This example demonstrates how to use webpack-dev-server.

npx webpack serve --open

To run your app using an alternative config, use:

npx webpack serve --open --config alternative.config.js

1. The script should open http://localhost:8080/ in your default browser.
2. You should see the text on the page itself change to read Success!.
3. In app.js uncomment the code that results in an error and save.
4. This error should be visible in the console/terminal and in the browser's devtools.
5. In app.js uncomment the code that results in a warning. This warning should be visible in the console/terminal and in the browser's devtools.
6. Try changing something in style.less. The browser should refresh, and the change should be visible in the app.
