dotenv allows you to store env values in the .env file. envconfig handles normalizing the various ENV values from providers into a single configuration. Every provider has a different env value, such as POSTMARK_SMTP_SERVER, or SENDGRID_SMTP_SERVER. envconfig knows about these and provides a single service agnostic interface to that information. .env and envconfig work very well together.
