@steppingblocks/stdin-secret-to-env v0.1.3

Intended usage:

aws secretsmanager get-secret-value --secret-id local/my-project --profile development | npx stdin-secret-to-env@latest > .env.local

Where the local/my-project secret is a multi-line env file stored as plaintext.

However, it could be used to pull a single top-level value from any JSON string
