After migrating our vue.js 2.x project to typescript, I came across Evan You's comment in this issue:
https://github.com/vuejs/rfcs/pull/17#issuecomment-494242121
The Class API proposal has been dropped, so I switched to the regular option-based version of vue.js, which presented me with a lot of type problems.
I am wondering if vue.js 2.x composition api is fully compatible with typescript and should I use it to solve all these issues? What would be the best practice in this situation?
I'm not entirely clear on what it means for something to be "fully compatible with TypeScript." However, I can confirm that TypeScript works seamlessly with the Vue composition API, enhancing both code quality and developer experience.
If you're interested, here's a sample snippet showcasing the composition plugin in action with Vue 2:
import { computed, createComponent, reactive } from "@vue/composition-api";
export default createComponent({
name: "Hello",
template: `<p>{{ state.message }}</p>`,
props: {
name: {
type: String,
required: true
}
},
setup(props, context) {
const state = reactive({
message: computed(() => `Hello, ${props.name}!`)
});
return {
state
};
}
});
All of the above code is fully typed. The composition API elements (such as createComponent, reactive, computed) come with accurate type support. It's worth noting that thanks to the composition API, usage of this becomes unnecessary.
Absolutely, Vue.js seamlessly integrates with TypeScript thanks to the built-in TypeScript tooling support provided by Vue CLI. Simply install it using npm or yarn, as explained here. This means you won't need any extra tools to start using TS with Vue. The links also provide insight into recommended setup and fundamental usage.
