Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

@kedge-agentic/workflow

v0.1.0

Published

Framework-free workflow engine for ccaas. Cascade context, trigger registry, engine + state-change pipeline + types. Pairs with @kedge-agentic/workflow-nest (NestJS adapter) and @kedge-agentic/workflow-client (HTTP client) to form a three-sibling family.

Readme

@kedge-agentic/workflow

ccaas 的框架无关 workflow 引擎 — cascade 上下文、trigger 注册表、dispatch pipeline。

类型: 框架无关库 · 状态: public · v0.1.0

用途

@kedge-agentic/ontology 上的声明式 trigger 层。 Solution 注册 TriggerDef 对象 (when 谓词 + then action),引擎路由事件到匹配的 action。 灵感来自 Palantir Carbon。

零 NestJS 耦合 — 配套三件套:

宿主应用注册 DI port (MANIFEST_ACCESSOR_PORT, INDICATOR_REGISTRY_PORT) 并通过 factory provider 实例化引擎; 经典接线见 workflow-nest 的 WorkflowModule

主要导出

import {
  WorkflowEngine,
  WorkflowRegistry,
  TriggerDef,
  TriggerFireInput,
  currentCascade,
  withRootCascade,
  withChildCascade,
} from '@kedge-agentic/workflow'

// 给 DI 宿主用的 port token
import {
  MANIFEST_ACCESSOR_PORT,
  INDICATOR_REGISTRY_PORT,
} from '@kedge-agentic/workflow/ports'

用法

const CHAT_TURN_TRIGGER: TriggerDef = {
  apiName: 'on_chat_turn_classify',
  manifest: 'LessonSession',
  kind: 'event',
  watch: { stream: 'events' },
  when: (input) => input.event?.payload?.type === 'chat_turn',
  then: {
    action: 'workflow-actions-chat-turn.classify_chat_turn_indicators',
    args: (input) => ({ entityId: input.event.payload.studentId }),
    as: 'admin',
  },
}

registry.registerTrigger(CHAT_TURN_TRIGGER)
await engine.ingestEvent({ sessionId, payload: { type: 'chat_turn', ... } })

依赖

  • 运行时: @kedge-agentic/ontology
  • 无 peerDeps,无框架耦合
