Maz-UI v4 - Vue & Nuxt Component Library

Maz-UI is a comprehensive, standalone component library for Vue 3 and Nuxt 3 applications, offering 50+ production-ready components, powerful theming, internationalization, and exceptional developer experience.

Latest Version: 4.3.3 (as of 2025-12-29) Package: maz-ui | @maz-ui/nuxt | @maz-ui/themes | @maz-ui/translations | @maz-ui/icons

Quick Start

Vue 3 Installation

# Install core packages
pnpm add maz-ui @maz-ui/themes

# Or with npm
npm install maz-ui @maz-ui/themes

Setup in main.ts:

import { createApp } from 'vue'
import { MazUi } from 'maz-ui/plugins/maz-ui'
import { mazUi } from '@maz-ui/themes'
import { en } from '@maz-ui/translations'
import 'maz-ui/styles'
import App from './App.vue'

const app = createApp(App)

app.use(MazUi, {
  theme: { preset: mazUi },
  translations: { messages: { en } }
})

app.mount('#app')

Use Components:

<script setup>
import MazBtn from 'maz-ui/components/MazBtn'
import MazInput from 'maz-ui/components/MazInput'
import { ref } from 'vue'

const inputValue = ref('')
</script>

<template>
  <MazInput v-model="inputValue" label="Name" />
  <MazBtn color="primary">Submit</MazBtn>
</template>

Nuxt 3 Installation

# Install Nuxt module
pnpm add @maz-ui/nuxt

Setup in nuxt.config.ts:

export default defineNuxtConfig({
  modules: ['@maz-ui/nuxt']
  // That's it! Auto-imports enabled 🎉
})

Use Components (no imports needed):

<script setup>
// Auto-imported composables
const theme = useTheme()

Template Structure

Maz-UI provides two sets of production-ready templates organized by framework:

Vue 3 + Vite Templates (templates/vue/)

• ✅ Pure Vue 3 with Vite
• ✅ Uses standard fetch() API
• ✅ Explicit imports for all dependencies
• ✅ No framework-specific dependencies
• ✅ Optimized for SPA development

Use when: Building Vue 3 applications with Vite

Available templates:

• setup/vite.config.ts - Vite configuration with auto-imports
• components/form-basic.vue - Basic form validation
• components/form-multi-step.vue - Multi-step form with stepper
• components/dialog-confirm.vue - Dialog confirmation patterns
• components/data-table.vue - Data table with pagination, search, sort

Nuxt 3 Templates (templates/nuxt/)

• ✅ Nuxt 3 optimized
• ✅ Uses $fetch (Nuxt's ofetch wrapper)
• ✅ Leverages auto-imports for components and composables
• ✅ Showcases SSR patterns and server routes
• ✅ Optimized for full-stack Nuxt development

Use when: Building Nuxt 3 applications

Available templates:

• setup/nuxt.config.ts - Nuxt configuration with Maz-UI module
• components/form-basic.vue - Basic form validation (auto-imports)
• components/form-multi-step.vue - Multi-step form (auto-imports)
• components/dialog-confirm.vue - Dialog patterns (auto-imports)
• components/data-table.vue - Data table with reactive data loading

Both template sets:

• ✅ Fix all validation, type inference, and pagination issues
• ✅ Follow framework best practices
• ✅ Are production-ready and fully tested
• ✅ Include setup configs and component examples

Top 6 Common Errors

1. Missing Theme Plugin Error

Error: "useTheme must be used within MazUi plugin installation" Cause: MazUi plugin not installed or theme composable disabled Fix:

// Vue
app.use(MazUi, { theme: { preset: mazUi } })

// Nuxt
export default defineNuxtConfig({
  mazUi: {
    composables: { useTheme: true },
    theme: { preset: 'maz-ui' }
  }
})

2. Auto-Import Not Working (Nuxt)

Error: Components/composables not found despite Nuxt module installed Cause: Module not properly configured or cache issue Fix:

# Clear Nuxt cache
rm -rf .nuxt node_modules/.cache
pnpm install

Verify nuxt.config.ts:

export default defineNuxtConfig({
  modules: ['@maz-ui/nuxt']
})

3. Styles Not Applied

Error: Components render but have no styling Cause: CSS not imported Fix Vue:

import 'maz-ui/styles' // Add this line

Fix Nuxt:

export default defineNuxtConfig({
  mazUi: {
    css: { injectMainCss: true } // Ensure this is true
  }
})

4. TypeScript Errors with Components

Error: Cannot find module 'maz-ui/components/MazBtn' Cause: Missing type definitions or incorrect import path Fix:

// Correct import
import MazBtn from 'maz-ui/components/MazBtn'

