Drive-by: bump playwright-electron version to 0.4.0; i'll publish it after this PR lands.
playwright-electron
This package contains the Electron flavor of Playwright.
How to demo
npm i --save-dev electron@beta playwright-electron
npx mocha
index.js - main Electron application file.
const { app, BrowserWindow } = require('electron');
function createWindow () {
let win = new BrowserWindow({
width: 800,
height: 600,
});
win.loadFile('index.html');
}
app.whenReady().then(createWindow);
index.html - page that Electron opens in a BrowserWindow.
<!DOCTYPE html>

<head>
<meta charset="UTF-8">
