Description
Do you want to request a feature or report a bug?
feature
What is the current behavior?
server.listen(0, '127.0.0.1', () => {
// port will automaticly assign to a free port.
});What is the expected behavior?
server.listen(0, '127.0.0.1', () => {});
server.once('listening', () => {
// while running we want to request the used port number.
const port = server.address().port;
});If this is a feature request, what is motivation or use case for changing the behavior?
I use webpack-dev-server to serve my application for browser-test. I want webpack to use a free port and after serving to tell my browser-test where to find the test-pages.
Please mention your webpack and Operating System version.
webpack: 3.3.0
webpack-dev-server: 2.5.1
