expose-loader fails to reveal changes made to the object being exposed

Currently, I am using Webpack 2, Bootstrap 3, and TypeScript in my project. My goal is to integrate npm and packaged bundles into an existing application seamlessly. To achieve this, I have utilized the ProvidePlugin to ensure jQuery is accessible and the expose-loader to expose jQuery to external dependencies.

Initially, I faced challenges with configurations involving

(<any> global).$ = global.jQuery = $;
or webpack module: { rules [{}] }, however, I managed to find success with the following setup:

plugins: ([
    // allow usage of jquery outside webpack modules
    new webpack.ProvidePlugin({
        $: "jquery",
        jQuery: "jquery",
        jquery: "jquery",
        "window.jQuery": "jquery",
        "window.$": "jquery"
    }),
]),

In my entry file, entry.ts:

import "expose-loader?$!jquery"
import "expose-loader?jQuery!jquery"

Despite setting up everything correctly, when attempting to use import "bootstrap", I encountered issues where $(...).popover() worked within my module, but $(...).popover resulted in an error outside the module:

Uncaught TypeError: $(...).popover is not a function

I am seeking advice on how to make jQuery methods, such as the bootstrap popover method, available globally outside of my modules?

Answer №1

After some investigation, PluginProvider was providing a conflicting version of jQuery to the application compared to what expose-loader was supplying. This caused Bootstrap to initialize with PluginProvider's jQuery, while a different instance of jQuery was accessible through the window.

To resolve this issue, removing PluginProvider and exclusively using the expose-loader is recommended. Additionally, import jQuery manually where needed as a result of eliminating PluginProvider.
