Struggling with TypeScript compilation in a Vue.js project? Encounter error code TS2352

Here is my code snippet from window.ts

import Vue from 'vue'

interface BrowserWindow extends Window {
  app: Vue
}

const browserWindow = window as BrowserWindow
export default browserWindow

Encountering a compilation error

Error message: TS2352 - The conversion of type 'Window & typeof globalThis' to 'BrowserWindow' 
             appears to be problematic due to insufficient overlap between the two types. Consider 
             converting the expression to 'unknown' first.
  Property 'app' is missing in type 'Window & typeof globalThis' but required in type 'BrowserWindow'.

Answer №1

To resolve the error message, simply convert your windows variable to type unknown before casting it as a BrowserWindow:

const browserWindow = window as unknown as BrowserWindow
