Do you have experience participating in migration from Vue 2 to Vue 3 — what exactly did you do yourself?

During the migration from Vue 2 to Vue 3, I was involved in the following tasks:

• Analyzing existing code for deprecated API usage and syntax incompatible with Vue 3.
• Rewriting components using the Composition API where appropriate to improve readability and support.
• Updating dependencies and plugins, checking their compatibility with Vue 3.
• Configuring the build system (e.g., with Vite or updating Webpack configuration) to support new Vue 3 features.
• Testing the application, fixing bugs related to changes in reactivity and component lifecycle.

Example of replacing Options API with Composition API:

// Vue 2
export default {
  data() {
    return { count: 0 };
  },
  methods: {
    increment() {
      this.count++;
    }
  }
}

// Vue 3
import { ref } from 'vue';
export default {
  setup() {
    const count = ref(0);
    function increment() {
      count.value++;
    }
    return { count, increment };
  }
}
