hotUpdate

Option: hotUpdate

Type: boolean Default: false

If the value is true, then in the serve or watch mode, the hot-update.js file is injected into each generated HTML file to enable the live reloading. Use this options only if you don't have a referenced source file of a script in template.

note

The devServer.hot must be true.

If you already have a JS file in HTML, this setting should be false as Webpack automatically injects the hot update code into the compiled JS file.
