.after()

The .after() method defines explicit dependencies between workflow steps, enabling branching and merging paths in your workflow execution.

Usage​

Basic Branching​

workflow
  .step(stepA)
  .then(stepB)
  .after(stepA) // Create new branch after stepA completes
  .step(stepC);

Merging Multiple Branches​

workflow
  .step(stepA)
  .then(stepB)
  .step(stepC)
  .then(stepD)
  .after([stepB, stepD]) // Create a step that depends on multiple steps
  .step(stepE);

Parameters​

steps:

Step | Step[]
A single step or array of steps that must complete before continuing

Returns​

workflow:

LegacyWorkflow
The workflow instance for method chaining

Examples​

Single Dependency​

workflow
  .step(fetchData)
  .then(processData)
  .after(fetchData) // Branch after fetchData
  .step(logData);

Multiple Dependencies (Merging Branches)​

workflow
  .step(fetchUserData)
  .then(validateUserData)
  .step(fetchProductData)
  .then(validateProductData)
  .after([validateUserData, validateProductData]) // Wait for both validations to complete
  .step(processOrder);
