Building Your First Vue.js Components

This is where Claude Code truly shines. It understands Vue.js component patterns and can help you build everything from simple UI elements to complex interactive components.

Creating a Basic Component

Ask Claude Code: “Create a Vue.js component for a user profile card with props for name, email, and avatar”

Claude Code will generate:

<template>
  <div class="profile-card">
    <div class="avatar-container">
      <img 
        :src="avatar || defaultAvatar" 
        :alt="`${name}'s avatar`"
        class="avatar"
      >
    </div>
    <div class="profile-info">
      <h3 class="name">{{ name }}</h3>
      <p class="email">{{ email }}</p>
      <slot name="actions"></slot>
    </div>
  </div>
</template>

<script setup lang="ts">
interface Props {
  name: string
  email: string
  avatar?: string
}

const props = withDefaults(defineProps<Props>(), {
  avatar: ''
})

const defaultAvatar = '/src/assets/default-avatar.png'
</script>

<style scoped>
.profile-card {
  display: flex;
  gap: 1rem;
  padding: 1.5rem;
  border-radius: 0.5rem;
  box-shadow: 0 2px 8px rgba(0, 0, 0, 0.1);
  background: white;
}

.avatar {
  width: 60px;
  height: 60px;
  border-radius: 50%;
  object-fit: cover;
}

.profile-info {
  flex: 1;
}

.name {
  margin: 0 0 0.5rem 0;
  color: #2c3e50;
}

.email {
  margin: 0;
  color: #7f8c8d;
  font-size: 0.9rem;
}
</style>

Building Interactive Components

For more complex components, ask: “Create a Vue.js todo list component with add, remove, and toggle functionality using the Composition API”

<template>
  <div class="todo-app">
    <h2>My Todo List</h2>
    
    <form @submit.prevent="addTodo" class="add-todo-form">
      <input
        v-model="newTodoText"
        type="text"
        placeholder="Add a new todo..."
        class="todo-input"
        required
      >
      <button type="submit" class="add-button">Add</button>
    </form>

    <ul class="todo-list">
      <li
        v-for="todo in todos"
        :key="todo.id"
        class="todo-item"
        :class="{ completed: todo.completed }"
      >
        <input
          type="checkbox"
          :checked="todo.completed"
          @change="toggleTodo(todo.id)"
        >
        <span class="todo-text">{{ todo.text }}</span>
        <button @click="removeTodo(todo.id)" class="remove-button">×</button>
      </li>
    </ul>

    <div class="todo-stats">
      <p>{{ remainingTodos }} of {{ todos.length }} remaining</p>
    </div>
  </div>
</template>

<script setup lang="ts">
import { ref, computed } from 'vue'

interface Todo {
  id: number
  text: string
  completed: boolean
}

const newTodoText = ref('')
const todos = ref<Todo[]>([])
let nextId = 1

const remainingTodos = computed(() => 
  todos.value.filter(todo => !todo.completed).length
)

function addTodo() {
  if (newTodoText.value.trim()) {
    todos.value.push({
      id: nextId++,
      text: newTodoText.value.trim(),
      completed: false
    })
    newTodoText.value = ''
  }
}

function removeTodo(id: number) {
  const index = todos.value.findIndex(todo => todo.id === id)
  if (index > -1) {
    todos.value.splice(index, 1)
  }
}

function toggleTodo(id: number) {
  const todo = todos.value.find(todo => todo.id === id)
  if (todo) {
    todo.completed = !todo.completed
  }
}
</script>

<style scoped>
.todo-app {
  max-width: 400px;
  margin: 0 auto;
  padding: 2rem;
}

.add-todo-form {
  display: flex;
  gap: 0.5rem;
  margin-bottom: 1rem;
}

.todo-input {
  flex: 1;
  padding: 0.5rem;
  border: 1px solid #ddd;
  border-radius: 4px;
}

.add-button {
  padding: 0.5rem 1rem;
  background: #42b883;
  color: white;
  border: none;
  border-radius: 4px;
  cursor: pointer;
}

.todo-list {
  list-style: none;
  padding: 0;
}

.todo-item {
  display: flex;
  align-items: center;
  gap: 0.5rem;
  padding: 0.5rem;
  border-bottom: 1px solid #eee;
}

.todo-item.completed .todo-text {
  text-decoration: line-through;
  color: #999;
}

.todo-text {
  flex: 1;
}

.remove-button {
  background: #e74c3c;
  color: white;
  border: none;
  border-radius: 50%;
  width: 24px;
  height: 24px;
  cursor: pointer;
}

.todo-stats {
  margin-top: 1rem;
  text-align: center;
  color: #666;
}
</style>

Advanced Component Patterns

Claude Code can help you implement advanced Vue.js patterns:

  • Suspense: Async component loading

Project Structure Best Practices

Claude Code can help you organize your Vue.js project for maximum maintainability and scalability.

Recommended Project Structure

Ask: “Create a scalable Vue.js project structure with TypeScript”

src/
├── assets/
│   ├── images/
│   └── styles/
├── components/
│   ├── common/
│   ├── forms/
│   └── layout/
├── composables/
├── router/
├── stores/
├── types/
├── utils/
├── views/
├── App.vue
└── main.ts

Setting Up Routing

// router/index.ts
import { createRouter, createWebHistory } from 'vue-router'
import type { RouteRecordRaw } from 'vue-router'

const routes: RouteRecordRaw[] = [
  {
    path: '/',
    name: 'Home',
    component: () => import('@/views/HomeView.vue')
  },
  {
    path: '/about',
    name: 'About',
    component: () => import('@/views/AboutView.vue')
  }
]

export default createRouter({
  history: createWebHistory(),
  routes
})

State Management with Pinia

// stores/user.ts
import { defineStore } from 'pinia'
import { ref, computed } from 'vue'

export const useUserStore = defineStore('user', () => {
  const user = ref(null)
  const isAuthenticated = computed(() => user.value !== null)

  function login(userData: any) {
    user.value = userData
  }

  function logout() {
    user.value = null
  }

  return { user, isAuthenticated, login, logout }
})
