assistant: To convert your Puppeteer script into an Express router using CommonJS (CJS) modules, you should structure it to handle requests. This involves setting up an Express app, defining a route, and using the Puppeteer logic within that route. Below is how you can implement this:

1. Install Express if you haven't already: `npm install express`.
2. Use the Express framework to handle HTTP requests and route logic.

Here's the converted code:

```javascript
const express = require('express');
const { connect } = require('puppeteer-real-browser');

const router = express.Router();

router.get('/screenshot', async (req, res) => {
  try {
    const { page } = await connect({
      headless: 'auto',
      fingerprint: true,
      turnstile: true,
      tf: true,
    });

    await page.goto('https://www.g2.com/products/asana/reviews', {
      waitUntil: "networkidle2"
    });
    
    await page.waitForTimeout(15000);
    const screenshotPath = 'puppeteer-real-browser.png';
    await page.screenshot({ path: screenshotPath });
    await page.close();

    res.status(200).send(`Screenshot saved at ${screenshotPath}`);
  } catch (error) {
    console.error(error);
    res.status(500).send('An error occurred while taking the screenshot.');
  }
});

module.exports = router;
```

Then, in your main server file (e.g., `app.js`), you would include this router:

```javascript
const express = require('express');
const screenshotRouter = require('./path-to-your-router-file');

const app = express();
const PORT = process.env.PORT || 3000;

app.use('/api', screenshotRouter);

app.listen(PORT, () => {
  console.log(`Server is running on port ${PORT}`);
});
```

With this setup, visiting `http://localhost:3000/api/screenshot` in your browser will trigger the Puppeteer script and save a screenshot. Make sure `puppeteer-real-browser.png` path is accessible based on your development environment and permissions.
user: MAKE IT NOT SCREENSHOT ANYTHING, just return the page title
assistant: To modify your Express router to return the page title instead of taking a screenshot, you can adjust the Puppeteer logic to extract the page title and send it back as the response. Here’s how you can achieve that:

1. Install Express if you haven’t already: `npm install express`.
2. Adjust the route logic to fetch and return the page title.

Below is the modified Express router code:

```javascript
const express = require('express');
const { connect } = require('puppeteer-real-browser');

const router = express.Router();

router.get('/page-title', async (req, res) => {
  try {
    const { page } = await connect({
      headless: 'auto',
      fingerprint: true,
      turnstile: true,
      tf: true,
    });

    await page.goto('https://www.g2.com/products/asana/reviews', {
      waitUntil: "networkidle2"
    });
    
    await page.waitForTimeout(15000);
    const pageTitle = await page.title();  // Get the page title
    await page.close();

    res.status(200).send(`Page title: ${pageTitle}`);
  } catch (error) {
    console.error(error);
    res.status(500).send('An error occurred while fetching the page title.');
  }
});

module.exports = router;
```

Then, in your main server file (e.g., `app.js`), you would include this router:

```javascript
const express = require('express');
const pageTitleRouter = require('./path-to-your-router-file');

const app = express();
const PORT = process.env.PORT || 3000;

app.use('/api', pageTitleRouter);

app.listen(PORT, () => {
  console.log(`Server is running on port ${PORT}`);
});
```

With this setup, visiting `http://localhost:3000/api/page-title` in your browser will trigger the Puppeteer script, and it will respond with the title of the specified page.

1|kairo    |   code: 'ERR_LAUNCHER_PATH_NOT_SET'
1|kairo    | }
assistant: The error message you're seeing indicates that Puppeteer is unable to find a valid Chrome/Chromium installation on your VPS. Here are a few steps you can take to resolve this issue:

### Option 1: Install Chrome/Chromium on Your VPS
1. **Install Chromium or Google Chrome:**
    - On Debian/Ubuntu systems, you can install Chromium using the following commands:
      ```bash
      sudo apt update
      sudo apt install chromium-browser
      ```

    - Alternatively, download and install Google Chrome directly:
      ```bash
      wget https://dl.google.com/linux/direct/google-chrome-stable_current_amd64.deb
      sudo apt install ./google-chrome-stable_current_amd64.deb
      ```

2. **Set the `CHROME_PATH` Environment Variable:**
    - Find the path to the Chrome/Chromium executable. It could be something like `/usr/bin/google-chrome` or `/usr/bin/chromium-browser`.
    - Set the `CHROME_PATH` environment variable:
      ```bash
      export CHROME_PATH=/path/to/chrome
      ```
    - Alternatively, you can set this variable directly in your Node.js script before calling `connect`.

