) {}'

rewriteAsync('var foo = async (req, res) => {}');
//=> 'var foo = function* (one, two) {}'

rewriteAsync('async one => await foo(one)');
//=> 'function* (one) {return yield foo(one)}'
```


## API

### rewriteAsync(input)

#### input

Type: `string`

A function's contents (via `.toString()`) or any `utf-8` string that contains function definitions.

An input argument to this GitHub Action is being exported as an environment variable. If a user of this action passes untrusted input, it could be used in an insecure manner by subsequent workflow steps.

What are GitHub Actions taint flows?

GitHub Actions: Input argument exported as environment variable

An input argument to this GitHub Action is being passed back as an output. If a user of this action passes untrusted input, it could be used in an insecure manner by consuming workflows.

GitHub Actions: Input argument passed back as output

An input argument to this GitHub Action flows into a dangerous sink (such as shell command execution). This could allow a malicious user to inject commands or exploit the action.
