3.0.0

[3.0.0] - 2022-12-07

The latest version of this SDK supports LaunchDarkly's new custom contexts feature. Contexts are an evolution of a previously-existing concept, "users." For more information please read the JavaScript SDK's latest release notes.

For detailed information about this version, please refer to the list below. For information on how to upgrade from the previous version, please read the migration guide.

Added:

• The context provider configuration option has been added.

Fixed:

• We fixed a bug where using native Object functions on the flags proxy object results in errors. This was reported in issue #162.

Deprecated:

• The user provider configuration option has been deprecated. Please use context instead.

2.29.3

[2.29.3] - 2022-12-07

Fixed:

• We fixed a bug where using native Object functions on the flags proxy object results in errors. This was reported in issue #162.

2.29.2

[2.29.2] - 2022-10-28

Fixed:

• An issue with asyncWithLDProvider that was causing flags to be empty on first render.

2.29.1

[2.29.1] - 2022-10-21

Changed:

• Upgraded to js-client-sdk version 2.24.2 which includes implementations of jitter and backoff for streaming connections. When a connection fails the retry will start at the streamReconnectDelay and will double on each unsuccessful consecutive connection attempt (backoff) to a max of 30 seconds. The delay will be adjusted from 50%-100% of the calculated delay to prevent many clients from attempting to reconnect at the same time (jitter).

2.29.0

[2.29.0] - 2022-10-18

Changed:

• Updated js-client-sdk to 2.24.0 which added support for Inspectors that can be used for collecting information for monitoring, analytics, and debugging.

2.28.0

[2.28.0] - 2022-10-05

Changed:

• Updated js-client-sdk version which removed event de-duplication functionality which was made redundant by support of summary events. This will improve the default event behavior when using experimentation.

2.27.0

[2.27.0] - 2022-08-31

Added:

• useFlags hook is now generically typed, allowing you to assert what type your flag set will be.
• useLDClientError hook for exposing client initialization failures.

Changed:

• sendEventsOnlyForVariation is now set to true by default to prevent a flag evaluation event being generated for every flag on load.
• flags object (that is either injected via props using LDConsumer or returned from the useFlags hook) will generate a flag evaluation event on flag read (using a JavaScript proxy). This can be disabled by setting reactOptions.sendEventsOnFlagRead: false.
• upgraded from ES5 to ES6.

2.26.0

[2.26.0] - 2022-04-27

Added:

• LDOptions.application, for configuration of application metadata that may be used in LaunchDarkly analytics or other product features. This does not affect feature flag evaluations.
• Added basicLogger, a replacement for the deprecated createConsoleLogger.

Fixed:

• The baseUrl, streamUrl, and eventsUrl properties now work properly regardless of whether the URL string has a trailing slash. Previously, a trailing slash would cause request URL paths to have double slashes.

2.25.2

[2.25.2] - 2022-04-15

Changed:

• Updated LDProvider and the SDK's peer dependencies so that it can run in an application with React 18 (#129)

2.25.1

[2.25.1] - 2022-02-18

Fixed:

• If the SDK receives invalid JSON data from a streaming connection (possibly as a result of the connection being cut off), it now uses its regular error-handling logic: the error is emitted as an error event or, if there are no error event listeners, it is logged. Previously, the error would be thrown as an unhandled exception.
