In this article we will describe how to use the 2captcha-solver extension together with Puppeteer. Puppeteer is a Node library that allows you to launch a browser and perform various actions in it, usage examples are described here. Puppeteer Node.js library is a great tool for a variety of tasks that require browser automation. Advantage of Puppeteer is its simplicity and the ability to work in headless mode. There are plugins for Puppeteer that allow you to hide the fact of automation. Hiding the fact of automation is important when development parsers, as this will allow the browser to look more like a person and not be exposed.

In this article we will use Puppeteer, puppeteer-extra and puppeteer-extra-plugin-stealth. puppeteer-extra is a lightweight wrapper around Puppeteer, and puppeteer-extra-plugin-stealth is an addition to puppeteer-extra designed to hide traces of automation.

In the step-by-step description below, we will describe how to solve the captcha on the page https://2captcha.com/demo/recaptcha-v2.

1. Installing components
Installing Puppeteer and other required packages:
npm i puppeteer puppeteer-extra puppeteer-extra-plugin-stealth

2. Setting up the extension
Download archive with the extension, and unzip it to the folder ./2captcha-solver in the root of the project.

The extension has many settings, including automatic solution of the specified type of captcha, support for proxy, and other settings. The settings are available in the file ./common/config.js. To add settings for the automatic reCAPTCHA V2 solution, you need to open the file ./common/config.js and change the value of the autoSolveRecaptchaV2 field to true.

Next, you need to configure the extension:

  1. Enter your API key in the extension settings file ./common/config.js. Your key must be written to the value of the apiKey field. You can see and copy you're API key on the page.
    Example: apiKey: "8080629c1221fdd82m8080000ff0c99c"
  2. Disable opening the extension settings page after installation. To do this, in the file ./manifest.json delete the following lines:
Code: 
"options_ui": {

    "page": "options/options.html",

    "open_in_tab": true

},


3. Browser Automation
Launching and initializing the extension in Puppeteer:

Code: 
const puppeteer = require('puppeteer-extra');
const StealthPlugin = require('puppeteer-extra-plugin-stealth');
const { executablePath } = require('puppeteer');

(async () => {
  const pathToExtension = require('path').join(__dirname, '2captcha-solver');
  puppeteer.use(StealthPlugin())
  const browser = await puppeteer.launch({
    headless: false,
    args: [
      `--disable-extensions-except=${pathToExtension}`,
      `--load-extension=${pathToExtension}`,
    ],
    executablePath: executablePath()
  });

  const [page] = await browser.pages()
})();

4. Performing actions
After solving the captcha, we can start doing the necessary actions on the page. In our example, we will click on the "Check" button to check the correctness of the received captcha solution. After successfully passing the check, you will see the message "Captcha is passed successfully!".

Code: 
// Click on the "Check" button to check the successful solution of the captcha.
await page.click("button[type='submit']")

Congratulations, the captcha has been successfully passed! The full source code of the example is here.

Useful information:
  • The extension has many settings, for example, automatic solution of the specified type of captcha or support for proxy, all these settings are available in the file ./common/config.js, in the folder with the unpacked extension. To automatically send reCAPTCHA V2, in the file ./common/config.js change the value of the autoSolveRecaptchaV2 field to true.
  • You can use sandbox mode, for testing. In sandbox mode, sent captchas will be sent to you. Learn more about sandbox you can read here.
  • Puppeteer running in headless mode does not support loading extension, to solve this problem you can use xvfb.