### Option 2: Use Puppeteer's Built-in Chromium
If you prefer not to install Chromium manually, you can opt for Puppeteer to use its bundled version:
1. **Switch to Puppeteer instead of Puppeteer-Core:**
   - If you're using `puppeteer-core` or another library like `puppeteer-real-browser`, switch to using `puppeteer`, which downloads a compatible Chromium version:
     ```bash
     npm uninstall puppeteer-real-browser
     npm install puppeteer
     ```

2. **Update Your Code to Use Puppeteer:**
   - Change the import and the connection method to use Puppeteer. Here's an example:

     ```javascript
     const express = require('express');
     const puppeteer = require('puppeteer');

     const router = express.Router();

     router.get('/page-title', async (req, res) => {
       try {
         const browser = await puppeteer.launch();
         const page = await browser.newPage();
        
         await page.goto('https://www.g2.com/products/asana/reviews', {
           waitUntil: "networkidle2"
         });
        
         const pageTitle = await page.title();
         await browser.close();

         res.status(200).send(`Page title: ${pageTitle}`);
       } catch (error) {
         console.error(error);
         res.status(500).send('An error occurred while fetching the page title.');
       }
     });

     module.exports = router;
     ```

### Additional Notes

- **Permissions:** Ensure that your user has the necessary permissions to install software and set environment variables on your VPS.
- **Headless Mode:** When running on a server without a GUI, make sure to run Puppeteer in headless mode (as shown in the code above with `await puppeteer.launch({ headless: true })`).

This should help you resolve the issue by ensuring that a Chromium browser is available for Puppeteer to use.
user: add all possible args to make this as efficient and fast as possible
assistant: To make Puppeteer as efficient and fast as possible, you can configure several options when launching the browser, as well as when navigating to a page. Here's how you might do that:

### Key Options for Efficiency:

1. **Headless Mode**: Ensure the browser runs in headless mode, which is faster because it doesn't render a UI.
2. **Disable Unnecessary Features**: Disable things like GPU hardware acceleration and images to save resources.
3. **Set a Specific User Agent**: This can sometimes help speed up page loads.
4. **Adjust Timeout Settings**: Customize timeouts to minimize unnecessary waits.
5. **Reduce Script Processing and Rendering**: Disable features that are not needed for your task.

Here’s how you can apply these optimizations:

```javascript
const express = require('express');
const puppeteer = require('puppeteer');

const router = express.Router();

router.get('/page-title', async (req, res) => {
  try {
    const browser = await puppeteer.launch({
      headless: true,
      args: [
        '--no-sandbox',  // Disables the sandbox for performance.
        '--disable-setuid-sandbox',  // For environments where setuid sandbox is not allowed.
        '--disable-gpu',  // Disables GPU hardware acceleration.
        '--disable-dev-shm-usage',  // Uses /tmp dir instead of /dev/shm (more space).
        '--no-zygote',  // Helps to prevent resource restrictions on some Linux distributions.
        '--single-process',  // Runs everything in a single process for memory optimization.
        '--disable-gl-extensions', // Disables unnecessary graphic extensions.
        '--disable-accelerated-video-decode',  // Reduces load related to video processing.
      ],
      ignoreHTTPSErrors: true,  // Ignores HTTPS errors to proceed with navigation.
    });

    const page = await browser.newPage();

    // Optimize page settings for faster loads.
    await page.setUserAgent('Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/58.0.3029.110 Safari/537.3');
    await page.setJavaScriptEnabled(true);  // Ensure JavaScript is enabled as needed.
    await page.setRequestInterception(true);

    // Intercept requests to disable images and other resource types that are not needed.
    page.on('request', (request) => {
      const resourceType = request.resourceType();
      if (['image', 'stylesheet', 'font'].includes(resourceType)) {
        request.abort();
      } else {
        request.continue();
      }
    });

    await page.goto('https://www.g2.com/products/asana/reviews', {
      waitUntil: 'domcontentloaded',  // Ensures HTML is loaded without waiting for full resources.
      timeout: 30000,  // Set timeout to 30 seconds to avoid prolonged waits.
    });

    const pageTitle = await page.title();  // Get the page title
    await browser.close();

    res.status(200).send(`Page title: ${pageTitle}`);
  } catch (error) {
    console.error(error);
    res.status(500).send('An error occurred while fetching the page title.');
  }
});

module.exports = router;
```

