🛠 Statsig + OTel DevTools

Enterprise-grade feature flag and configuration override tooling for browser-based apps.

⚡ Quick Cheatsheet

Action	Command in Console
Inspect overrides	adapter.inspect()
Enable a gate	adapter.setGate('new_onboarding_flow', true)
Override config	adapter.setConfig('api_timeout_ms', 500)
Clear all overrides	adapter.clear()

🏗 Architecture

1. Parent-Based OpenTelemetry sampling: preserves distributed trace continuity across service transitions.
2. Typed local overrides: gate and config values are stored separately in browser localStorage.
3. Enterprise diagnostics: inspect() logs structured gates and configs for rapid audit.

🚀 Usage

import { LocalOverrideAdapter } from './src/adapter';

interface AppFeatureFlags {
  new_onboarding_flow: boolean;
  premium_dashboard: boolean;
  api_timeout_ms: number;
  theme_config: { primaryColor: string; darkMode: boolean };
}

const adapter = new LocalOverrideAdapter<AppFeatureFlags>('my-app-key');
adapter.setGate('new_onboarding_flow', true);
adapter.setConfig('api_timeout_ms', 500);
adapter.inspect();
