Leveraging Web APIs for Portable JavaScript Libraries

Built a Postgres client that runs on native web APIs using ArrayBuffer, TypedArray, DataView, TextEncoder/Decoder and Web Crypto, and it works across Node, Deno, Bun and browsers with tradeoffs. Highlights: Postgres client on native web APIs, array buffer slicing zero-copy and backpressure via web streams for pipeline composition. Benchmarks show 1.2× faster concat, 6× slower hex/base64 encoding, and webstreams 5× faster for one emit but 10–15× slower over 10k events. Missing native hex/B64 and buffer concat are practical limits.
