Demonstrates how to connect to an SSL server, send a simple message, receive a simple response, and disconnect. React Native

import { Socket } from '@chilkat/react-native'

async function chilkatExample() {
  // This example assumes the Chilkat API to have been previously unlocked.
  // See Global Unlock Sample for sample code.

  const socket = new Socket();

  const ssl = true;
  const maxWaitMillisec = 20000;

  // The SSL server hostname may be an IP address, a domain name,
  // or "localhost".  You'll need to change this:
  const sslServerHost = '123.123.88.88';
  const sslServerPort = 8123;

  // Connect to the SSL server:
  try {
    await socket.connectAsync(sslServerHost, sslServerPort, ssl, maxWaitMillisec);
  } catch {
    console.log(socket.lastErrorText);
    return;
  }

  // Set maximum timeouts for reading an writing (in millisec)
  socket.maxReadIdleMs = 20000;
  socket.maxSendIdleMs = 20000;

  // Send a "Hello Server! -EOM-" message:
  try {
    await socket.sendStringAsync('Hello Server! -EOM-');
  } catch {
    console.log(socket.lastErrorText);
    return;
  }

  // The server (in this example) is going to send a "Hello Client! -EOM-" 
  // message.  Read it:
  let receivedMsg: string;
  try {
    receivedMsg = await socket.receiveUntilMatchAsync('-EOM-');
  } catch {
    console.log(socket.lastErrorText);
    return;
  }

  // Close the connection with the server
  // Wait a max of 20 seconds (20000 millsec)
  await socket.closeAsync(20000);

  console.log(receivedMsg);
