Feature Flags System

A personal learning project exploring Azion Edge Functions with a feature flags system. Consists of two main components:

• Edge Function (function/) — TypeScript/Hono service for serving flag snapshots at the edge
• Go API (api/) — REST API for managing flags, backed by Redis

Quick Start

Edge Function

cd function
npm install
npm run dev

See function/README.md for full setup and deployment.

Go API

cd api
go mod tidy
go run ./cmd/api

See api/README.md for full setup and deployment.

Architecture

Refer to:

• PRD.md — Complete product specification
• function/ARCHITECTURE.md — Edge Function design
• api/ARCHITECTURE.md — Go API design
