How to Set Up Playwright with TypeScript

TL;DR

Install Node.js and npm, open a project folder in Visual Studio Code, then run the Playwright initialization command from that folder's terminal. Select TypeScript, choose a test directory, decide whether to add a GitHub Actions workflow, and allow the installer to download the Chromium, Firefox, and WebKit browsers.

hey guys this is Naia welcome back to na automation Labs so with this video we are going to start a new series with playright JavaScript and typescript just like we do other programming languages with selenium or some other tools are there we always learn about the specific language and then we cover the tool specific part because in the tool you h...

Key Insights

• Node.js is a mandatory part of this Playwright setup because the JavaScript and TypeScript version of Playwright operates through Node.js. Installing Node.js also provides npm, which is used to download the packages needed for the automation project.
• The Node.js installation is verified by opening Command Prompt and running the Node version command. The demonstrated machine reports Node version 18, while the accompanying npm version is shown as 9.5.1, confirming that both tools are available.
• Visual Studio Code is the recommended editor in the walkthrough because it is designed for JavaScript-based projects and offers useful extensions and plugins. Eclipse and IntelliJ are discouraged for this particular setup in favor of Visual Studio Code.
• A dedicated project folder is the starting location for Playwright installation. The folder can be created anywhere, opened through Visual Studio Code, and used as the current directory in the integrated terminal before the Playwright initialization command is executed.
• The Playwright initializer is run through npm using the latest package version. It prompts for permission to download the required package, then guides the user through language selection, test-folder configuration, workflow setup, and browser installation.
• TypeScript is the default language offered by the Playwright initialization process in the demonstration. The user can switch between TypeScript and JavaScript with the arrow keys before confirming which language the generated project should use.
• Playwright supports Chromium, Firefox, and WebKit browser engines according to the walkthrough. Its tests can run in headed or headless mode and on Windows, Linux, or Mac, with support for local execution and continuous integration.
• Programming fundamentals are necessary for effective Playwright automation because realistic tests require logic beyond tool commands. Loops, conditions, strings, arrays, functions, objects, method calls, parameters, and iteration are specifically identified as important JavaScript concepts to understand.

Questions & Answers

Q: How do you install Playwright with TypeScript on Windows?

Install Node.js first, which also installs npm, and verify both tools from Command Prompt. Next, install Visual Studio Code, create a dedicated project folder, and open that folder in the editor. Launch the integrated terminal and run the Playwright initialization command for the latest package. Choose TypeScript, select the test folder, answer the GitHub Actions prompt, and approve installation of the Playwright browsers.

Q: Why is Node.js required for Playwright with TypeScript?

Node.js is required because the JavaScript and TypeScript version of Playwright works through the Node.js environment. It enables the project to use Playwright libraries and interact with browsers. The Node.js installation also includes npm, the package manager used to download Playwright and other JavaScript-based packages needed by the automation project.

Q: How can you verify that Node.js and npm are installed?

Open Command Prompt after completing the Node.js installation and run the Node version command. The demonstration shows Node version 18 as the installed result. Because npm is supplied with Node.js, its version can also be checked from the command line. The walkthrough displays npm version 9.5.1, confirming that the package manager is available for installing Playwright.

Q: How do you create a Playwright project in Visual Studio Code?

Create a new folder in any suitable location, such as the demonstrated Playwright demo folder on the C drive. In Visual Studio Code, choose the option to open a folder, select the new directory, and confirm that you trust its authors when prompted. Open the integrated terminal, verify that it points to the selected directory, and execute the Playwright initialization command there.

Q: Which options appear during Playwright project initialization?

The initializer first asks for approval to download the Playwright creation package. It then asks whether the project should use TypeScript or JavaScript, with TypeScript shown as the default. Additional prompts request the folder for end-to-end tests, whether a GitHub Actions workflow should be added, and whether the Playwright browsers should be installed during setup.

Q: Which browsers can Playwright install for testing?

The setup can install Chromium, Firefox, and WebKit for Playwright testing. The walkthrough associates WebKit with Apple and identifies Chrome and Microsoft Edge as Chromium-based browsers. Browser installation can be approved during project initialization or completed later with the separate Playwright install command. The demonstration chooses to download all three browser engines during the initial setup.

Q: How much JavaScript knowledge is needed before learning Playwright?

A basic understanding of JavaScript or TypeScript is strongly recommended before writing Playwright automation. The relevant fundamentals include loops, conditional logic, strings, arrays, functions, objects, method calls, parameters, and array iteration. These skills are needed to build test logic and reusable functions, such as code that handles a web table with pagination.

Q: Can Playwright tests run in headless mode and continuous integration?

Playwright tests can run in both headless and headed modes according to the walkthrough. The tool supports Windows, Linux, and Mac, and tests can run locally or through continuous integration. Jenkins and GitHub Actions are mentioned as integration options. During initialization, the user can choose whether to add a GitHub Actions workflow to the generated project.

Summary & Key Takeaways

• Playwright with TypeScript requires Node.js and npm on the Windows machine. After installing Node.js, open Command Prompt and check the installation with the Node version command. The npm package manager is installed alongside Node.js and is used to download the JavaScript packages required by the Playwright project.

• Visual Studio Code is used as the editor for the project because it supports JavaScript development, extensions, and plugins. Create a dedicated Playwright project folder, open that folder in Visual Studio Code, and use its integrated terminal so the initialization command creates all project files in the intended directory.

• Run the Playwright initialization command from the project folder and approve the requested package download. Choose TypeScript or JavaScript, specify the test folder, decide whether to add a GitHub Actions workflow, and approve browser installation. The setup then downloads Playwright browsers, including Chromium, Firefox, and WebKit.

• Basic JavaScript or TypeScript knowledge should come before serious Playwright development. Functions, arrays, objects, loops, conditions, strings, parameters, and iteration are needed for writing reusable automation logic. Without those fundamentals, tasks such as implementing pagination for a web table become difficult even when Playwright itself is installed correctly.
