Javascript-SDK - 3.1.0
5 min
[3.1.0] - April 22nd, 2019
New Features:
- Introduced Decision notification listener to be able to record:
- Variation assignments for users activated in an experiment.
- Feature access for users.
- Feature variable value for users.
Changed
- New APIs for setting logger and logLevel on the optimizelySDK singleton (#232)
- logger and logLevel are now set globally for all instances of Optimizely. If you were passing different loggers to individual instances of Optimizely, logging behavior may now be different.
Setting a ConsoleLogger
var optimizelySDK = require('@optimizely/optimizely-sdk')
// logger and logLevel are now set on the optimizelySDK singleton
optimizelySDK.setLogger(optimizelySDK.logging.createLogger())
// valid levels: 'DEBUG', 'INFO', 'WARN', 'ERROR'
optimizelySDK.setLogLevel('WARN')
// enums can also be used
optimizelySDK.setLogLevel(optimizelySDK.enums.LOG_LEVEL.ERROR)Disable logging
var optimizelySDK = require('@optimizely/optimizely-sdk')
optimizelySDK.setLogger(null)Bug Fixes
- Feature variable APIs now return default variable value when featureEnabled property is false. (#249)
Deprecated
- Activate notification listener is deprecated as of this release. Recommendation is to use the new Decision notification listener. Activate notification listener will be removed in the next major release.
