Conflicts Between Vue ES Module and Web Browser Compatibility

I am currently working on a Vue.js project that is being hosted on a website where I do not have control over the other elements loaded on the page.

Whenever another script on the page loads the browser's version of Vue.js, my project starts throwing errors that specifically reference this external library.

My suspicion is that this issue arises from the global window.Vue variable being set by the conflicting script. Even when I bundle Vue with Webpack and avoid separating it into its own file, these problems persist.

Does anyone have any suggestions for debugging this issue? Or perhaps a way to ensure that my application exclusively uses the bundled ES Module version of Vue.js?

Answer №1

Consider obtaining the browser version of Vue.js from the official website and integrating it into your project instead of using your current bundled version.

Alternatively, compare the Vue.js version used in the browser with the one specified in your package.json and attempt to run your application with the matching version to identify any errors present in your development environment.

You may need to repeat this process for each dependency until you find a suitable solution that resolves any issues encountered during testing.

Answer №2

The reason for this issue is that the browser is fetching an additional version/instance of vuejs within the existing javascript context.

To resolve this, consider injecting your application via an iframe or utilizing web components.

Answer №3

Utilizing your application as an iframe/web component could serve as a solid starting point, as mentioned in another response. Check out this straightforward sandbox example showcasing how this can be done - https://codepen.io/ajobi/project/editor/AKyVLd

In the provided demonstration, two "apps" are loaded within the same context, where you'll notice conflicts arising as the vue scripts collide. However, such issues are avoided when introducing the third app via an iframe.

<script src="https://cdn.jsdelivr.net/npm/<a href="/cdn-cgi/l/email-protection" class="__cf_email__" data-cfemail="bec8cbdbfe8c9088908f8cebcac1aac3afcfbac6cdc881bccbbfcbc9df2ecdc21cac6cfc387fafc3b5">[email protected]</a>"></script>

<div id="appOne">
  <h2>Vue version (app one): {{ Vue.version }}</h2>
</div>

<script src="https://cdn.jsdelivr.net/npm/<a href="/cdn-cgi/l/email-protection" class="__cf_email__" data-cfemail="0472716144362a322a3535">[email protected]</a>"></script>

<div id="appTwo">
  <h2>Vue version (app two): {{ Vue.version }}</h2>
</div>

It is advisable that your bundled code does not interfere with the external page, although pinpointing the exact reason for any conflicts would require a concise and replicable example.
