flags-sdk

Set up and use feature flags and A/B tests with the Flags SDK (flags npm package) and Vercel Flags. Use when installing or configuring the SDK, adding a new or existing flag, wiring vercelAdapter (OIDC or SDK keys), declaring flags with flag(), using the vercel flags CLI (create, inspect, list, enable, disable, set, update, split, rollout, rules, segments, use-targeting, evaluations, versions, open, archive, unarchive, rm, sdk-keys, override, prepare), setting up providers/adapters (Vercel, Statsig, LaunchDarkly, PostHog, GrowthBook, Global Config, OpenFeature, Split, Flagsmith, Reflag, Optimizely, or custom), precompute, identify/dedupe, Flags Explorer/Toolbar, Next.js or SvelteKit, or encrypting flag values. Triggers: feature flags, feature gates, A/B testing, experimentation, gradual rollout, traffic split, targeting rules, flag overrides, precompute, Flags Explorer, Vercel Flags, vercel flags CLI, flags/next, flags/sveltekit, flags/react, @flags-sdk/*.
