Can a Vue.js application be inserted within the custom code block on a Webflow page? Has anyone successfully done this yet?

You can embed a Vue.js application inside a Webflow page using the Custom Code Embed or the Page Settings > Custom Code fields. Yes, others have successfully done this, but it comes with important limitations and requirements.

1. Where You Can Embed Vue.js

• Use the Embed element in the Webflow Designer to place Vue.js inside a specific section of a page.
• Alternatively, place the Vue.js script tags inside the Custom Code section of your page settings — specifically in the Before area for correct script execution.

2. Key Requirements for Success

• Include Vue.js from a CDN (e.g., https://cdn.jsdelivr.net/npm/vue@2 or Vue 3).
• Create a unique container element in HTML (like <div id="app"></div>) in the Embed element.
• Initialize Vue only once Webflow loads (to avoid issues from Webflow’s page rendering lifecycle).

3. Common Challenges Faced

• Webflow manages the DOM, so Vue apps should be scoped in their own element and mounted only after the DOM is ready.
• Interactions or animations built in Webflow can interfere with Vue rendering if both affect the same nodes.
• SSR or advanced Vue plugins can't be fully used — this is strictly a small client-side Vue SPA approach.

4. Example of Success Cases

• Developers have integrated Vue components (like calculators, single-page widgets, or forms) into Webflow.
• They typically keep the Vue logic modular and host shared resources (like component templates or external APIs) outside Webflow when needed.

Summary

Yes, you can embed a Vue.js application in Webflow using the Embed element or Custom Code areas. Many users have done so successfully for self-contained Vue components. Proper scoping and DOM management are essential to avoid conflicts with Webflow’s native rendering.
