For Bugs; How can we reproduce the behavior?

For Features; What is the motivation and/or use-case for the feature?

Inspired on create-react-app solution.

Since I usually use Google Chrome, I expect to stay in the same (current) browser tab
when re-launch webpack-dev-server, instead of use a new one and close those more.

Just curious if the Webpack people/ecosystem are interested in having this behaviour (will PR in case), since is very specific to Chrome browser in OSX platform.

Furthermore, the solution requires to have an extra file .applescript in the package.

Thoughts?

related #1185

The request concerns webpack-dev-server's browser-launch behavior and mentions webpack.config.js plus an extra .applescript file. Start by reading related issue #1185 and tracing how the server opens the browser on OSX. Done means relaunching webpack-dev-server reuses the current Chrome tab instead of opening another one, without breaking other platforms.
