envshape

Overview

envshape catches missing, mistyped, and unexpected environment variables before an application starts. The 1.2.0 API adds explicit package metadata, primitive-type introspection, reusable value validation, and richer TypeScript documentation.

Structured API

Canonical package: @theworker02/envshape

import { checkEnv, validateValue, ENV_TYPES, PACKAGE } from "@theworker02/envshape";

const result = checkEnv({ PORT: "number" }, { PORT: "8080" });
console.log(result.ok, validateValue("bool", "true"), ENV_TYPES, PACKAGE.version);

Generated symbol documentation is available directly on JSR.
