> Google Recapctha v2 solver with puppeteer. You can simply use it in your project by passing to the constructor your Page object.
> The solver is using SpeechToText recognition, you can use one of our integrated solvers with your API key or to provide your own solving function.
> You can also integrate your own logger.

Prerequisites

This project requires NodeJS (version 8 or later) and NPM.
Node and NPM are really easy to install.

Getting Started

These instructions will help to you install the package in your project, set it and use it.
See Contributing for notes on how to help and contribute this project.

Installation

BEFORE YOU INSTALL: please read the prerequisites

To install and set up the library, run:

``sh
$ npm install puppeteer-recaptcha-solver
`

Usage

To use, simply create the object and execute the solve command.

Example:

`ts
(async () => {
const browser = await puppeteer.launch({
headless: false,
});
const page = await browser.newPage();

const solver = new ReCaptchaSolver({
page,
maxRetries: 3,
transcriber: Transcribers.witAI,
apiKey: 'YOUR_API_KEY'
});

await page.goto(
'https://recaptcha-demo.appspot.com/recaptcha-v2-checkbox.php'
);

const solved = await solver.solve();

console.log('Captcha solved: ', solved);
await page.screenshot({ path: 'example/example.png' });
await browser.close();
})();
`

API

$3

`ts
const solver = new ReCaptchaSolver({
page,
log,
maxRetries: 3,
transcriber: Transcribers.witAI,
apiKey: 'YOUR_API_KEY'
});
`

A constructor to the object.

#### Fields

Supported options for the constructor field are listed below.

| Field | Type | Default value | Required | Description |
| --- |-------------| --- | --- |-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|
| page | Page | | Yes | puppeteer page object |
| log | Logger | console.log | No | A logger that the solver will use. You can also use the default logger or noopLogger to disable the logs |
| transcriber | Transcriber | witAI | No | A transcriber that the solver will use to transcriber the audio to text. You can can choose between witAI or googleSpeechToText by passing Transcribers.witAI or Transcribers.googeSpeechToText or passing you own Transcriber function. |
| maxRetries | number | 3 | No | Total number of retries until the captcha is solved |
| apiKey | string | | No | API key to your transcribe service |

$3

`ts
const solved: boolean = await solver.solve();
`

A command that will start the solving process.
Returns a Promise to indicate if the captcha successfully solved.
