PyInstaller with Playwright and Firefox

What will you learn?

In this tutorial, you will learn how to utilize PyInstaller to package a Python script that incorporates Playwright with Firefox for efficient web automation.

Introduction to the Problem and Solution

When it comes to converting Python scripts into standalone executables using PyInstaller, additional considerations need to be taken into account when working with browser automation libraries like Playwright. The challenge lies in ensuring that the packaged application includes all the necessary dependencies, including the essential browser binaries required by Playwright.

To address this issue effectively, we will delve into configuring PyInstaller properly to incorporate the Playwright dependencies and Firefox binaries while creating the executable.

Code

# Import necessary libraries
import playwright.sync_api as sync_playwright

# Create a function for web automation using Playwright with Firefox
def automate_with_playwright():
    # Initialize Playwright context with Firefox browser
    with sync_playwright().firefox.launch() as browser:
        page = browser.new_page()

        # Implement web automation tasks here

if __name__ == '__main__':
    automate_with_playwright()

Explanation

When combining PyInstaller with Playwirght and Firefox, it’s crucial to explicitly specify additional files and folders that should be included in the packaged executable. This guarantees that all dependencies are bundled correctly.

  1. Specifying Additional Files: Utilize PyInstaller’s –add-binary flag along with specifying data files via datas in your spec file.
  2. Including Browser Binaries: For a successful Playwirght + Firefox setup, ensure the inclusion of necessary binary files from both packages.

By following these steps meticulously, you can create an executable of your Python script seamlessly integrating Playwirght with Firefox for web automation tasks.
