• Linux: For Linux users, Puppeteer installs Chromium in the user’s home directory, within the ~/.npm/_npx folder.

It’s worth noting that Puppeteer installs a version of Chromium that is compatible with the specific version of Puppeteer you are using. This ensures that you have a consistent and reliable browser environment that works seamlessly with Puppeteer’s API.

Customizing Chromium Installation Path

In some cases, you may want to customize the installation path of Chromium. Puppeteer provides an option to specify a custom installation path using the executablePath property when launching a browser instance. This allows you to use a specific version of Chromium or use a pre-installed version on your system.

Here’s an example of how you can specify a custom installation path:

“`javascript
const puppeteer = require(‘puppeteer’);

(async () => {
const browser = await puppeteer.launch({
executablePath: ‘/path/to/chromium’,
});
// Rest of your Puppeteer code
})();
“`

In the example above, you need to replace /path/to/chromium with the actual path to your Chromium installation. This way, Puppeteer will use the specified Chromium instance instead of the default one it installs.

Verifying Chromium Installation

To verify that Puppeteer has installed Chromium correctly, you can use the executablePath() method provided by Puppeteer. This method returns the path to the Chromium executable being used by Puppeteer.

Here’s an example:

“`javascript
const puppeteer = require(‘puppeteer’);

(async () => {
const browser = await puppeteer.launch();
const executablePath = puppeteer.executablePath();
console.log(Chromium is installed at: ${executablePath});
await browser.close();
})();
“`

When you run the above code, it will output the path to the Chromium executable being used by Puppeteer. This confirms that Puppeteer has successfully installed Chromium and is ready to be used for browser automation or web scraping.

In conclusion, Puppeteer automatically installs Chromium for you when you install the library using npm. It takes care of all the necessary dependencies and ensures a consistent browser environment. You can also customize the installation path of Chromium if needed. Verifying the installation is straightforward using the executablePath() method provided by Puppeteer. With Puppeteer and Chromium, you have a powerful combination for automating browser tasks and extracting data from websites.

Now that we have our project set up, let’s install Puppeteer. Run the following command in your terminal to install Puppeteer as a dependency for your project:

bash
npm install puppeteer

This command will download and install the latest version of Puppeteer from the npm registry.

Step 4: Test Puppeteer Installation

To verify that Puppeteer has been installed successfully, let’s write a simple script to open a new browser page using Puppeteer. Create a new file called “index.js” in your project directory and add the following code:

“`javascript
const puppeteer = require(‘puppeteer’);

(async () => {
const browser = await puppeteer.launch();
const page = await browser.newPage();
await page.goto(‘https://www.example.com’);
await browser.close();
})();
“`

Save the file and run the following command in your terminal to execute the script:

bash
node index.js

If everything is set up correctly, Puppeteer will launch a headless Chrome browser, open the example.com website, and then close the browser.

Congratulations! You have successfully installed Puppeteer on Ubuntu 20.04 and tested its installation.
