This article is about how to make variables created outside of Vue responsive. The editor thinks it is very practical, so share it with you as a reference and follow the editor to have a look.

If you get a variable from outside of Vue, it's nice to be able to make it responsive. This way you can use it in computational props, observers, and anywhere else, and it works just like any other state in Vue.

When you are using options API, you just need to put it in the section of the data component:

Const externalVariable = getValue (); export default {data () {return {reactiveVariable: externalVariable,};}}

When you use combined API in Vue 3, you can use ref or reactive like this:

Import {ref} from 'vue';// can complete const externalVariable = getValue (); const reactiveVariable = ref (externalVariable); / / access console.log (reactiveVariable.value) using .value; use reactive instead:\ import {reactive} from' vue';// can complete const externalVariable = getValue () completely outside Vue components; / / Reactive is only applicable to objects and arrays const anotherReactiveVariable = reactive (externalVariable); / / access console.log (anotherReactiveVariable) directly

If you are still using Vue 2 (like many of us), you can use observable instead of reactive to get exactly the same results.
