webpack-dev-server-waitpage

Webpack progress wait page for webpack-dev-server

Instead of waiting for webpack to finish compiling, see a nice progress wait page.

Installation

npm

npm install -D webpack-dev-server-waitpage

yarn

yarn add -D webpack-dev-server-waitpage

Usage

webpack.config.js

1 - Add the plugin to the plugins array:

const webpackDevServerWaitpage = require('webpack-dev-server-waitpage');

...
  plugins: [
     ...

     webpackDevServerWaitpage.plugin(),
  
     ...
  ] 

...

Note: Arguments for the plugin method are the same as the object that can be passed to ProgressPlugin besides the handler function which is used internally (it is best to leave it blank).

2 - Inside the before/onBeforeSetupMiddleware (depending on which version of webpack-dev-server you are using) option function of devServer enter the following line as in the example below:

webpack-dev-server@3

const webpackDevServerWaitpage = require('webpack-dev-server-waitpage');

...

  devServer: {
    before: (app, server) => {

      // Be sure to pass the server argument from the arguments
      app.use(webpackDevServerWaitpage(server));

    }
  }

webpack-dev-server@4

const webpackDevServerWaitpage = require('webpack-dev-server-waitpage');

...

  devServer: {
    onBeforeSetupMiddleware: server => {

      // Be sure to pass the server argument from the arguments
      server.app.use(webpackDevServerWaitpage(server, { theme: "material" }));

    }
  }

You can also provide options object for the middleware as a second parameter (i.e. app.use(webpackDevServerWaitpage(options, {})) or omit it.

Middleware options

Option	Description	Type	Default Value
`title`	The window title	`String`	`"Development Server"`
`theme`	Use a predefined theme (Options are: `"default"`, `"dark"`, `"material"`)	`String`	`"default"`
`template`	Provide an alternative `ejs` template (overrides the `theme` option)	`String`	The predefined template used by the `theme` option
`disableWhenValid`	Whether to stop showing the waitPage after the first compilation (otherwise, will continue to show on hot full page reloads)	`Boolean`	`true`
`ignore`	Rules to ignore certain url or requests. (String and RegExp are matched vs req.url, while Functions gets the express request as argument)	`string / RegExp / Function<Request>:Boolean / Array<string/RegExp/Function>`	`null`

These and any other option would be passed to the global scope of the ejs template.

Themes

There are other themes to choose from:

Dark

Material

* And you can also create your own! *

Developing a new template

You can clone this repository and use the script test to help you develop a new template.

Create a new ejs file (e.g. my-theme.ejs)
Change the webpack.config.js filename argument of testMiddleware to yours (e.g. testMiddleware('my-theme.ejs')).
Run npm t

Template data object

The ejs renderer gets a data object with the following values:

{
    title: "Development Server", // the window title
    webpackVersion: "4.0.0", // currently used webpack version
    webpackDevServerVersion: "1.0.0", // currently used webpack-dev-server version
    progress: [ // number of object as number of webpack configurations
      [
        0.5, // progress between 0 to 1
        "message", // message from webpack
        "0/1000", // modules progress message
        "0 active", // active modules message
        "<some path>" // path of current module
      ]
    ]
}
