Envkist

A utility to defer the resolution of environment variables.

Instead of reading the variables directly, declare specs for them and resolve on demand.

• Support different runtimes like browser, Node.js, Deno, Bun, Cloudflare
• Declare typed specs for environment variables with optional fallback values
• Type-guard checks to determine whether a value matches a desired spec
• Resolve specs to typed values at runtime with automatic type coercion
• Generate JavaScript source strings from specs for build-time code injection
