Release Notes

launchdarkly/node-server-sdk (launchdarkly-node-server-sdk)

v6.4.3

Compare Source

Fixed:

• The TestDataRuleBuilder was using an incorrect field name for operators, which would prevent rules from working correctly with the TestData feature. (Thanks, LiamMorrow!)

v6.4.2

Compare Source

Changed:

• Enforce a 64 character limit for application.id and application.version configuration options.

v6.4.1

Compare Source

Fixed:

• When using polling mode (stream: false), if the SDK was shut down with close(), a timer task could still remain active for up to 30 seconds (or whatever the polling interval was set to).

v6.4.0

Compare Source

This release is functionally identical to the 6.3.1 release. It exists for compliance with semantic versioning, and to correct the changelog: the new feature described below was accidentally omitted from the changelog, and the minor version number should have been incremented.

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.

v6.3.1

Compare Source

Fixed:

• Removed a transitive dependency on the package url-parse, which was flagged in CVE-2022-0686.

v6.3.0

Compare Source

Added:

• TestData, in the new module launchdarkly-node-server-sdk/integrations, is a new way to inject feature flag data programmatically into the SDK for testing—either with fixed values for each flag, or with targets and/or rules that can return different values for different users. Unlike the file data source, this mechanism does not use any external resources, only the data that your test code has provided.
• launchdarkly-node-server-sdk/integrations is the new preferred module for importing FileDataSource and the FileDataSourceOptions type.

Deprecated:

• The FileDataSource and FileDataSourceOptions exports from the main module are now deprecated.
