Hot mode still supported?

[jhnns]

Is the hot mode still supported? It seems like hot is always false in

webpack-dev-server/client/index.js

Line 8 in 3932f64

var hot = false;

I'm trying to set up the hot mode with an inlined webpack-dev-server using the style-loader. The client receives the hot event and the webpack config has the HotModuleReplacementPlugin applied, but the styles are not replaced.

Thx for the quick fix. But it's still not working.
What happens after window.postMessage("webpackHotUpdate", "*");?

You need to add "webpack/hot/dev-server" as entry. This module triggers the hot update.

This page should be linked in the documentation, but it isn't :(

Yep, that's it! Thx.

That's my setup:

function configureDevWebpack(app) {
    var Server = require("webpack-dev-server"),
        webpackConfig = require("../../config/webpack.config"),
        config = require("../../config"),
        webpack = require("webpack"),
        compiler,
        devServerOptions,
        server;

    devServerOptions = {
        hot: true,
        contentBase: "http://vagrant.vm:" + config.port
    };
    webpackConfig.entry.unshift(
        require.resolve("webpack-dev-server/client") + "?http://vagrant.vm:" + webpackDevServerPort,
        require.resolve("webpack/hot/dev-server")
    );

    compiler = webpack(webpackConfig);
    server = new Server(compiler, devServerOptions);
    server.listen(webpackDevServerPort, function (err) {
        if (err) {
            throw err;
        }
        console.log("webpack-dev-server is listening on " + webpackDevServerPort);
    });
    app.use(server.middleware);
}

I think this could be useful for other users too.
