environment-variables

You can validate environment variables with Zod by defining schemas that enforce variable types and catch errors early during runtime. This Skill uses t3-env to centralize management and secure sensitive configuration across development and production environments.

To separate client and server environment variables securely, define them in distinct schemas within a central configuration file. This approach uses t3-env to clearly distinguish variables exposed to the client from those kept server-side, preventing sensitive data leaks.

The best way to manage type-safe environment variables is using t3-env and Zod to define shared, client, and server variables. This validates types at runtime and ensures configuration consistency across development and production environments.

Yes, t3-env works with Zod to provide runtime validation for application configuration. By defining Zod schemas, the integration enforces type safety and validates variable types before deployment, catching configuration errors early.

To add a new server-only API key, store it securely in your local environment file, then define its string schema in the centralized configuration file. Zod validates the key before deployment, ensuring it remains server-side and correctly typed.

You need runtime validation for environment variables because type definitions alone do not check actual values at execution. Using Zod schemas catches invalid or missing configurations early, preventing runtime errors and ensuring secure handling across environments.
