- Redis
- GraphQL/REST/tRPC

Infrastructure:
- Docker
- Kubernetes (basics)
- AWS/GCP/Azure
- Vercel/Netlify/Railway
- GitHub Actions

// Essential concepts
const fundamentals = [
  'Closures and scope',
  'Async/await and Promises',
  'Event loop',
  'ES6+ features',
  'TypeScript types',
  'Generics',
]

/* Modern CSS features */
.container {
  display: grid;
  gap: 1rem;
  container-type: inline-size;
}

@container (min-width: 600px) {
  .item {
    grid-column: span 2;
  }
}

<script setup lang="ts">
// Nuxt 4 component
interface Props {
  title: string
  items: Array<{ id: string; name: string }>
}

const props = defineProps<Props>()
const emit = defineEmits<{
  select: [itemId: string]
}>()
</script>

<template>
  <div>
    <h2>{{ title }}</h2>
    <ul>
      <li
        v-for="item in items"
        :key="item.id"
        @click="emit('select', item.id)"
      >
        {{ item.name }}
      </li>
    </ul>
  </div>
</template>

// Zustand example
import { create } from 'zustand'

interface Store {
  items: Item[]
  addItem: (item: Item) => void
  removeItem: (id: string) => void
}

export const useStore = create<Store>((set) => ({
  items: [],
  addItem: (item) => set((state) => ({
    items: [...state.items, item]
  })),
  removeItem: (id) => set((state) => ({
    items: state.items.filter(i => i.id !== id)
  })),
}))

// Hono API example
import { Hono } from 'hono'
import { z } from 'zod'

const app = new Hono()

const userSchema = z.object({
  name: z.string().min(1),
  email: z.string().email(),
})

app.get('/api/users', async (c) => {
  const users = await db.user.findMany()
  return c.json({ data: users })
})

app.post('/api/users', async (c) => {
  const body = await c.req.json()
  const data = userSchema.parse(body)
  const user = await db.user.create({ data })
  return c.json({ data: user }, 201)
})

-- PostgreSQL schema
CREATE TABLE users (
  id UUID PRIMARY KEY DEFAULT gen_random_uuid(),
  email TEXT NOT NULL UNIQUE,
  name TEXT NOT NULL,
  created_at TIMESTAMPTZ DEFAULT NOW()
);

CREATE INDEX idx_users_email ON users(email);
