𝗧𝗵𝗶𝘀 𝗜𝘀 𝗔 𝗛𝗲𝗮𝗱𝗹𝗶𝗻𝗲 You need a robust feature flag system to experiment safely and roll out changes gradually. Here's how you can build a real-time, event-sourced feature flag system with Rust and WebAssembly:

• You'll learn about event sourcing for feature flags and how it improves auditability and rollbacks
• You'll design a compact event schema for feature flag lifecycle events
• You'll implement a Rust event store with append-only logs and snapshotting
• You'll expose a WASM module that can be embedded in frontend apps to evaluate feature flags with minimal latency Key components include:
• Event Store (Rust): an append-only log backed by a simple file-based database
• WASM Client (Rust/WASM): a small library compiled to WebAssembly that provides a high-performance feature flag evaluator
• API Server (Node.js): a tiny HTTP server that serves the WASM module and streams updates to clients via Server-Sent Events To get started, you'll need knowledge of Rust basics and WebAssembly.
