WorkflowGraphRoute

CORE · interface · 类型合同

Declaration order is retained even when multiple routes share a topology edge.

导入

TypeScript

import type { WorkflowGraphRoute } from '@jangts/agent-core/engine';

JavaScript

/** @typedef {import('@jangts/agent-core/engine').WorkflowGraphRoute} WorkflowGraphRoute */

定义

字段结构

字段	类型	必需	说明
order	number	必需	只读。见类型定义及调用场景。
routeId	string | undefined	可省略	只读。见类型定义及调用场景。
description	string | undefined	可省略	只读。见类型定义及调用场景。
conditional	boolean	必需	只读。见类型定义及调用场景。
conditionId	string | undefined	可省略	只读。见类型定义及调用场景。
edgeId	string	必需	只读。见类型定义及调用场景。

使用示例

• Workflow：节点、路由与局部状态更新：用一份真实参与运行的节点定义，集中展示执行顺序、分支、错误去向和结束条件。
• 复用基础 Workflow 与 Agent 分支：add 保留旧 Workflow，生成组合后的新 Workflow；fork 继承已有绑定及分支来源。

一个节点完成问候

入门 · Node.js

TypeScript

import { AgentCoreEngine, defineWorkflow, route } from '@jangts/agent-core/engine';

type State = { name: string; answer?: string };
const workflow = defineWorkflow<State, string>({
  id: 'greeting',
  nodes: [{
    id: 'greet', description: '根据本次姓名生成问候', startsRound: true,
    run: state => ({ answer: '你好，' + state.name }),
    routes: [route.deliver('answer')],
  }],
});
console.log(workflow.entryNodeId);
console.log(workflow.describe());

JavaScript

import { AgentCoreEngine, defineWorkflow, route } from '@jangts/agent-core/engine';
const workflow = defineWorkflow({
    id: 'greeting',
    nodes: [{
            id: 'greet', description: '根据本次姓名生成问候', startsRound: true,
            run: state => ({ answer: '你好，' + state.name }),
            routes: [route.deliver('answer')],
        }],
});
console.log(workflow.entryNodeId);
console.log(workflow.describe());

增加校验阶段，原状态与 run 方式不变

配置 · Node.js

TypeScript

import { AgentCoreEngine, defineWorkflow, route } from '@jangts/agent-core/engine';
type State = { name: string; answer?: string; error?: string };
const workflow = defineWorkflow<State, string>({
  id: 'greeting',
  nodes: [
    { id: 'check', description: '检查姓名', startsRound: true,
      run: state => ({ error: state.name.trim() ? undefined : '姓名不能为空' }),
      routes: [route.toIfError('failure'), route.to('greet')] },
    { id: 'greet', description: '生成问候', provides: ['answer'],
      run: state => ({ answer: '你好，' + state.name }), routes: [route.deliver('answer')] },
    { id: 'failure', description: '返回校验提示', requires: ['error'], routes: [route.deliver('error')] },
  ],
});
console.log(await new AgentCoreEngine({ workflow }).run({ name: 'Ivan' }));

JavaScript

import { AgentCoreEngine, defineWorkflow, route } from '@jangts/agent-core/engine';
const workflow = defineWorkflow({
    id: 'greeting',
    nodes: [
        { id: 'check', description: '检查姓名', startsRound: true,
            run: state => ({ error: state.name.trim() ? undefined : '姓名不能为空' }),
            routes: [route.toIfError('failure'), route.to('greet')] },
        { id: 'greet', description: '生成问候', provides: ['answer'],
            run: state => ({ answer: '你好，' + state.name }), routes: [route.deliver('answer')] },
        { id: 'failure', description: '返回校验提示', requires: ['error'], routes: [route.deliver('error')] },
    ],
});
console.log(await new AgentCoreEngine({ workflow }).run({ name: 'Ivan' }));
