API Example

• Create main.py

  from datetime import datetime, timedelta
  
  from panther import status, Panther
  from panther.app import GenericAPI
  from panther.response import Response
  
  
  class FirstAPI(GenericAPI):
      # Cache Response For 10 Seconds
      cache = True
      cache_exp_time = timedelta(seconds=10)
      
      def get(self):
          date_time = datetime.now().isoformat()
          data = {'detail': f'Hello World | {date_time}'}
          return Response(data=data, status_code=status.HTTP_202_ACCEPTED)
  
  
  url_routing = {'': FirstAPI}
  app = Panther(__name__, configs=__name__, urls=url_routing)

• Run the project:

  • $ panther run --reload

• Checkout the http://127.0.0.1:8000/

WebSocket Echo Example

• Create main.py

  from panther import Panther
  from panther.app import GenericAPI
  from panther.response import HTMLResponse
  from panther.websocket import GenericWebsocket
  
  
  class FirstWebsocket(GenericWebsocket):
      async def connect(self, **kwargs):
          await self.accept()
  
      async def receive(self, data: str | bytes):
          await self.send(data)
  
  
  class MainPage(GenericAPI):
      def get(self):
          template = """
          <input type="text" id="messageInput">
          <button id="sendButton">Send Message</button>
          <ul id="messages"></ul>
          <script>
              var socket = new WebSocket('ws://127.0.0.1:8000/ws');
              socket.addEventListener('message', function (event) {
                  var li = document.createElement('li');
                  document.getElementById('messages').appendChild(li).textContent = 'Server: ' + event.data;
              });
              function sendMessage() {
                  socket.send(document.getElementById('messageInput').value);
              }
              document.getElementById('sendButton').addEventListener('click', sendMessage);
          </script>
          """
          return HTMLResponse(template)
  
  url_routing = {
      '': MainPage,
      'ws': FirstWebsocket,
  }
  app = Panther(__name__, configs=__name__, urls=url_routing)

• Run the project:

  • $ panther run --reload

• Go to http://127.0.0.1:8000/ and work with your websocket
