[SOLVED] import.meta undefined in components (Vite/Vue3)

import.meta undefined in components (Vite/Vue3)

i am trying to access the import.meta.env Variable 'APP_SOCKET_URL' in my component but it says Uncaught TypeError: import_meta.env is undefined

In my main.js file import.meta.env works fine. In all other files it doesnt work and I dont know why. Maybe someone can help me there.

Here is the code of my data function:

 data(){


  const socket = new Socket(import.meta.env.APP_SOCKET_URL || `ws://${location.href}/ws`);
  return {
     socket
  };
}

In my .env file I added:

APP_SOCKET_URL="ws://localhost:8765"

And in my vite.config I changed the envPreix to "APP_"

Here is my Setup:

Vite Version 3.1.4
Vue 3 Version 3.2.40 Programming in Typescript Thanks and have a nice day!

EDIT:

I found the error. If I change the script lag from 'ts' to 'js' it works. So the problem is with typescript, but I dont know how to fix that.

Solution

Your answer should lie here in this documentation

Vite generates the types for you if configurated correctly in the tsconfig.json.
