Transitioning from Vue 2 to Vue 3

Migrating to Vue 3 is straightforward. Here’s a quick migration guide:

Step 1: Install Vue 3

Install Vue 3 in your project:

npm install vue@next

Step 2: Update Dependencies

Ensure that your Vue-related dependencies are compatible with Vue 3. Check for updated versions of libraries and plugins.

Step 3: Adapt Your Code

Replace Options API with Composition API (optional):

While the Options API is still supported, transitioning to the Composition API can make your code more maintainable.

// 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);
    const increment = () => count.value++;
    return { count, increment };
  },
};
