User Segment Targeting

Flags can have targeting rules to serve specific variants to user groups based on attributes:
1

Define Rules

Set rules in the dashboard using attributes (e.g., jobTitle = "QA Tester").

2

Evaluate Clauses

Within a rule, clauses use logical OR—e.g., serve “Enabled” to users with jobTitle of “QA Tester” or “PM”.
import { FlagSyncFactory } from '@flagsync/js-sdk';

const factory = FlagSyncFactory({
  sdkKey: 'your-sdk-key',
  core: {
    key: 'user123',
    attributes: { jobTitle: 'QA Testers' }
  }
});
3

Apply First Match

If a flag has multiple rules, the first matching rule determines the variant served.
4

Halt Evaluation

A matched rule stops further evaluation; otherwise, it proceeds to Rollouts.