### Additional Considerations:
- **Resource Management**: Manage caching and cookies if frequent visits to similar pages are needed.
- **Environment**: Make sure the environment (like a VPS) has sufficient CPU and memory.
- **Concurrency**: If processing multiple pages, limit concurrency to avoid CPU overload.

These optimizations should help improve the speed and efficiency of your Puppeteer script by focusing on the tasks critical to your needs while avoiding unnecessary processing.
user: use puppeteer stealth
assistant: To enhance Puppeteer's ability to avoid detection as an automated tool, you can utilize the `puppeteer-extra` package along with its `puppeteer-extra-plugin-stealth` plugin. This setup helps disguise Puppeteer's activities by applying various tweaks and manipulations to make automated sessions more resemble real user sessions in browsers.

### Installation

First, ensure you have installed the necessary packages:

```bash
npm install express puppeteer puppeteer-extra puppeteer-extra-plugin-stealth
```

### Implementation

Below is a full example of how to integrate Puppeteer with the stealth plugin into your Express router to fetch and return the page title:

```javascript
const express = require('express');
const puppeteer = require('puppeteer-extra');
const StealthPlugin = require('puppeteer-extra-plugin-stealth');

puppeteer.use(StealthPlugin());

const router = express.Router();

router.get('/page-title', async (req, res) => {
  try {
    const browser = await puppeteer.launch({
      headless: true,
      args: [
        '--no-sandbox',
        '--disable-setuid-sandbox',
        '--disable-gpu',
        '--disable-dev-shm-usage',
        '--no-zygote',
        '--single-process',
        '--disable-gl-extensions',
        '--disable-accelerated-video-decode',
      ],
      ignoreHTTPSErrors: true,
    });

    const page = await browser.newPage();

    // Optimize page settings for faster loads and stealth usage.
    await page.setUserAgent('Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/58.0.3029.110 Safari/537.3');
    await page.setJavaScriptEnabled(true); 
    await page.setRequestInterception(true);

    page.on('request', (request) => {
      const resourceType = request.resourceType();
      if (['image', 'stylesheet', 'font'].includes(resourceType)) {
        request.abort();
      } else {
        request.continue();
      }
    });

    await page.goto('https://www.g2.com/products/asana/reviews', {
      waitUntil: 'domcontentloaded',
      timeout: 30000,
    });

    const pageTitle = await page.title();
    await browser.close();

    res.status(200).send(`Page title: ${pageTitle}`);
  } catch (error) {
    console.error(error);
    res.status(500).send('An error occurred while fetching the page title.');
  }
});

module.exports = router;
```

### Explanation

- **Puppeteer-Extra and Stealth Plugin**: By importing `puppeteer-extra` and using the `puppeteer-extra-plugin-stealth` plugin, the browser instance you create is equipped with various stealth features that mask Puppeteer's presence.
- **Page Configuration**:
  - **Request Interception**: Controls which resources are loaded, aborting requests for images, stylesheets, and fonts to optimize performance.
  - **User Agent Customization**: Sets a standard user agent to further disguise the automated usage.
  
