    Constructors

    (constructor)(opts, gaxInstance)

      constructor 
 ( 
 opts 
 ?: 
  
 ClientOptions 
 , 
  
 gaxInstance 
 ?: 
  
 typeof 
  
 gax 
  
 | 
  
 typeof 
  
 gax 
 . 
 fallback 
 );

    Construct an instance of WorkflowsClient.

    Parameters
    Name
    Description
    opts
    ClientOptions
    gaxInstance
    typeof gax | typeof fallback

    : loaded instance of google-gax . Useful if you need to avoid loading the default gRPC version and want to use the fallback HTTP implementation. Load only fallback version and pass it to the constructor: ``` const gax = require('google-gax/build/src/fallback'); // avoids loading google-gax with gRPC const client = new WorkflowsClient({fallback: true}, gax); ```
