Service Client Interface

Defines the configuration interface for an AWS service client, such as the S3 client. It extends from a base client configuration and includes service-specific options.

{"interface S3ClientConfig extends SmithyClientConfig {endpoint?: HttpEndpoint, forcePathStyle?: boolean, useAccelerateEndpoint?: boolean, ...}}

Command Interface

Represents a command interface that defines input and output types for a specific operation. It also includes methods for resolving middleware in the command's execution stack.

{"interface Command<InputType extends object, OutputType extends object, ResolvedClientConfiguration, ClientInput extends InputType = InputType, ClientOutput extends OutputType = OutputType> {resolveMiddleware(stack: MiddlewareStack<ServiceInputTypes, ServiceOutputTypes>, configuration: ResolvedClientConfiguration): Handler<ClientInput, ClientOutput>; ...}}

Middleware Stack

Defines the middleware stack interface used in the AWS SDK. Middleware are functions that can modify requests and responses or handle specific tasks like logging or error handling.

{"interface MiddlewareStack<Input extends object, Output extends object> {add(middleware: MiddlewareType<Input, Output>, options?: MiddlewareStackOptions): void; addRelativeTo(middleware: MiddlewareType<Input, Output>, options: RelativeMiddlewareOptions): void; ...}}
