Properties

Optional cacheMiddleware

cacheMiddleware?: boolean

Default false.

When true, the client will only resolve the middleware stack once per Command class. This means modifying the middlewareStack of the command or client after requests have been made will not be recognized.

Calling client.destroy() also clears this cache.

Enable this only if needing the additional time saved (0-1ms per request) and not needing middleware modifications between requests.

Optional defaultsMode

defaultsMode?: DefaultsMode | Provider<DefaultsMode>

The @smithy/smithy-client#DefaultsMode that will be used to determine how certain default configuration options are resolved in the SDK.

Optional disableHostPrefix

disableHostPrefix?: boolean

Disable dynamically changing the endpoint of the client based on the hostPrefix trait of an operation.

Optional extensions

extensions?: RuntimeExtension[]

Optional extensions

Optional logger

logger?: Logger

Optional logger for logging debug/info/warn/error.

Optional maxAttempts

maxAttempts?: number | Provider<number>

Value for how many times a request will be made at most in case of retry.

Optional region

region?: string | Provider<string>

The AWS region to which this client will send requests

Optional requestHandler

requestHandler?: HttpHandlerUserInput

The HTTP handler to use or its constructor options. Fetch in browser and Https in Nodejs.

Optional retryMode

retryMode?: string | Provider<string>

Specifies which retry algorithm to use.
