I spent about an hour digging around yesterday and couldn't find the answer to this question, so I wanted to post here and get some insight.

I read through #516, which seems to indicate there is HTTP/2 supported, but I couldn't find any docs on how to enable it. All I found in the official docs was the line under this section https://webpack.js.org/configuration/dev-server/#devserverhttps saying that it can run with HTTP/2.

In the code in this repo I found this

webpack-dev-server/lib/Server.js

Lines 633 to 660 in 21687c3

if (!options.https.spdy) {
options.https.spdy = {
protocols: ['h2', 'http/1.1'],
};
}
// `spdy` is effectively unmaintained, and as a consequence of an
// implementation that extensively relies on Node’s non-public APIs, broken
// on Node 10 and above. In those cases, only https will be used for now.
// Once express supports Node's built-in HTTP/2 support, migrating over to
// that should be the best way to go.
// The relevant issues are:
// - https://github.com/nodejs/node/issues/21665
// - https://github.com/webpack/webpack-dev-server/issues/1449
// - https://github.com/expressjs/express/issues/3388
if (semver.gte(process.version, '10.0.0')) {
this.listeningApp = https.createServer(options.https, app);
} else {
/* eslint-disable global-require */
// The relevant issues are:
// https://github.com/spdy-http2/node-spdy/issues/350
// https://github.com/webpack/webpack-dev-server/issues/1592
this.listeningApp = require('spdy').createServer(options.https, app);
/* eslint-enable global-require */
}
} else {
this.listeningApp = http.createServer(app);
}

All of which links to issues and other repos which have either been closed or have no work being done on them. And according to this comment #1493 (comment), it is planned for v4, but nothing in the 4.0.0 milestone https://github.com/webpack/webpack-dev-server/milestone/4 seems to support that statement.

Ultimately, I'm confused as to the current situation. Does Webpack-Dev-Server support HTTP/2? If not, will it be supported in the future?
