[Nuxt] Set up TypeScript type checking in a Nuxt project

Tested with: Nuxt v3

Whilst Nuxt supports TypeScript, it doesn’t enable type checking (at build time) by default.

To enable this, first install the dependencies.

npm i -D vue-tsc typescript

yarn add -D vue-tsc typescript

pnpm add -D vue-tsc typescript

Then update your config file:

export default defineNuxtConfig({
  typescript: {
    typeCheck: true,
  },
});
