2.0.0 (2024-03-22)

The 2.0.0 release introduces a number of new features and QoL improvements, including a new way to remove bloat and reduce the bundle size of your ably-js client, first-class support for Promises, a more idiomatic approach to using ably-js' React Hooks, enhancements to TypeScript typings, and more.

Below is an overview of the major changes in this release.

Please refer to the ably-js v2 lib migration guide and React Hooks migration guide for the full details, including a list of all breaking changes and instructions on how to address them.

Bundle Size Reduction

The default bundle size for the web has been reduced by ~32% compared to v1 - from 234.11 KiB to 159.32 KiB. When calculated with gzip compression, the reduction is ~30%, from 82.54 KiB to 57.9 KiB.

Additionally, by utilizing the new modular variant of the library (see below) and JavaScript tree shaking, you can create your own minimal useful Realtime client and achieve a bundle size reduction of ~60.5% compared to v1 - from 234.11 KiB to 92.38 KiB (or ~66% for gzip: from 82.54 KiB to 28.18 KiB).

Modular variant of the library

An ESM variant of the library is now available for browsers (but not for Node.js) via import from ably/modular. This modular variant of the library supports tree shaking, allowing for a reduction in the Ably bundle size within your application and improving the user experience. It can also be used by Web Workers.

React Hooks changes

React Hooks, exported at ably/react, now require the new ChannelProvider component to define the channels you wish to use and the options for them. This addresses the complexities previously encountered with useChannel and usePresence hooks when attempting to dynamically change options for a channel and provides a more straightforward approach to set and manage these options.

The functionality of the usePresence hook has been split into two separate hooks: usePresence, which is now used only to enter presence, and usePresenceListener, which is used to listen for presence updates. These new hooks offer better control over the desired presence behavior in your React components.

First-class support for Promises

The callbacks API has been entirely removed, and the library now supports promises for all its asynchronous operations by default.

TypeScript typings

The Types namespace has been removed. All types it contained are now exported at the top level.

Browser and Web Worker bundles

• The browser bundle now relies on the native Web Crypto API instead of CryptoJS. The ably/build/ably.noencryption bundle has been removed, as it is no longer necessary.
• The browser bundle can now be directly used by Web Workers. The ably/build/ably-webworker bundle has been removed, as it is no longer necessary.

Supported platforms changes

• Support for Internet Explorer has been dropped.
• Support for Node.js versions lower than 16 has been dropped. The supported Node.js versions are now 16, 18, and 20.
• The minimum supported versions for major browsers are: Chrome 58, Firefox 52, Edge 79, Safari 11, and Opera 45.
