Access the plugin object from a Vue.js 2 component using typescript

Question

Access the plugin object from a Vue.js 2 component using typescript

I devised a plugin object to handle the regular expressions used in my application in a more global manner. Here's an example of how it looks:

import Vue from "vue";

Vue.prototype.$regex = { 
  //isEmail function implementation goes here
}

This piece of code functions well in JavaScript. However, when I tried implementing it in my new TypeScript project like so:

methods: {
  isEmail(string: string): boolean {
    return this.$regex.isEmail(string)
  }
}

I encountered the following error message:

Property '$regex' does not exist on type 'CombinedVueInstance<Vue...

Can anyone advise on the proper method for utilizing my plugin in a Vue.js 2 project with TypeScript?

typescript vue.js vuejs2

Answer №1

It seems that the error is occurring because TypeScript is not aware of the $regex in Vue's object prototype.

To resolve this issue, you can create a file to be included by TypeScript, such as types.d.ts in the src directory, and define the type for $regex like so:

import Vue from "vue";

declare module 'vue/types/vue' {
  export interface Vue {
    $regex: { isEmail: (some: string) => bool }
  }
}
