CRUD Example

A complete CRUD (Create, Read, Update, Delete) example with Vegaa.

Code​

import { vegaa, route, corsPlugin, bodyParserPlugin } from 'vegaa'

// Mock database
const db = {
  1: { id: 1, name: 'Alice', email: 'alice@example.com' },
  2: { id: 2, name: 'Bob', email: 'bob@example.com' }
}

async function main() {
  // Register plugins
  await vegaa.plugin(corsPlugin)
  await vegaa.plugin(bodyParserPlugin)
  
  console.log('✅ Plugins registered')

  // GET all users
  route('/users').get(() => {
    return {
      users: Object.values(db),
      total: Object.keys(db).length
    }
  })

  // GET single user
  route('/users/:id').get((id) => {
    const user = db[Number(id)]
    if (!user) {
      return { error: 'User not found' }
    }
    return user
  })

  // POST create user
  route('/users').post((body) => {
    if (!body?.name || !body?.email) {
      return { error: 'Missing name or email' }
    }

    const id = Math.max(0, ...Object.keys(db).map(Number)) + 1
    const newUser = { id, name: body.name, email: body.email }
    db[id] = newUser
    
    return { message: 'User created', user: newUser }
  })

  // PUT update user
  route('/users/:id').put((params, body) => {
    const id = Number(params.id)
    if (!db[id]) {
      return { error: 'User not found' }
    }

    db[id] = { ...db[id], ...body }
    return { message: 'User updated', user: db[id] }
  })

  // DELETE user
  route('/users/:id').delete((id) => {
    const user = db[Number(id)]
    if (!user) {
      return { error: 'User not found' }
    }

    delete db[Number(id)]
    return { message: `User ${id} deleted` }
  })

  // Start server
  await vegaa.startVegaaServer({ port: 4000 })
  console.log('✅ Server running on http://localhost:4000')
}

main().catch(err => {
  console.error('💥 Server failed:', err)
  process.exit(1)
})

Try It​

Test It​

# Get all users
curl http://localhost:4000/users

# Get single user
curl http://localhost:4000/users/1

# Create user
curl -X POST http://localhost:4000/users \
  -H "Content-Type: application/json" \
  -d '{"name":"Charlie","email":"charlie@example.com"}'

# Update user
curl -X PUT http://localhost:4000/users/1 \
  -H "Content-Type: application/json" \
  -d '{"name":"Alice Updated"}'

# Delete user
curl -X DELETE http://localhost:4000/users/1

Key Concepts​

  • GET Routes - Parameters are flattened (id instead of params.id)
  • POST/PUT Routes - Parameters are grouped (params, body)
  • Body Parsing - bodyParserPlugin automatically parses JSON bodies
  • Error Handling - Return error objects for failed operations
