volar-component-types v1.0.0

volar-component-types

A module that provides Volar types for auto-discovered components in Nuxt 2.

Introduction

Nuxt 2, like Nuxt 3, auto-discovers components but unlike Nuxt 3, it doesn't automatically generate types for those components so Vue Language Tools (formerly Volar) is not able to type-check those unless they are explicitly imported (which defeats the purpose of auto-discovering). This module takes care of registering types for all auto-discovered components so that Volar is aware of those and can type-check them. Instead of generating a plain type definition file, it uses an experimental Volar feature (experimentalAdditionalLanguageModules) for that so that "Go to definition" in also supported properly in the editor (not even Nuxt 3 supports that).

Setup

1. Install volar-component-types package:

   # Npm
   npm i -D volar-component-types
   # Yarn
   yarn add -D volar-component-types

2. Add the module to buildModules in nuxt.config.js.

   export default {
       buildModules: [
          'volar-component-types/nuxt',
       ],
   }

3. Set following options in tsconfig.json:

   {
      // other options...
      "vueCompilerOptions": {
        "target": 2.7,
        "strictTemplates": true,
        "experimentalAdditionalLanguageModules": ["volar-component-types"],
      }
   }

4. Extend types array in tsconfing.json to augment Nuxt Config with module configuration types.

   {
      "compilerOptions": {
         "types": [
            "volar-component-types/nuxt",
         ]
      }
   }

5. Run nuxt dev.

Note This module generates a ./.nuxt/components/volar-component-data.json file relative to the tsconfig.json and the Volar Language Module expects to find it there. The location of the generated file is currently not configurable.
