How to Install Playwright: Step-by-Step Installation Guide

If you are looking to set up Playwright for the first time, this guide walks you through the complete installation process from setting up Node.js to running your first Playwright script.

Below, we cover the key benefits of Playwright, a step-by-step installation guide, and how to write and execute your first script.

What is Playwright?

Playwright is an open-source browser automation library developed by Microsoft. It allows you to automate browser interactions across Chromium, Firefox, and WebKit using a single, unified API. Whether you are writing end-to-end tests, scraping web data, or validating UI flows, Playwright handles it all from one framework.

What makes Playwright stand out is its ability to work across multiple browsers, operating systems, and programming languages without requiring separate configurations for each. It is designed to be fast, reliable, and easy to set up, which is exactly what this guide walks you through.

Now, before jumping into the installation, let’s make sure your system has everything it needs.

Prerequisites

Before starting with the Playwright installation, make sure your system meets the following requirements:

• Operating System: Windows, macOS, or Linux
• Node.js: Version 14 or above
• npm: Comes bundled with Node.js
• Code Editor: Visual Studio Code is recommended for writing and managing Playwright scripts

Benefits of Playwright

There are various benefits of working with a playwright as the primary framework of test automation in a testing project.

1. Single API: As we need to perform automation for multiple browsers, Playwright helps in achieving this by providing a single API for major browser engines. It simplifies the process of writing and maintaining test automation scripts.

2. Fast and Reliable: Playwright is competitively faster than all the available frameworks in the market, because of the predefined library it uses. This behavior of the playwright makes it more suitable for automated testing and web scraping tasks

3. Headless and Headful Modes: Playwright allows automaters to run scripts in both headless and headful modes to see the behaviour of the application. It supports automation of complex tasks such as handling network requests and interacting with iframes. We can emulate devices to check applications and their behaviour on different devices.

4. Cross-Platform: Another important feature of Playwright is its ability to execute across platforms; it works seamlessly over macOS, Linux, and Windows.

5. Built-in wait mechanism & reporting: Playwright comes with a built-in wait mechanism for particular conditions, such as an element appearing or disappearing on the webpage. It helps in making scripts to handle dynamic web elements.
   For reporting purposes, Playwright gives multiple options, such as taking screenshots and recording videos of the execution, which makes it easy to understand what went wrong.

6. Languages: Playwright supports multiple programming languages such as JavaScript, TypeScript, C#, and Python. With this flexibility, it becomes user-friendly for all users coming from different backgrounds.

Playwright Installation Guide

Below are the steps for performing Playwright installation on a Windows machine:

Step 1: Installation of Node.js

Playwright runs on Node.js, so Node.js must be installed on your system before proceeding. We can do this using the official website and download the latest version (https://nodejs.org/), after installing it be can validate the installation status using a command on the terminal.

node -v
npm -v
// These commands will display installed Node.js and npm versions

Step 2: Create a New Node.js Project

In this step, we will be creating a new directory for the playwright project and navigating to it using the terminal.

mkdir my-playwright-project
cd my-playwright-project
npm init -y

The above commands will create a new Node.js project with a `package.json` file.

Step 3: Install Playwright

Below are the commands for Playwright installation. Depending on the usage, if a user wants to install it for using Chrome, they can use the commands for Chromium, and similarly, others can be used.

For Chromium (recommended for most use cases):
npm install playwright

For Firefox:
npm install playwright-firefox

For WebKit:
npm install playwright-webkit

Step 4: Write Your First Playwright Script

For writing the first script, we first need to create a JavaScript or TypeScript file.

We will write the code below, using which we can access the browser and open a web URL.

First, we are invoking the browser API and then passing the web URL that we want to open, and finally closing the browser.

const { chromium } = require('playwright');

(async () => {
  const browser = await chromium.launch();
  const page = await browser.newPage();
  await page.goto('https://example.com');
  await browser.close();
})();

Step 5: Run Your Playwright Script

Using the command below, we can execute the script that we wrote to open a web URL in a web browser and finally close it.

node your-script.js

Playwright vs Cypress – Which One Should You Choose?

This is one of the most common questions that comes into the picture while selecting a framework for creating a test automation framework. We will try to answer this in brief in this article.

Users should use Playwright when they want to perform cross-browser testing, interact with multiple pages, if they are trying to accommodate network interaction, and if they want to use multiple programming languages across the test automation. For performing comprehensive test automation, Playwright is the best choice.

Whereas Cypress should be used when a user wants to work primarily with the Chrome browser, and the preferred scripting language is JavaScript. Cypress is more suitable for end-to-end automation, real-time reloading, and debugging.

Integrating Playwright with CI/CD Tools

Integration of the Playwright project with the CI/CD tool is very important, as it ensures that automated tests will start executing automatically whenever there is a change in the codebase, which overall helps in improving the quality of the product, as we will get continued feedback.

To perform this, first we need to choose a good CI/CD tool such as Jenkins or GitHub, then we will set up the environment and install the required dependencies. Then we will have version-controlling tools such as GitHub, which will help in having an updated codebase, then we will be creating test configurations, and finally test execution will happen from the updated branch.

Is Playwright the Future of Browser Automation?

We always try to find an answer to the question: Is Playwright the future of Browser Automation? The absolute answer is that it depends on the growth of Automation testing in the industry. For a very long time, WebDriver Tools have been present in the market to solve all the problems related to it. 

Choosing between Playwright and Cypress is subjective to the situation or problem they will be used for, as both have their own advantages and limitations associated.

As Playwright is fairly new to the market, support related to the issues that are arising while writing automation is very limited; support pages, websites, and groups are not that active as compared to other test automation communities.

However, each of the automation frameworks supports CI/CD for a software project with due accuracy. Playwright has an advantage for automating complex web applications, but it has limited coverage. On the contrary, Selenium offers wide scalability and coverage along with strong community support for test automation issues.

Limitations of Playwright

Playwright test automation framework is a very powerful test automation framework, but it has a few limitations, which are listed below.

1. Limited browser support.
2. Limited community and documentation.
3. Performance limitations with large-scale applications.
4. Integration limitations with some existing tools.

We should understand the fact that these limitations don’t make a playwright a bad choice for test automation. Instead, these are just observations that the user should consider while finalizing the framework for test automation requirements specific to the project and web application.
