Terminal not showing errors when running in dev mode. No error checking in code either

[philippilievski]

Describe the bug

When working on a vue project created using vite:
Whenever i save a file with an error the error doesn't immediately show in console. Only upon refreshing the browser page it shows.

In the Vue language-tools somebody told me to move this here:

Reproduction

Steps to reproduce

1. Open terminal and create a new project:
   npm create vue@latest
2. Add Typescript when asked for it
3. Run npm install in project directory
4. Start dev server by running: npm run dev
5. Purposefully generate error in code in my example i typed into Homeview.vue and save the file:

<script setup lang="ts">
import TheWelcome from '../components/TheWelcome.vue'
this is an error generated on purpose ; = ";";
</script>

6.Now the console should not show any error

7. Upon opening the application in the browser the error gets displayed (only in browser)
8. Only upon page refresh the terminal now also displays the error

This is part of the philosophy of Vite core to be light. You can look for plugin to add TS errors to the console, I've made https://www.npmjs.com/package/vite-plugin-tsc-watch for myself, but https://www.npmjs.com/package/vite-plugin-checker?activeTab=readme is way more popular
