Sequential Workflow Machine

Sequential Workflow Machine is a workflow execution engine for frontend and backend JavaScript applications.

It runs workflow definitions step by step, supports pluggable execution handlers, and uses the same data model as Sequential Workflow Designer.

Why Use This Workflow Engine​

  • Execute process automation logic in your own runtime.
  • Run sequential task pipelines in backend jobs.
  • Implement custom business workflows with predictable execution flow.
  • Move from visual workflow design to production runtime using one definition model.

Key Capabilities​

  • sequential workflow execution
  • custom step handlers (activities)
  • frontend and backend runtime support
  • TypeScript-friendly API
  • shared workflow definition model with the Designer

Execution Model​

The engine executes steps in order and delegates step behavior to your handlers.

import { createAtomActivity } from 'sequential-workflow-machine';

const activity = createAtomActivity('sendEmail', {
  handler: async (step, globalState) => {
    // custom execution logic
  },
});

Quick Start​

npm install sequential-workflow-model sequential-workflow-machine
