twilio-sync

What is twilio-sync?

The twilio-sync npm package provides a set of tools for synchronizing state across multiple devices and users in real-time. It is part of Twilio's suite of APIs and is designed to help developers build collaborative applications with ease.

What are twilio-sync's main functionalities?

Document

Documents are key-value stores that can be used to synchronize state across multiple clients. This example demonstrates how to create or access a document, listen for updates, and update the document.

const SyncClient = require('twilio-sync');
const client = new SyncClient('your_twilio_sync_token');

client.document('MyDocument').then((doc) => {
  doc.on('updated', (data) => {
    console.log('Document updated:', data);
  });
  return doc.update({ foo: 'bar' });
}).then((updatedDoc) => {
  console.log('Updated document:', updatedDoc);
}).catch((error) => {
  console.error('Error:', error);
});

List

Lists are ordered collections of items that can be used to synchronize lists of data across multiple clients. This example shows how to create or access a list, listen for new items, and add an item to the list.

const SyncClient = require('twilio-sync');
const client = new SyncClient('your_twilio_sync_token');

client.list('MyList').then((list) => {
  list.on('itemAdded', (item) => {
    console.log('Item added:', item);
  });
  return list.push({ foo: 'bar' });
}).then((item) => {
  console.log('Added item:', item);
}).catch((error) => {
  console.error('Error:', error);
});

Map

Maps are key-value stores where each key can have multiple fields. This example demonstrates how to create or access a map, listen for item updates, and set an item in the map.

const SyncClient = require('twilio-sync');
const client = new SyncClient('your_twilio_sync_token');

client.map('MyMap').then((map) => {
  map.on('itemUpdated', (item) => {
    console.log('Item updated:', item);
  });
  return map.set('key', { foo: 'bar' });
}).then((item) => {
  console.log('Set item:', item);
}).catch((error) => {
  console.error('Error:', error);
});

Stream

Streams are used to publish and subscribe to messages in real-time. This example shows how to create or access a stream, listen for new messages, and publish a message to the stream.

const SyncClient = require('twilio-sync');
const client = new SyncClient('your_twilio_sync_token');

client.stream('MyStream').then((stream) => {
  stream.on('messagePublished', (message) => {
    console.log('Message published:', message);
  });
  return stream.publishMessage({ foo: 'bar' });
}).then((message) => {
  console.log('Published message:', message);
}).catch((error) => {
  console.error('Error:', error);
});

Other packages similar to twilio-sync

firebase

Firebase is a comprehensive app development platform that includes real-time database capabilities. It allows for real-time synchronization of data across clients, similar to Twilio Sync. Firebase offers more extensive features such as authentication, hosting, and cloud functions, making it a more all-encompassing solution compared to Twilio Sync.

pusher

Pusher is a service that provides real-time APIs for building interactive applications. It offers channels for real-time communication, similar to Twilio Sync's streams. Pusher is known for its ease of use and quick setup, but it may not offer the same level of integration with other services as Twilio Sync.

ably

Ably is a real-time messaging service that provides pub/sub messaging, presence, and history features. It is similar to Twilio Sync in terms of real-time data synchronization but offers additional features like message history and presence tracking. Ably is designed to be highly scalable and reliable.
