Environment Variables Don't Have to Suck

Short summary

The author released ctroenv, a lightweight open-source library that eliminates repetitive environment variable validation boilerplate. Define a schema once to get typed objects back with automatic coercion, validation, and secrets masking, with errors surfacing at startup rather than production. CLI tools validate configs in CI pipelines, and it supports Node 18+, Bun, Deno, and Cloudflare Workers with zero dependencies.
