Ways to update web pack public path

1. For Apps using create-react-app, add the homepage in package.json to change public path.

   "homepage": "/new-public-path",

   Also, this support relative path.

   "homepage": ".",

   Another way is define PUBLIC_URL environment variable somewhere in your build pipeline.

2. Webpack now provide config to change public path. See webpack guide page. In webpack config file set output:

   output: {
     publicPath: '/some-path'
   },

3. Change webpack public path on the fly.

   Webpack prefined a variable __webpack_public_path__.

   __webpack_public_path__ = window.location.pathname;

   This variable will be replaced by webpack_require.p in build time, that's how webpack changes the public path.

Configuration

const UpdatePublicPathPlugin = require("webpack-update-public-path-plugin")

    plugins: [
        ...
        new UpdatePublicPathPlugin({
            publicPath: JSON.stringify('/foo/bar/')
        })
        ...
    ]

After build

The following line will be added

/******/        __webpack_require__.p = '/foo/bar';

after

/******/        // __webpack_public_path__
/******/        __webpack_require__.p = "/";

Public path is changed to '/foo/bar'.

Reason for this plugin

In fact, I don't see so many usecases for this plugin.

Just other similar plugins are out of date, So providing one in case anyone needs it.
