Interface: ConnectionLike

client.ConnectionLike

Connection interface used by high level SDK clients.

NOTE: Currently the SDK only supports grpc-js based connection but in the future we might support grpc-web and native Rust connections.

Methods

close

close(): Promise<void>

Returns

Promise<void>


ensureConnected

ensureConnected(): Promise<void>

Returns

Promise<void>


withAbortSignal

withAbortSignal<R>(abortSignal, fn): Promise<R>

Set an AbortSignal that, when aborted, cancels any ongoing service requests executed in fn's scope. This will locally result in the request call throwing a grpc.ServiceError|ServiceError with code grpc.status.CANCELLED|CANCELLED; see isGrpcCancelledError.

Type parameters

Name
R

Parameters

NameType
abortSignalAbortSignal
fn() => Promise<R>

Returns

Promise<R>

value returned from fn

withDeadline

withDeadline<R>(deadline, fn): Promise<R>

Set a deadline for any service requests executed in fn's scope.

The deadline is a point in time after which any pending gRPC request will be considered as failed; this will locally result in the request call throwing a grpc.ServiceError|ServiceError with code grpc.status.DEADLINE_EXCEEDED|DEADLINE_EXCEEDED; see isGrpcDeadlineError.

It is stronly recommended to explicitly set deadlines. If no deadline is set, then it is possible for the client to end up waiting forever for a response.

This method is only a convenience wrapper around Connection.withDeadline.

Type parameters

Name
R

Parameters

NameTypeDescription
deadlinenumber | Datea point in time after which the request will be considered as failed; either a Date object, or a number of milliseconds since the Unix epoch (UTC).
fn() => Promise<R>-

Returns

Promise<R>

Set metadata for any service requests executed in fn's scope.

Type parameters
