Nuxt 3 ignores TypeScript errors when saving the code

Question

I have a problem. When there is a TypeScript error in the code, there is an error in the IDE, but I anyways can save it and run in the browser. Is it okay?

Here is the code:

<script lang="ts" setup>
const a = ref<string>(5);
</script>

I tried export default and export default defineComponent(), but it didn't help.

Here is the screenshoot of my IDE

As stated on the nuxt 3 documentation typescript/type-checking:

By default, Nuxt doesn't check types when you run nuxi dev or nuxi build, for performance reasons.

If you want to enable it, you need to:

• install vue-tsc and typescript as devDependencies
• add this in your nuxt.config.js:

typescript: {
  typeCheck: true,
}
