Interface ConnectOptions

Options used when connecting to a Fabric Gateway.

Example

function defaultTimeout(): grpc.CallOptions {
    return {
        deadline: Date.now() + 5000, // 5 second timeout
    };
};
const options: ConnectOptions {
    identity: {
        mspId: 'myorg',
        credentials,
    },
    signer: signers.newPrivateKeySigner(privateKey),
    client: new grpc.Client('gateway.example.org:1337', grpc.credentials.createInsecure()),
    evaluateOptions: defaultTimeout,
    endorseOptions: defaultTimeout,
    submitOptions: defaultTimeout,
    commitStatusOptions: defaultTimeout,
};
interface ConnectOptions {
    blockAndPrivateDataEventsOptions?: (() => CallOptions);
    blockEventsOptions?: (() => CallOptions);
    chaincodeEventsOptions?: (() => CallOptions);
    client: GrpcClient;
    commitStatusOptions?: (() => CallOptions);
    endorseOptions?: (() => CallOptions);
    evaluateOptions?: (() => CallOptions);
    filteredBlockEventsOptions?: (() => CallOptions);
    hash?: Hash;
    identity: Identity;
    signer?: Signer;
    submitOptions?: (() => CallOptions);
    tlsClientCertificateHash?: Uint8Array;
}

Properties

OptionalblockAndPrivateDataEventsOptions

blockAndPrivateDataEventsOptions?: (() => CallOptions)

Supplier of default gRPC CallOptions for block and private data events.

OptionalblockEventsOptions

blockEventsOptions?: (() => CallOptions)

Supplier of default gRPC CallOptions for block events.

OptionalchaincodeEventsOptions

chaincodeEventsOptions?: (() => CallOptions)

Supplier of default gRPC CallOptions for chaincode events.

client

client: GrpcClient

A gRPC Client connection to a Fabric Gateway. This should be shared by all gateway instances connecting to the same Fabric Gateway. The client connection will not be closed when the gateway is closed.

OptionalcommitStatusOptions

commitStatusOptions?: (() => CallOptions)

Supplier of default gRPC CallOptions for retrieving transaction commit status.

OptionalendorseOptions

endorseOptions?: (() => CallOptions)

Supplier of default gRPC CallOptions for endorsements.

OptionalevaluateOptions

evaluateOptions?: (() => CallOptions)

Supplier of default gRPC CallOptions for evaluating transactions.

OptionalfilteredBlockEventsOptions

filteredBlockEventsOptions?: (() => CallOptions)

Supplier of default gRPC CallOptions for filtered block events.

Optionalhash

hash?: Hash

Hash implementation used by the gateway to generate digital signatures. If this option is not specified, SHA-256 is used by default.

identity

identity: Identity

Client identity used by the gateway.

Optionalsigner

signer?: Signer

Signing implementation used to sign messages sent by the gateway.

OptionalsubmitOptions

submitOptions?: (() => CallOptions)

Supplier of default gRPC CallOptions for submit of transactions to the orderer.

OptionaltlsClientCertificateHash

tlsClientCertificateHash?: Uint8Array

SHA-256 hash of the TLS client certificate. This option is required only if mutual TLS authentication is used for the gRPC connection to the Gateway peer.
