    Expose Loader

    The expose loader adds modules to the global object. This is useful for debugging, or supporting libraries that depend on libraries in globals.

    Install

    npm i expose-loader --save

    Usage

    Note: Modules must be require()'d within in your bundle, or they will not be exposed.

    require("expose-loader?libraryName!./file.js");
    // Exposes the exports for file.js to the global context on property "libraryName".
    // In web browsers, window.libraryName is then available.

    For example, let's say you want to expose jQuery as a global called $:

    require("expose-loader?$!jquery");

    Thus, window.$ is then available in the browser console.

    Alternately, you can set this in your config file:

    webpack v1 usage

    module: {
      loaders: [
        { test: require.resolve("jquery"), loader: "expose-loader?$" }
      ]
    }

    webpack v2 usage

    module: {
      rules: [{
              test: require.resolve('jquery'),
              use: [{
                  loader: 'expose-loader',
                  options: '$'
              }]
          }]
    }

    Let's say you also want to expose it as window.jQuery in addition to window.$. For multiple expose you can use ! in loader string:

    webpack v1 usage

    module: {
      loaders: [
        { test: require.resolve("jquery"), loader: "expose-loader?$!expose-loader?jQuery" },
      ]
    }

    webpack v2 usage

    module: {
      rules: [{
              test: require.resolve('jquery'),
              use: [{
                  loader: 'expose-loader',
                  options: 'jQuery'
              },{
                  loader: 'expose-loader',
                  options: '$'
              }]
          }]
    }

    The require.resolve is a Node.js call (unrelated to require.resolve in webpack processing). require.resolve gives you the absolute path to the module ("/.../app/node_modules/react/react.js"). So the expose only applies to the react module. And it's only exposed when used in the bundle.