// Or with auto-import (Nuxt)
// No import needed, just use <MazBtn>

Ensure tsconfig.json includes:

{
  "compilerOptions": {
    "types": ["maz-ui/types"]
  }
}

5. Phone Input Country Detection Fails

Error: MazInputPhoneNumber doesn't detect country or shows wrong flag Cause: Missing libphonenumber-js dependency or country data not loaded Fix:

# Install peer dependency
pnpm add libphonenumber-js

<MazInputPhoneNumber
  v-model="phone"
  default-country-code="US"
  preferred-countries="['US', 'CA', 'GB']"
/>

6. Translations Not Loading or Showing Raw Keys

Error: Translation keys showing as raw strings like inputPhoneNumber.phoneInput.example instead of translated text Causes:

• Missing locale import
• Lazy loading not awaited properly
• Language file failed to load asynchronously
• Missing preloadFallback configuration
• SSR hydration mismatch (Nuxt)

Fix Vue (Immediate Loading):

import { fr } from '@maz-ui/translations'

app.use(MazUi, {
  translations: {
    locale: 'fr',
    fallbackLocale: 'en',
    preloadFallback: true,
    messages: { fr } // Import immediately
  }
})

Fix Vue (Lazy Loading):

app.use(MazUi, {
  translations: {
    locale: 'fr',
    preloadFallback: true, // Ensure fallback is preloaded
    messages: {
      fr: () => import('@maz-ui/translations/locales/fr')
    }
  }
})

// In component: ALWAYS use await
const { setLocale } = useTranslations()
await setLocale('fr') // Don't forget await!

Fix Nuxt (Avoid Hydration):

import { fr } from '@maz-ui/translations'

export default defineNuxtConfig({
  mazUi: {
    translations: {
      locale: 'fr',
      preloadFallback: true,
      messages: {
        // CRITICAL: Provide initial locale immediately (not as function)
        fr, // SSR requires immediate load

        // Other languages can be lazy
        es: () => import('@maz-ui/translations/locales/es')
      }
    }
  }
})

Error Handling:

<script setup>
const { setLocale } = useTranslations()
const toast = useToast()

async function switchLanguage(locale) {
  try {
    await setLocale(locale)
    toast.success(`Language changed to ${locale}`)
  } catch (error) {
    console.error('Translation loading error:', error)
    toast.error('Failed to load translations')
  }
}
</script>

Tree-Shaking Best Practices

Direct Imports (Most Optimized):

// ✅✅✅ Best - smallest bundle
import MazBtn from 'maz-ui/components/MazBtn'
import { useToast } from 'maz-ui/composables/useToast'
import { vClickOutside } from 'maz-ui/directives/vClickOutside'

Index Imports (Good):

// ✅ Good - tree-shakable
import { MazBtn, MazInput } from 'maz-ui/components'
import { useToast, useTheme } from 'maz-ui/composables'

Avoid (Not Tree-Shakable):

// ❌ Imports everything
import * as MazUI from 'maz-ui'

Advanced Topics

Performance Optimization

Maz-UI can be optimized from ~300KB to ~15KB through strategic imports and tree-shaking. Use auto-import resolvers (MazComponentsResolver, MazDirectivesResolver, MazModulesResolver) for optimal bundle size, lazy load components with dynamic imports, and split code by feature. Load performance.md for comprehensive bundle optimization strategies.

SSR & SSG

Full server-side rendering and static site generation support with three theme strategies: hybrid (critical CSS injection, no FOUC), buildtime (smallest bundle, static themes), and runtime (full theme switching, larger bundle). Prevent hydration mismatches by wrapping client-only components in <ClientOnly>. Load ssr-ssg.md for critical CSS patterns, dark mode without flash, and SSR/SSG checklist.

Accessibility

All Maz-UI components are WCAG 2.1 AA compliant with proper ARIA attributes, keyboard navigation, focus management, and screen reader support. Components include semantic HTML, color contrast ratios >4.5:1, and accessible form validation. Load accessibility.md for keyboard shortcuts, focus trap patterns, and accessibility testing checklist.

Form Validation

The useFormValidator() composable integrates with Valibot for type-safe schema validation with full TypeScript inference. Supports 5 validation modes (lazy, aggressive, eager, blur, progressive), async validation, custom validators, and real-time error messages. Load form-validation.md for comprehensive validation patterns and real-world examples.

Auto-Import Resolvers

Critical for tree-shaking: Use unplugin-vue-components and unplugin-auto-import with Maz-UI resolvers to import only what you use. Reduces bundle size by 60-90% compared to global imports. Configure prefix handling to avoid naming conflicts with other libraries. Load resolvers.md for complete resolver configuration and troubleshooting.
