I am writing a visual studio code extension and I'd like to be able to open a browser window with a specific url in response to a command. I know that Electron has a BrowserWindow class but it appears that the Electron API is not accessible from a vscode extension.
I'd prefer the browser window to open within the tool but I'd be ok with opening the web page in my default browser if it is not possible.
How does one open a web page from an extension?

This was added recently (see microsoft/vscode#109276).

To open a browser window inside VS Code you can use the WebView API, though you need to supply HTML content rather than a URL:
export function activate(context: vscode.ExtensionContext) { context.subscriptions.push( vscode.commands.registerCommand('catCoding.start', () => { // Create and show panel const panel = vscode.window.createWebviewPanel( 'catCoding', 'Cat Coding', vscode.ViewColumn.One, {} ); // And set its HTML content panel.webview.html = getWebviewContent(); }) ); } function getWebviewContent() { return `<!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <meta name="viewport" content="width=device-width, initial-scale=1.0"> <title>Cat Coding</title> </head> <body> <img src="https://media.giphy.com/media/JIX9t2j0ZTN9S/giphy.gif" width="300" /> </body> </html>`; } 
Depending on your specific use case, there's also the Browser Preview extension which registers a command browser-preview.openPreview that you could use (you'd probably want to list browser-preview as a dependency to ensure it's installed).
And finally, if you just want to open in a normal browser window you can use the env.openExternal API. When running in remote environments this will also take care of exposing ports and mapping to the exposed hostname (if it's a localhost-served service):
vscode.env.openExternal(Uri.parse("https://www.stackoverflow.com/")); If you love us? You can donate to us via Paypal or buy me a coffee so we can maintain and grow! Thank you!