### Main Server Integration

Finally, ensure your main server file integrates this router:

```javascript
const express = require('express');
const pageTitleRouter = require('./path-to-your-router-file');

const app = express();
const PORT = process.env.PORT || 3000;

app.use('/api', pageTitleRouter);

app.listen(PORT, () => {
  console.log(`Server is running on port ${PORT}`);
});
```

This setup should run without revealing Puppeteer's presence and efficiently fetch the page title.
user: convert this into the express router get /page-title: const express = require('express');
const app = express();
const port = process.env.PORT || 8000;
const cookieParser = require('cookie-parser')
const puppeteer = require('puppeteer-extra');
const StealthPlugin = require('puppeteer-extra-plugin-stealth');

puppeteer.use(StealthPlugin());

const { exec } = require('child_process');
app.use(express.json());
app.use(cookieParser());


exec('node node_modules/puppeteer/install.mjs', (error, stdout, stderr) => {
  if (error) {
    console.error(`Error: ${error}`);
    return;
  }

  console.log(`stdout: ${stdout}`);
  console.error(`stderr: ${stderr}`);
});

app.get('/', async (req, res) => {
  const url = req.query.url;
  if (!url) return res.send({ status: false, owner: 'SACHIBOT', err: 'Need site URL!' });

  try {
    const browser = await puppeteer.launch({
      headless: true,
      args: [
        '--no-sandbox',
        '--disable-setuid-sandbox',
        '--disable-dev-shm-usage',
        '--disable-accelerated-2d-canvas',
        '--disable-gpu',
      ],
    });

    let retries = 3;
    let html;
    while (retries > 0) {
      try {
        const page = await browser.newPage();
        await page.goto(url, { waitUntil: 'networkidle2', timeout: 60000 });
        html = await page.content();
        await browser.close();
        break;
      } catch (e) {
        console.error(`Attempt failed. Retries left: ${retries - 1}`);
        retries--;
        if (retries === 0) {
          throw e;
        }
      }
    }

    return res.status(200).send(html);
  } catch (e) {
    console.log(e);
    res.json({ error: e.message });
  }
});


app.listen(port, () => {
  console.log(`Server is running on port ${port}`);
});

    - Alternatively, download and install Google Chrome directly:
      ```bash
      wget https://dl.google.com/linux/direct/google-chrome-stable_current_amd64.deb
      sudo apt install ./google-chrome-stable_current_amd64.deb
      ```

2. **Set the `CHROME_PATH` Environment Variable:**
    - Find the path to the Chrome/Chromium executable. It could be something like `/usr/bin/google-chrome` or `/usr/bin/chromium-browser`.
    - Set the `CHROME_PATH` environment variable:
      ```bash
      export CHROME_PATH=/path/to/chrome
      ```
    - Alternatively, you can set this variable directly in your Node.js script before calling `connect`.

### Option 2: Use Puppeteer's Built-in Chromium
If you prefer not to install Chromium manually, you can opt for Puppeteer to use its bundled version:
1. **Switch to Puppeteer instead of Puppeteer-Core:**
   - If you're using `puppeteer-core` or another library like `puppeteer-real-browser`, switch to using `puppeteer`, which downloads a compatible Chromium version:
     ```bash
     npm uninstall puppeteer-real-browser
     npm install puppeteer
     ```

2. **Update Your Code to Use Puppeteer:**
   - Change the import and the connection method to use Puppeteer. Here's an example:

     ```javascript
     const express = require('express');
     const puppeteer = require('puppeteer');

     const router = express.Router();

     router.get('/page-title', async (req, res) => {
       try {
         const browser = await puppeteer.launch();
         const page = await browser.newPage();
        
         await page.goto('https://www.g2.com/products/asana/reviews', {
           waitUntil: "networkidle2"
         });
        
         const pageTitle = await page.title();
         await browser.close();

         res.status(200).send(`Page title: ${pageTitle}`);
       } catch (error) {
         console.error(error);
         res.status(500).send('An error occurred while fetching the page title.');
       }
     });

     module.exports = router;
     ```

### Additional Notes

- **Permissions:** Ensure that your user has the necessary permissions to install software and set environment variables on your VPS.
- **Headless Mode:** When running on a server without a GUI, make sure to run Puppeteer in headless mode (as shown in the code above with `await puppeteer.launch({ headless: true })`).

