Typescript Vue Plugin

I am currently working on developing a Vue logger plugin

export default new (class CustomLogger {
  public install(Vue: any) {
    Vue.prototype.$log = this;
  }

  error(text: string) {
      console.log(text)
  }
})();

This code is located in main.ts file

import customLogger from "./plugins/logger";
Vue.use(customLogger);

However, I am facing an issue where I cannot reference this.$log in components - why?

For example, in Login.vue file:

this.$log.error("bla");

The error message reads:

Property $log does not exist on type Login

typescript vue.js

To enhance the type definitions for Vue plugins, you will need to update the .d.ts file by adding the type definition for $log:

// src/my-log-plugin.d.ts
import Vue from 'vue'

declare module 'vue/types/vue' {
  interface Vue {
    $log: {
      error: (message: string) => void
    }
  }
}

export {}
