Currently, our project is utilizing Vue 2.x and our components are structured as follows:
@Component({
template: `
<div>
some code ....
<div> `
})
export default class class1 extends Vue {
@Prop() data: IsomeData;
}
Vue-class-component and vue-property-decorator allow us to write code in this manner. According to the documentation, @Component has been replaced with @Options({}).
What is the best way to transition to Vue3 without having to undergo major refactoring?
Give this a shot.
<template>
<div>
more code here ...
<div>
</template>
<script>
import { Vue } from "vue-class-component";
import { Prop } from "vue-property-decorator";
export default class Home extends Vue {
@Prop() info: IinfoData;
}
</script>
If you're coming across this post in the year 2025, please be aware that in Vue3, it's no longer advisable to utilize the class-component approach. The developers behind the package have ceased its maintenance for versions past Vue2.
The aforementioned library is now considered outdated and is no longer receiving updates. It is strongly advised not to use Class-based components with Vue 3. Instead, it is recommended to employ Single-File Components, Composition API, and other modern techniques when working on large-scale applications. If you still prefer using classes, you may want to explore the alternative community-backed project vue-facing-decorator.
In the year 2023, my goal is to transition from Vue2 to Vue3. I came across which had some useful information.
Moreover, if you are considering moving away from class components, the CLI tool vue-class-migrator could be beneficial during the migration process.
The vue-class-migrator appears to be a promising solution for the upgrade.
