用js实现已经画好的工作流

npm install workflow-engine-js

const WorkflowEngine = require('workflow-engine-js');

// 定义流程
const myWorkflow = {
  name: 'MyWorkflow',
  nodes: [
    {
      id: 'start',
      type: 'start',
      next: ['task1']
    },
    {
      id: 'task1',
      type: 'task',
      task: async () => {
        console.log('Executing Task 1');
        return true;
      },
      next: ['task2']
    },
    {
      id: 'task2',
      type: 'task',
      task: async () => {
        console.log('Executing Task 2');
        return true;
      },
      next: ['end']
    },
    {
      id: 'end',
      type: 'end'
    }
  ]
};

// 创建工作流引擎实例
const engine = new WorkflowEngine();

// 启动工作流
engine.start(myWorkflow).then(() => {
  console.log('Workflow completed successfully');
}).catch((error) => {
  console.error('Workflow failed:', error);
});
