fetch-aws4

Thin wrapper around the native fetch API that automatically signs HTTP requests with AWS Signature V4 using credentials from environment variables or explicit options. Version 3.0.0 is ESM-only, ships TypeScript definitions, and supports custom wrappers via the exported `wrapper` function. It is lightweight with no external runtime dependencies, making it ideal for serverless environments and Node.js 18+. Unlike alternatives, it does not bundle its own fetch implementation, relying on the platform's native fetch.
