workflow-manager client
Kind: Exported class
new WorkflowManager(options)
Create a new client object.
| Param | Type | Default | Description | | --- | --- | --- | --- | | options | Object | | Options for constructing a client object. | | [options.address] | string | | URL where the server is located. Must provide this or the discovery argument | | [options.discovery] | bool | | Use clever-discovery to locate the server. Must provide this or the address argument | | [options.timeout] | number | | The timeout to use for all client requests, in milliseconds. This can be overridden on a per-request basis. Default is 5000ms. | | [options.keepalive] | bool | | Set keepalive to true for client requests. This sets the forever: true attribute in request. Defaults to true. | | [options.retryPolicy] | RetryPolicies | RetryPolicies.Single | The logic to determine which requests to retry, as well as how many times to retry. | | [options.logger] | module:kayvee.Logger | logger.New("workflow-manager-wagclient") | The Kayvee logger to use in the client. | | [options.circuit] | Object | | Options for constructing the client's circuit breaker. | | [options.circuit.forceClosed] | bool | | When set to true the circuit will always be closed. Default: true. | | [options.circuit.maxConcurrentRequests] | number | | the maximum number of concurrent requests the client can make at the same time. Default: 100. | | [options.circuit.requestVolumeThreshold] | number | | The minimum number of requests needed before a circuit can be tripped due to health. Default: 20. | | [options.circuit.sleepWindow] | number | | how long, in milliseconds, to wait after a circuit opens before testing for recovery. Default: 5000. | | [options.circuit.errorPercentThreshold] | number | | the threshold to place on the rolling error rate. Once the error rate exceeds this percentage, the circuit opens. Default: 90. |