This should help you resolve the issue by ensuring that a Chromium browser is available for Puppeteer to use.
user: add all possible args to make this as efficient and fast as possible
assistant: To make Puppeteer as efficient and fast as possible, you can configure several options when launching the browser, as well as when navigating to a page. Here's how you might do that:

### Key Options for Efficiency:

1. **Headless Mode**: Ensure the browser runs in headless mode, which is faster because it doesn't render a UI.
2. **Disable Unnecessary Features**: Disable things like GPU hardware acceleration and images to save resources.
3. **Set a Specific User Agent**: This can sometimes help speed up page loads.
4. **Adjust Timeout Settings**: Customize timeouts to minimize unnecessary waits.
5. **Reduce Script Processing and Rendering**: Disable features that are not needed for your task.

Here’s how you can apply these optimizations:

```javascript
const express = require('express');
const puppeteer = require('puppeteer');

const router = express.Router();

router.get('/page-title', async (req, res) => {
  try {
    const browser = await puppeteer.launch({
      headless: true,
      args: [
        '--no-sandbox',  // Disables the sandbox for performance.
        '--disable-setuid-sandbox',  // For environments where setuid sandbox is not allowed.
        '--disable-gpu',  // Disables GPU hardware acceleration.
        '--disable-dev-shm-usage',  // Uses /tmp dir instead of /dev/shm (more space).
        '--no-zygote',  // Helps to prevent resource restrictions on some Linux distributions.
        '--single-process',  // Runs everything in a single process for memory optimization.
        '--disable-gl-extensions', // Disables unnecessary graphic extensions.
        '--disable-accelerated-video-decode',  // Reduces load related to video processing.
      ],
      ignoreHTTPSErrors: true,  // Ignores HTTPS errors to proceed with navigation.
    });

    const page = await browser.newPage();

    // Optimize page settings for faster loads.
    await page.setUserAgent('Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/58.0.3029.110 Safari/537.3');
    await page.setJavaScriptEnabled(true);  // Ensure JavaScript is enabled as needed.
    await page.setRequestInterception(true);

    // Intercept requests to disable images and other resource types that are not needed.
    page.on('request', (request) => {
      const resourceType = request.resourceType();
      if (['image', 'stylesheet', 'font'].includes(resourceType)) {
        request.abort();
      } else {
        request.continue();
      }
    });

    await page.goto('https://www.g2.com/products/asana/reviews', {
      waitUntil: 'domcontentloaded',  // Ensures HTML is loaded without waiting for full resources.
      timeout: 30000,  // Set timeout to 30 seconds to avoid prolonged waits.
    });

    const pageTitle = await page.title();  // Get the page title
    await browser.close();

    res.status(200).send(`Page title: ${pageTitle}`);
  } catch (error) {
    console.error(error);
    res.status(500).send('An error occurred while fetching the page title.');
  }
});

module.exports = router;
```

### Additional Considerations:
- **Resource Management**: Manage caching and cookies if frequent visits to similar pages are needed.
- **Environment**: Make sure the environment (like a VPS) has sufficient CPU and memory.
- **Concurrency**: If processing multiple pages, limit concurrency to avoid CPU overload.

These optimizations should help improve the speed and efficiency of your Puppeteer script by focusing on the tasks critical to your needs while avoiding unnecessary processing.
user: use puppeteer stealth
assistant: To enhance Puppeteer's ability to avoid detection as an automated tool, you can utilize the `puppeteer-extra` package along with its `puppeteer-extra-plugin-stealth` plugin. This setup helps disguise Puppeteer's activities by applying various tweaks and manipulations to make automated sessions more resemble real user sessions in browsers.

