dotenv

Load environment variables from a .env file into Node.js by parsing the file contents at startup and populating process.env with the required keys, secrets, and API URLs. This prevents misconfigurations and accidental exposure.

Variable expansion and command substitution are supported when parsing .env contents. This mechanism handles common configuration gotchas, enabling secure local development and reliable deployments across CI and staging environments.

Manage secrets and API keys for local development by storing them in a .env file and loading values at application startup. This automatically configures database URLs and prevents accidental secret exposure in the Node.js runtime.

Use environment variables consistently across local, CI, and staging by loading a .env file into process.env at startup. This wires secrets, API keys, and database URLs reliably across all deployment contexts without misconfiguration.

Validate environment variable keys before deploying to production to prevent runtime issues caused by missing or misconfigured secrets and database URLs. Key validation ensures required variables are present and correctly populated in process.env.
