nuxt-config-schema v0.4.6

Nuxt Config Schema

This is a proof of concept module for a feature in Nuxt 3 that automatically infers and generates schema based on user provided configuration from several sources using unjs/untyped and supports extending layers.

Schema can be defined in nuxt.schema.ts or $schema field in nuxt.config.ts.

Read the proposal for Nuxt 3

This experiment is landed to Nuxt 3 core since 3.1.0 (https://github.com/nuxt/nuxt/pull/18410)

Usage

1. Install nuxt-config-schema as dev dependency:

# npm
npm i -D nuxt-config-schema

# pnpm
pnpm add -D nuxt-config-schema

# yarn
yarn add nuxt-config-schema

2. Add module to nuxt.config:

export default defineNuxtConfig({
  modules: ['nuxt-config-schema'],
})

3. Create nuxt.schema.ts:

export default defineNuxtConfigSchema({
  appConfig: {
    test2: {
      $default: 'from nuxt.schema',
    },
  },
  /** Config schema for another integration */
  anotherConfig: {
    aTest: '123',
  },
})

4. Use nuxi dev or nuxi build commands

You can access generated schema (json, markdown and types) from .nuxt/schema/ directory and also hooks below:

• schema:extend(schemaDefs): Extend schema defenitions (first call after modules:done hook)
• schema:resolved(schema): Extend resolved schema after merging (first call after modules:done hook)
• schema:beforeWrite(schema): Extend resolved schema just before writing to filesystem (called after build:done hook)
• schema:written: Hook will be called when schema has been written and updated to filesystem

Development

• Run npm run dev:prepare to generate type stubs.
• Use npm run dev to start playground in development mode.
