Vue 3 + Vite + Typescript - dev & build not picking up TS Errors

Question

I'm using Vue 3, Vite and TypeScript. I wanted to give a try of building Vue project with TypeScript. The configuration has been really difficult so far. I've been looking at various documentations but I'm struggling to achieve my goal. The project shouldn't build and throw errors if there's something wrong with the code.

I'm attaching the code below and I'd like to ask for help, please.

App.vue

<template>
  <header>
    <h1>The Learning Resources App</h1>
  </header>
</template>

<script lang="ts">
import { defineComponent } from 'vue';

// import StoredResource from '//StoredResource';

interface VueData {
  storedResources: StoredResource[];
}

export default defineComponent({
  name: 'App',
  data(): VueData {
    return {
      storedResources: [
        {
          id: 'official-guide' as number,
          title: 'Official Guide',
          description: 'The official Vue.js documentation.',
          link: 'https://vuejs.org/',
        },
        {
          id: 'google',
          title: 'Google',
          description: 'Learn to google...',
          link: 'https://www.google.co.uk/',
        },
      ],
    };
  },
});
</script>

For any other developers with this question. You can use vite-plugin-checker for this case.

Install plugin

npm install --save-dev vite-plugin-checker
# or
yarn add -D vite-plugin-checker

In your vite.config.ts

import checker from 'vite-plugin-checker';

export default defineConfig({
  plugins: [
    // your plugins
    checker({
      typescript: true,
    }),
  ],
  // your config
})
