env-vars

You manage Vercel environment variables by scoping configurations to specific environments like development or production. This involves using `.env` file conventions and `vercel env` CLI commands to pull and configure environment-specific settings.

The OIDC token lifecycle in Vercel involves managing tokens for secure authentication throughout their creation, usage, and expiration. Proper lifecycle management ensures your applications maintain secure access without manual token rotation disruptions.

You pull environment variables locally by running the `vercel env pull .env.local` command. This retrieves your scoped environment configurations and writes them directly into a local `.env` file for development use.

Yes, the `vercel env` CLI commands allow you to add, remove, and pull environment-specific configurations. This ensures your development, preview, and production environments maintain distinct and secure variable scopes.

Standard `.env` file conventions involve using files like `.env.local` for local development and pulling scoped variables from the Vercel platform. This keeps configuration management consistent and prevents local secrets from reaching production.

OIDC tokens require dedicated lifecycle management because they are dynamic authentication credentials, unlike static environment variables. Handling them properly ensures secure authentication flows and prevents token expiration from breaking application access.
