Feature flag rollouts

1. Define the flag

Create a flag in the Meridian dashboard under Experiments → Flags. Give it a key like beta_dashboard_v2.

2. Target your audience

Choose a rollout percentage or target by license tier, geography, or a custom attribute you pass at runtime. Meridian evaluates rules server-side before the page renders.

3. Consume in code

Call the Meridian edge helper inside your page or API route. The flag value is resolved from the request context — no client-side flicker.

import { getFlag } from '@meridian/edge'

export default async function Dashboard() {
  const v2 = await getFlag('beta_dashboard_v2', req)
  return v2 ? <V2 /> : <V1 />
}

4. Monitor & roll back

Every evaluation is logged. Watch error rates and latency in the flag detail view. If something breaks, set the flag to 0% — the change takes effect on the next request with zero propagation delay.
