Warning in Vue 3: Production is being disrupted by "tags with side effects"

After recently upgrading from Vue 2 to Vue 3, I encountered a problem in my app where certain parts show a warning in development mode:

[Vue warn]: Template compilation error: Tags with side effect (<script> and <style>) are ignored in client component templates.

In Vue 2, these warnings were hidden in production. However, in Vue 3, encountering these warnings results in the entire page breaking and showing a blank screen. Surprisingly, they work fine in development.

Removing all of these <script> tags is not a feasible solution for me since they are dynamically inserted by my CMS (Shopify).

Is there a way to handle these errors in production so that they do not disrupt the functioning of my site?

Answer №1

This solution has proven to be the most effective for me thus far.

Substitute:

<script>
  // Insert JavaScript code here
</script>

With:

<component :is="'script'">
  // Add JavaScript here
</component>

Nonetheless, I am seeking a universal setting so that I do not have to manually apply this change for each plugin. At present, my application seems quite fragile in the event that a team member adds another CMS plugin.

I want to prevent the application from crashing upon encountering a <script> tag...

In my situation, I successfully resolved the issue by relocating the id="app" attribute from <body> to the first <div>.

Previous code snippet:

<body id="app">
  <div>
    ...
  </div>
</body>

Updated code snippet:

<body>
   <div id="app">
     ...
   </div>
</body>

My experience may be a bit delayed, but I encountered a similar issue and managed to find a solution that worked for me.

The key is to make sure you embed the script right before the closing body tag in your index.html file. It seems like having it within the main div can cause issues.

To clarify, your setup should resemble the following:

<body>
  <div id="app">
    
  </div>
  <script src="./main.js"></script>
</body>

After trying suggested solutions in my app without success, I discovered that the warning disappeared when I realized that a Vue app component must have a non-empty template. This revelation came from observing another working app.

createApp({ }).mount(somewhere);  // warning
createApp({ template: `` }).mount(somewhere);  // warning
createApp({ template: `4` }).mount(somewhere);  // goes away

My "app" consisted of a single HTML file with subsequent script elements.
