Version 4.0.2

What's Changed

• fix: clear traits when identifying over previous identity by @kyle-ssg in #229

Full Changelog: 4.0.1...4.0.2

v4.0.1 Fix onChange Generic Types

Closes #224

v4.0.0 - add list of changed flags/traits, improve resolve/reject of init

This will be the first version compatible with OpenFeature. Merges #223

Breaking changes

• Init will now reject if:
  • No environment ID is provider
  • Fetch fails and there's no cache (Init resolves on cache)
  • There's no cache/defaults and preventFetch is true
• The boolean properties traitsChange and flagsChanged are now a string[] of changed keys or null. This reduces breaking changes since falsey and truthy checks will still behave as before.

Other changes

• Init is (finally) async/await
• Init code is reduced by pulling out isolated functions
• Added tests around init promises
• Organised util files

3.24.0 - Read cache synchronously

Closes #222

The SDK will now synchronously read cache rather than fetching it asynchronously.

3.23.2 - Remove busy logs, fix onChange event

Merges #207
Closes #217

3.23.1 - Prevent Nextjs caching behaviour

Merges #216

3.23.0 - Fix missed events in useFlags

Closes #214

• Fixes flag updates from useFlags
• Fixes flag updates where flagsmith.init is not called

3.22.1 - Support fallback for non-JSON evaluations

Merges #213, thanks to @levrik

3.22.0 - Prevent race condition between identify/getFlags

Prior to this release, clients that request identified/unidentified flags simultaneously could see the wrong results due to a race condition. Although this signifies incorrect usage of the SDK, this will no longer occur.

For more information see #205.

3.19.0 - Access Flagsmith loading state

This introduces a strategy to responding to loading state changes in flagsmith

The following will be exposed to Flagsmith:

export declare enum FlagSource {
    "NONE" = "NONE",
    "DEFAULT_FLAGS" = "DEFAULT_FLAGS",
    "CACHE" = "CACHE",
    "SERVER" = "SERVER",
}

export declare type LoadingState = {
    error: Error | null, // Current error, resets on next attempt to fetch flags
    isFetching: bool, // Whether there is a current request to fetch server flags
    isLoading: bool,  // Whether any flag data exists
    source: FlagSource //Indicates freshness of flags
}

It can be consumed via the onChange function of flagsmith.init or the newly introduced useFlagsmithLoading

    onChange?: (previousFlags: IFlags<F> | null, params: IRetrieveInfo, loadingState:LoadingState) => void;
    const loadingState:LoadingState = useFlagsmithLoading()
