Class Method Details

.config!(url = nil) ⇒ Boolean

Applies a remote JSON hash containing the ENV keys and values from a remote URL. Values from the JSON hash are only applied to the current ENV hash ONLY if it does not already have a value. Therefore local ENV values will take precedence over remote ones. By default, it uses the url in environment value in 'CONFIG_URL' or 'HYPERDRIVE_URL'.

Parameters:

  • url (String) (defaults to: nil) —

    the remote url that responds with the JSON body.

Returns:

  • (Boolean) —

    true if the JSON hash was found and applied successfully.
