Example of Web Application Development in Fantom Programming Language

Here are some examples of using Fantom for web applications. These examples highlight how Fantom can be applied to create simple yet functional web applications.

Example 1: Basic Web Server in Fantom

This example demonstrates how to set up a simple HTTP web server that listens to incoming requests and serves basic responses.

using fan.net._

class SimpleWebServer {

  fun startServer => {
    // Set up the server on port 8080
    server := HttpServer.bind(8080, {
      // Handle the incoming request
      fun handleRequest(req: HttpRequest) {
        // Send a response with a 'Hello, Fantom!' message
        resp := req.response
        resp.status(200)
        resp.contentType("text/plain")
        resp.write("Hello, Fantom!")
      }
    })
    // Start the server
    server.start
    echo "Server started on port 8080"
  }
}

Explanation:

• This example creates an HTTP server using Fantom’s HttpServer class. It listens for requests on port 8080 and responds with a simple “Hello, Fantom!” message.
• You can modify this server to handle different routes, process form submissions, or handle API requests.

Example 2: Handling a POST Request

In this example, a web server accepts a POST request with form data and responds accordingly.

using fan.net._
using fan.util._

class PostRequestExample {

  fun startServer => {
    server := HttpServer.bind(8080, {
      fun handleRequest(req: HttpRequest) {
        if (req.method == "POST") {
          // Read the form data from the request
          data := req.content
          echo "Received data: $data"

          // Send a response back to the client
          resp := req.response
          resp.status(200)
          resp.contentType("text/plain")
          resp.write("Data received: $data")
        }
        else {
          // Handle GET or other requests
          resp := req.response
          resp.status(200)
          resp.contentType("text/html")
          resp.write('<html><body><form method="POST"><input name="name"/><input type="submit"/></form></body></html>')
        }
      }
    })
    server.start
    echo "Server started on port 8080"
  }
}

Explanation:

• The server listens for both GET and POST requests. When it receives a POST request, it processes the data sent by the client (like form data), and responds with the received data.
• If the request is a GET request, it responds with an HTML form that allows the user to submit data via POST.

Example 3: Handling WebSockets for Real-Time Communication

Fantom’s WebSocket class can be used to create real-time applications like live chats, notifications, etc. Here’s a simple WebSocket server example:

using fan.net._

class WebSocketExample {

  fun startServer => {
    wsServer := WebSocketServer.bind(8080, {
      fun onOpen(ws: WebSocket) {
        echo "New client connected"
        ws.send("Welcome to the WebSocket server!")
      }

      fun onMessage(ws: WebSocket, msg: Str) {
        echo "Received message: $msg"
        ws.send("Echo: $msg")
      }

      fun onClose(ws: WebSocket) {
        echo "Client disconnected"
      }
    })
    wsServer.start
    echo "WebSocket server started on port 8080"
  }
}

• This WebSocket server accepts connections and sends an initial welcome message to clients.
• It echoes any message received from the client, which is useful for building real-time communication features like chat applications or live notifications.

Example 4: Creating a Simple API with JSON Response

This example shows how to create a simple API endpoint that responds with a JSON object, a common use case in modern web applications.

using fan.net._
using fan.util._

class JsonApiExample {

  fun startServer => {
    server := HttpServer.bind(8080, {
      fun handleRequest(req: HttpRequest) {
        if (req.path == "/api/data") {
          // Create a simple JSON object as response
          jsonData := Obj(
            "name" => "Fantom",
            "language" => "Programming",
            "type" => "Web Development"
          )
          resp := req.response
          resp.status(200)
          resp.contentType("application/json")
          resp.write(jsonData.toJson)
        } else {
          resp := req.response
          resp.status(404)
          resp.contentType("text/plain")
          resp.write("Page not found")
        }
      }
    })
    server.start
    echo "Server started on port 8080"
  }
}

• When a GET request is made to the /api/data endpoint, the server responds with a JSON object containing basic information about Fantom.
• If the requested path doesn’t exist, the server returns a 404 error.
