vite-plugin-env-schema

A Vite plugin (v1.0.2) for build-time validation and injection of environment variables using schema libraries like Zod, Valibot, ArkType, and Effect Schema via the Standard Schema V1 spec. It validates .env values against a defined schema early in the Vite config resolution (or on module load) and exposes them through a virtual module `virtual:env`. Key differentiators from other env plugins (e.g., @julr/vite-plugin-validate-env) include full compatibility with any Standard Schema library and zero runtime dependencies beyond the schema library. Released in July 2025 with an active maintenance cadence.
