Nuxt Layers

Shared foundation layers providing composables, models, repositories, and UI components across applications.

Layer Stack

layers.md - Complete layer architecture, what each provides, how to extend

Three-Layer Architecture

x-ui          → Extended UI components (XTable, XForm, XSlideover)
    ↓
nuxt-ui       → UI primitives (modals, toasts, tabs, overlays)
    ↓
base          → Core infrastructure (Model, Repository, composables, utils)

Extending Layers

// nuxt.config.ts
export default defineNuxtConfig({
  extends: [
    '../../../nuxt-layers/base',
    '../../../nuxt-layers/nuxt-ui',
    '../../../nuxt-layers/x-ui',
  ],
})

Importing from Layers

// Base layer imports
import Model from '#layers/base/app/models/Model'
import type { Castable, DataResponse } from '#layers/base/app/types'
import { BaseRepository } from '#layers/base/app/repositories/base-repository'
import { ModelHydrator } from '#layers/base/app/repositories/hydrators/model-hydrator'

// Composables auto-imported
const leadApi = useRepository('leads')
const { start, stop } = useWait()
const { can } = usePermissions()
