Preface

As we all know, NodeJS, as a back-end development language and operating environment, is good in everything but one NodeJS工作流引擎. CabloyJS 4.0 has been developed with emphasis NodeJS工作流引擎, and as a built-in basic core module, it has further expanded the application scenarios of NodeJS in the back-end, providing basic support for the in-depth research and development of various business business logics

Features of NodeJS workflow engine

1. Easier configuration: adopt the configuration JSONfor process definition, bid farewell to the redundancy of XML configuration files
2. Process definition: support historical version, support enable/disable
3. Clearer architecture: 3.core modules are used to implement the architecture of the workflow engine with a layered mechanism, so that the workflow is no longer mysterious, and the source code no longer overlaps.

1. Support 业务流程and审批流程
2. And Atom三生三世combined, built a set of Atom-based 审批工作流. See: Atomic Phase (Sansheng III)
3. And 表单验证combination of support nodes are arranged in different processes 读取字段权限and 修改字段权限. See: form validation
4. AOPWorkflow logic can be customized by mechanism
5. ListenerWorkflow logic can be customized by mechanism
6. Open architecture supports more 流程节点customized development
7. Contains a lot of 测试驱动code, you can quickly get started using workflow

Workflow demo

1. Create a new draft:采购订单
2. Select the one you want to use 流程定义, then submit it, and enter the draft into the corresponding审批流程
3. Sign for the task and process the task
4. The process is over and the draft is converted to归档

A minimal workflow definition

src/module/test-flow/backend/src/config/static/flowDef/set00_simple.js

  {
    listener: null,
    process: {
      nodes: [
        {
          id:'startEvent_1',
          name:'Start',
          type:'startEventNone',
        },
        {
          id:'endEvent_1',
          name:'End',
          type:'endEventNone',
        },
      ],
      edges: [
        {
          id:'edge_1',
          source:'startEvent_1',
          target:'endEvent_1',
        },
      ],
    },
  }

An approval process definition

src/module/test-flow/backend/src/config/static/flowDef/set01_atomUserTask.js

  {
    listener: null,
    process: {
      nodes: [
        {
          id:'startEvent_1',
          name:'Drafting',
          type:'startEventAtom',
          options: {
            atom: {
              module: moduleInfo.relativeName,
              atomClassName:'purchaseOrder',
            },
            conditionExpression:'atom._flowDefKey===\'set01_atomUserTask\'',
          },
        },
        {
          id:'activity_1',
          name:'Review',
          type:'activityUserTask',
          options: {
            assignees: {
             //users: '1,2',
             //roles: '1,2',
              vars:'flowUser',
            },
            confirmation: false,
            bidding: false,
            completionCondition: {
             //passed: 1,
             //rejected: '100%',
            },
           //rejectedNode:null,
           //allowRejectTask: true,
           //allowCancelFlow: false,
            schema: {
              write: [
                'atomName',
                {
                  name:'description',
                  property: {
                    type:'string',
                    ebType:'text',
                    ebTitle:'Description',
                  },
                },
              ],
            },
          },
        },
        {
          id:'endEvent_1',
          name:'End',
          type:'endEventNone',
        },
      ],
      edges: [
        {
          id:'edge_1',
          source:'startEvent_1',
          target:'activity_1',
        },
        {
          id:'edge_2',
          source:'activity_1',
          target:'endEvent_1',
        },
      ],
    },
  }
