const port = process.env.PORT || 3000

// Middleware
app.use(express.json())
app.use(express.urlencoded({ extended: true }))

// Routes
app.get('/', (req, res) => {
  res.send('Hello World!')
})

// Start server
app.listen(port, () => {
  console.log(`Server running on port ${port}`)
})

TypeScript Example

// Type: express-server-ts
import express, { Application, Request, Response } from 'express'
const app: Application = express()
const port: string | number = process.env.PORT || 3000

app.use(express.json())
app.get('/', (req: Request, res: Response) => {
  res.send('Hello World!')
})

app.listen(port, () => {
  console.log(`Server running on port ${port}`)
})

⚛️ React Examples

/// Type: exp-fetch-react
const fetchData = async () => {
  try {
    const response = await fetch('http://localhost:3000/api')
    const data = await response.json()
    return data
  } catch (error) {
    console.error('Error:', error)
    throw error
  }
}

React Typescript Examples

// Type: exp-fetch-react-ts
interface ApiResponse<T> {
  success: boolean
  data?: T
  error?: string
}

const fetchData = async <T>(url: string): Promise<T> => {
  try {
    const response = await fetch(url)
    const result: ApiResponse<T> = await response.json()
    return result.data!
  } catch (error) {
    console.error('Error:', error)
    throw error
  }
}
