OptionaladdressThe address of the Temporal server to connect to, in hostname:port format.
Port defaults to 7233. Raw IPv6 addresses must be wrapped in square brackets (e.g. [ipv6]:port).
OptionalapiAPI key for Temporal. This becomes the "Authorization" HTTP header with "Bearer " prepended.
This is mutually exclusive with the Authorization header in ConnectionOptions.metadata.
You may provide a static string or a callback. Also see Connection.withApiKey or Connection.setApiKey
OptionalcallgRPC call credentials.
CallCredentials generaly modify metadata; they can be attached to a connection to affect all method
calls made using that connection. They can be created using some of the factory methods defined
here
If callCredentials are specified, they will be composed with channel credentials
(either the one created implicitely by using the tls option, or the one specified
explicitly through credentials). Notice that gRPC doesn't allow registering
callCredentials on insecure connections.
OptionalchannelGRPC Channel arguments
option descriptions here
By default the SDK sets the following keepalive arguments:
grpc.keepalive_permit_without_calls: 1
grpc.keepalive_time_ms: 30_000
grpc.keepalive_timeout_ms: 15_000
To opt-out of keepalive, override these keys with undefined.
OptionalconnectMilliseconds to wait until establishing a connection with the server.
Used either when connecting eagerly with Connection.connect or calling Connection.ensureConnected.
number of milliseconds or ms-formatted string
OptionalcredentialsgRPC channel credentials.
ChannelCredentials are things like SSL credentials that can be used to secure a connection.
There may be only one ChannelCredentials. They can be created using some of the factory
methods defined here
Specifying a prebuilt ChannelCredentials should only be required for advanced use cases.
For simple TLS use cases, using the tls property is recommended. To register
CallCredentials (eg. metadata-based authentication), use the callCredentials property.
Either tls or this may be specified for configuring TLS
OptionalinterceptorsgRPC interceptors which will be
applied to every RPC call performed by this connection. By default, an interceptor will be included which
automatically retries retryable errors. If you do not wish to perform automatic retries, set this to an empty list
(or a list with your own interceptors). If you want to add your own interceptors while keeping the default retry
behavior, add this to your list of interceptors: makeGrpcRetryInterceptor(defaultGrpcRetryOptions()). See:
OptionalmetadataOptional mapping of gRPC metadata (HTTP headers) to send with each request to the server.
Setting the Authorization header is mutually exclusive with the apiKey option.
In order to dynamically set metadata, use Connection.withMetadata
Optional ExperimentalpluginsList of plugins to register with the connection.
Plugins allow you to configure the connection options. Any plugins provided will also be passed to any client built from this connection.
Plugins is an experimental feature; APIs may change without notice.
OptionaltlsTLS configuration. Pass a falsy value to use a non-encrypted connection,
or true or {} to connect with TLS without any customization.
For advanced scenario, a prebuilt grpc.ChannelCredentials object may instead be specified using the credentials property.
Either credentials or this may be specified for configuring TLS
gRPC and Temporal Server connection options
