OptionalbaseBase URL of the API. Defaults to https://ckan.govdata.de (only undefined
selects it). An http(s) URL without a query, fragment, whitespace or control
characters; otherwise the constructor throws.
OptionalmaxNumber of HTTP redirects (301/302/303/307/308) to follow, 0..20. Defaults to 5. Any other 3xx, one with a missing or malformed Location, and one past this limit surface as a GovDataApiError naming the target.
OptionalmaxHard cap on response body size in bytes (defends against memory exhaustion from a hostile/buggy endpoint). Defaults to 100 MiB; set to 0 for no limit.
OptionalmaxNumber of automatic retries for transient (429/503) responses and reset
connections, 0..MAX_RETRIES (10; default 2). Each waits retryDelayMs * attempt,
or longer if the response's Retry-After asks (up to MAX_RETRY_AFTER_MS; a longer
one is not retried, and the error names the requested wait).
OptionalonCalled once per retry, right before the backoff sleep, for each retried 429/503 and reset connection; never when there is no retry. A throw is swallowed.
OptionalretryBase backoff between retries in milliseconds (grows linearly); used without a
Retry-After. Default 200, at most MAX_RETRY_AFTER_MS.
OptionalsleepInjectable sleep, primarily for deterministic tests.
OptionaltimeoutPer-request timeout in milliseconds (default 30000; 0 disables; at most MAX_TIMEOUT_MS, 2^31 - 1 ms).
OptionaltransportSwappable transport. Defaults to the built-in node http/https transport.
OptionaluserValue of the User-Agent header (default govdata-cli). Must be sendable (see
assertHeaderValue): not blank, no control characters but tab, nothing above
U+00FF; otherwise the constructor throws GovDataValidationError.
Options for RequestEngine and the client. The numeric options must be integers within their documented range; anything else (negative, fractional, NaN, Infinity, too large) makes the constructor throw a GovDataError.
