Electron

Playwright has experimental support for Electron automation. You can access electron namespace via:

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

An example of the Electron automation script would be:

const { _electron: electron } = require('playwright');

(async () => {
  // Launch Electron app.
  const electronApp = await electron.launch({ args: ['main.js'] });

  // Evaluation expression in the Electron context.
  const appPath = await electronApp.evaluate(async ({ app }) => {
    // This runs in the main Electron process, parameter here is always
    // the result of the require('electron') in the main app script.
    return app.getAppPath();
  });
  console.log(appPath);

  // Get the first window that the app opens, wait if necessary.
  const window = await electronApp.firstWindow();
  // Print the title.
  console.log(await window.title());
  // Capture a screenshot.
  await window.screenshot({ path: 'intro.png' });
  // Direct Electron console to Node terminal.
  window.on('console', console.log);
  // Click button.
  await window.click('text=Click me');
  // Exit app.
  await electronApp.close();
})();

Supported Electron versions are:

v12.2.0+
v13.4.0+
v14+

Known issues:

If you are not able to launch Electron and it will end up in timeouts during launch, try the following:

Ensure that nodeCliInspect (FuseV1Options.EnableNodeCliInspectArguments) fuse is not set to false.

Methods

launch

Added in: v1.9

electron.launch

Launches electron application specified with the executablePath.

Usage

    Optional setting to control whether to omit request content from the HAR. Defaults to false. Deprecated, use content policy instead.
  - content "omit" | "embed" | "attach" (optional)
    
    Optional setting to control resource content management. If omit is specified, content is not persisted. If attach is specified, resources are persisted as separate files or entries in the ZIP archive. If embed is specified, content is stored inline the HAR file as per HAR specification. Defaults to attach for .zip output files and to embed for all other file extensions.
  - path string
    
    Path on the filesystem to write the HAR file to. If the file name ends with .zip, content: 'attach' is used by default.
  - mode "full" | "minimal" (optional)
    
    When set to minimal, only record information necessary for routing from HAR. This omits sizes, timing, page, cookies, security and other types of HAR information that are not used when replaying from HAR. Defaults to full.
  - urlFilter string | RegExp (optional)
    
    A glob or regex pattern to filter requests that are stored in the HAR. When a baseURL via the context options was provided and the passed URL is a path, it gets merged via the new URL() constructor. Defaults to none.
  Enables HAR recording for all pages into recordHar.path file. If not specified, the HAR is not recorded. Make sure to await browserContext.close() for the HAR to be saved.
