Twine Client Library

The twine-client-library package allows users to interact with their Twine Realtime service from their client-side code.

Installation

Copy this code into your JavaScript code as an ES module package:

import TwineClientLibrary from 'https://cdn.jsdelivr.net/npm/twine-client-library@1.0/+esm';

Initialization

To configure the client, use the TwineClientLibrary constructor:

const host = 'https://your-twine-domain.com';
const twineClient = new TwineClientLibrary(host);

Once the constructor has been invoked, a connection is established with your Twine server.

Usage

connect & disconnect

Your twine-client-library instance will automatically connect with the server, but if you need to manually connect/disconnect the connect and disconnect` methods will do just that:

twineClient.connect();

twineClient.disconnect();

disconnectBtn.addEventListener('click', (e) => {
  e.preventDefault();
  twineClient.disconnect();
  setTimeout(() => {
    twineClient.connect();
  }, 10000)
});

subscribe

The subscribe method takes a single room_id (string) as an argument and subscribes the user to this room on the twine server.

twineClient.subscribe(room);

dropdown.addEventListener('change', () => {
  const room = dropdown.value;
  twineClient.subscribe(room);
});

unsubscribe

The unsubscribe method takes a single room_id (string) as an argument and unsubscribes the user to this room on the twine server.

twineClient.unsubscribe(room);

dropdown.addEventListener('change', () => {
  const room = dropdown.value;
  twineClient.unsubscribe(room);
});

listenOn

The listenOn method takes a room_id (string) and a callback function as arguments. The method will then listen for incoming messages to the room_id specified. When a message arrives that matches the room_id passed to listenOn, the callback function will be invoked.

twineClient.listenOn(room, callback);

twineClient.listenOn("room A", (data) => {
  console.log(data)
  // code will be executed everytime an event with a matching `room_id` occurs
});