### Installation

First, ensure you have installed the necessary packages:

```bash
npm install express puppeteer puppeteer-extra puppeteer-extra-plugin-stealth
```

### Implementation

Below is a full example of how to integrate Puppeteer with the stealth plugin into your Express router to fetch and return the page title:

```javascript
const express = require('express');
const puppeteer = require('puppeteer-extra');
const StealthPlugin = require('puppeteer-extra-plugin-stealth');

puppeteer.use(StealthPlugin());

const router = express.Router();

router.get('/page-title', async (req, res) => {
  try {
    const browser = await puppeteer.launch({
      headless: true,
      args: [
        '--no-sandbox',
        '--disable-setuid-sandbox',
        '--disable-gpu',
        '--disable-dev-shm-usage',
        '--no-zygote',
        '--single-process',
        '--disable-gl-extensions',
        '--disable-accelerated-video-decode',
      ],
      ignoreHTTPSErrors: true,
    });

    const page = await browser.newPage();

    // Optimize page settings for faster loads and stealth usage.
    await page.setUserAgent('Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/58.0.3029.110 Safari/537.3');
    await page.setJavaScriptEnabled(true); 
    await page.setRequestInterception(true);

    page.on('request', (request) => {
      const resourceType = request.resourceType();
      if (['image', 'stylesheet', 'font'].includes(resourceType)) {
        request.abort();
      } else {
        request.continue();
      }
    });

    await page.goto('https://www.g2.com/products/asana/reviews', {
      waitUntil: 'domcontentloaded',
      timeout: 30000,
    });

    const pageTitle = await page.title();
    await browser.close();

    res.status(200).send(`Page title: ${pageTitle}`);
  } catch (error) {
    console.error(error);
    res.status(500).send('An error occurred while fetching the page title.');
  }
});

module.exports = router;
```

### Explanation

- **Puppeteer-Extra and Stealth Plugin**: By importing `puppeteer-extra` and using the `puppeteer-extra-plugin-stealth` plugin, the browser instance you create is equipped with various stealth features that mask Puppeteer's presence.
- **Page Configuration**:
  - **Request Interception**: Controls which resources are loaded, aborting requests for images, stylesheets, and fonts to optimize performance.
  - **User Agent Customization**: Sets a standard user agent to further disguise the automated usage.
  
### Main Server Integration

Finally, ensure your main server file integrates this router:

```javascript
const express = require('express');
const pageTitleRouter = require('./path-to-your-router-file');

const app = express();
const PORT = process.env.PORT || 3000;

app.use('/api', pageTitleRouter);

app.listen(PORT, () => {
  console.log(`Server is running on port ${PORT}`);
});
```

This setup should run without revealing Puppeteer's presence and efficiently fetch the page title.
user: convert this into the express router get /page-title: const express = require('express');
const app = express();
const port = process.env.PORT || 8000;
const cookieParser = require('cookie-parser')
const puppeteer = require('puppeteer-extra');
const StealthPlugin = require('puppeteer-extra-plugin-stealth');

puppeteer.use(StealthPlugin());

const { exec } = require('child_process');
app.use(express.json());
app.use(cookieParser());


exec('node node_modules/puppeteer/install.mjs', (error, stdout, stderr) => {
  if (error) {
    console.error(`Error: ${error}`);
    return;
  }

  console.log(`stdout: ${stdout}`);
  console.error(`stderr: ${stderr}`);
});

app.get('/', async (req, res) => {
  const url = req.query.url;
  if (!url) return res.send({ status: false, owner: 'SACHIBOT', err: 'Need site URL!' });

  try {
    const browser = await puppeteer.launch({
      headless: true,
      args: [
        '--no-sandbox',
        '--disable-setuid-sandbox',
        '--disable-dev-shm-usage',
        '--disable-accelerated-2d-canvas',
        '--disable-gpu',
      ],
    });

    let retries = 3;
    let html;
    while (retries > 0) {
      try {
        const page = await browser.newPage();
        await page.goto(url, { waitUntil: 'networkidle2', timeout: 60000 });
        html = await page.content();
        await browser.close();
        break;
      } catch (e) {
        console.error(`Attempt failed. Retries left: ${retries - 1}`);
        retries--;
        if (retries === 0) {
          throw e;
        }
      }
    }

    return res.status(200).send(html);
  } catch (e) {
    console.log(e);
    res.json({ error: e.message });
  }
});


app.listen(port, () => {
  console.log(`Server is running on port ${port}`);
});
