Changelog: Twilio Chat JavaScript SDK



Programmable Chat has been deprecated and is no longer supported. Instead, we'll be focusing on the next generation of chat: Twilio Conversations. Find out more about the EOL process here(link takes you to an external page).

If you're starting a new project, please visit the Conversations Docs to begin. If you've already built on Programmable Chat, please visit our Migration Guide to learn about how to switch.

Support for previous versions of the Chat SDKs

Twilio Programmable Chat SDKs use Semantic Versioning(link takes you to an external page). Twilio supports version N-1 for 12 months after the first GA release of version N. We recommend that you upgrade to the latest version as soon as possible to avoid any breaking changes. Version 5.x is the latest generation of the Javascript client SDK.

Support for 4.x will cease on May 17, 2022. Please upgrade to the latest version.

Support for 3.x ceased on July 17, 2021.

End-of-Life for 2.x occurred on May 18, 2020.

End-of-Life for 1.x occurred on June 30, 2019.

Links are provided to specific patch versions here. We don't recommend using these links unless you have a specific need for a certain patch of a release.

changes page anchor
  • Bump Node required version to current LTS (14).
  • Default exports are removed in favor of named exports.
  • Should now work with React Native and Angular.
  • Added .onWithReplay() function to Conversation entities which could be used to subscribe to an event with replay. Upon subscribing, the most recent event (if any) will be re-emitted.

Programmable Chat 5.0.2 (July 16, 2021)

programmable-chat-502-july-16-2021 page anchor
  • Fix compilation of TS with type exports, broken since 5.0.1.

Programmable Chat 5.0.1 (June 30, 2021)

programmable-chat-501-june-30-2021 page anchor
  • Fixed polyfills for IE11.
  • As part of the above fix, the package build process was also upgraded from gulp to rollup . Unfortunately, this caused change in the type exports. While not affecting the deployments in the wild, it made TS compilation impossible. The fix for it is deployed in 5.0.2 so please do not use this version explicitly.

Programmable Chat 5.0.0 (May 17, 2021)

programmable-chat-500-may-17-2021 page anchor
  • Major internals improvement (the "Sessionless" protocol). This improvement is designed primarily for improved reliability. While this is not a breaking code change, it does carry a meaningful impact on timing:
    • SDK commands will return success or failure up to ~10% more quickly than before.
    • Real-time updates of data is now likely to arrive after the command completes. For example, Channel.updateAttributes() will resolve successfully while Channel#attributes still contains the old value. To see the new value, we recommend waiting for an #updated event.
  • Passing null to Channel.sendMessage will result with the message body being an empty string.
  • User.updateFriendlyName no longer accepts null as the value.
  • Channel.updateFriendlyName no longer accepts null as the value.
