What steps should I take to update my Vue 2 components for use in Vue 3?

I am considering using my Vue 2 components in a new Vue 3 project, is this possible? For example, I currently have Vue 2 components for "FAQ" and "About Us". Can I incorporate these components into a Vue 3 project by creating routes to use them? I initially tried using migration build tools, but encountered numerous errors that I couldn't fix, so now I am looking to rewrite them. What steps should I take to achieve this transition?

Example in Vue 2:

/src/components/faq
/src/components/about-us

In Vue 3:

// in route.js
import {FAQ, AboutUS} from "my-component-vue2";

export default Routes [{
  path: "/faq",
  component: () => FAQ
}]

Answer №1

One possible approach is to utilize webpack federated modules to share components, allowing you to run microfrontends with Vue2 components in one module and Vue3 components in another. You could also consider simply copying all the Vue2 components into the Vue3 project to test compatibility before creating new Vue3 components. Have you experimented with this method yet?
