Enables Hot Module Replacement, otherwise known as HMR.
HMR should never be used in production.
Enabling HMR is easy and in most cases no options are necessary.
new webpack.HotModuleReplacementPlugin({
// Options...
})
The following options are accepted:
multiStep (boolean): If true, the plugin will build in two steps -- first compiling the hot update chunks, and then the remaining normal assets.fullBuildTimeout (number): The delay between the two steps when multiStep is enabled.requestTimeout (number): The timeout used for manifest download (since webpack 3.0.0)These options are experimental and may be deprecated. As mentioned above, they are typically not necessary and including anew webpack.HotModuleReplacementPlugin()is enough.
