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 🙏

@mallocbaal/agent-framework

v1.0.3

Published

TypeScript event-driven agent framework with RabbitMQ and saga logging (analog of Go agent-framework)

Readme

@mallocbaal/agent-framework (TypeScript)

TypeScript-библиотека с функционалом, аналогичным Go agent-framework: event-driven агенты с RabbitMQ и saga-логированием.

Требования: Node.js >= 20

Установка

npm install @mallocbaal/agent-framework
# или из монорепо
pnpm add @mallocbaal/agent-framework

Быстрый старт

import { loadConfig, App, type EventHandler, type Event } from '@mallocbaal/agent-framework';

class MyAgent implements EventHandler {
  async handle(_ctx: AbortSignal | undefined, event: Event): Promise<void> {
    switch (event.eventType) {
      case 'CLI_FLOW_INIT':
        return this.handleInit(event);
      case 'CLI_FLOW_CONTINUE':
        return this.handleContinue(event);
      case 'CLI_FLOW_END':
        return;
    }
  }

  private async handleInit(_event: Event): Promise<void> {
    // инициализация диалога
  }

  private async handleContinue(_event: Event): Promise<void> {
    // обработка сообщения или action
  }
}

async function main() {
  const config = loadConfig();
  const handler = new MyAgent();
  const app = await App.create({ config, handler });
  await app.run(); // до Ctrl+C или abort
}
main().catch(console.error);

Структура (аналог Go)

| Модуль | Назначение | |---------------|-------------------------------------| | events | Типы событий CLI_FLOW_* | | config | Загрузка конфигурации из env | | dispatcher | Маршрутизация INIT/CONTINUE/END | | rabbitmq | Consumer с retry | | saga | SagaLogger, MinIO, типы событий саги| | communicator| Клиент Communicator (GraphQL) | | pipeline | Processing + PostProcessing stages | | app | Жизненный цикл, health, bot register|

Конфигурация (env)

  • PORT — порт health (по умолчанию 8091)
  • COMMUNICATOR_URL — URL сервиса communicator
  • RABBITMQ_URL, RABBITMQ_EXCHANGE, RABBITMQ_QUEUE, RABBITMQ_BINDINGS, RABBITMQ_PREFETCH, RABBITMQ_MAX_RETRIES
  • MINIO_ENDPOINT, MINIO_ACCESS_KEY, MINIO_SECRET_KEY, MINIO_BUCKET, MINIO_USE_SSL
  • BOT_KEY, BOT_NAME, BOT_EVENT_STREAM, BOT_STREAMING_ENABLED

EventProcessor + Dispatcher

Вместо одного EventHandler можно реализовать EventProcessor и обернуть в Dispatcher:

import { Dispatcher, type EventProcessor, type Event } from '@mallocbaal/agent-framework';

class MyProcessor implements EventProcessor {
  async handleInit(_ctx, ev: Event) { /* ... */ }
  async handleContinue(_ctx, ev: Event) { /* ... */ }
}

const processor = new MyProcessor();
const dispatcher = new Dispatcher(processor);
const app = await App.create({ config, handler: dispatcher });

Pipeline

Использование паттерна Processing → Communicator → PostProcessing:

import {
  Pipeline,
  createProcessingFunc,
  createPostProcessingFunc,
  createCommunicatorClient,
  loadConfig,
  App,
  type ProcessingStage,
  type PostProcessingStage,
  type Event,
} from '@mallocbaal/agent-framework';

class MyStage implements ProcessingStage, PostProcessingStage {
  async processInit(_, ev) {
    return { contents: [{ type: 'text', order: 0, data: { text: 'Hello!' } }] };
  }
  async processContinue(_, ev) {
    return { contents: [{ type: 'text', order: 0, data: { text: 'You said: ' + (ev.message ?? '') } }] };
  }
  async postProcessInit() {}
  async postProcessContinue() {}
}

const config = loadConfig();
const comm = createCommunicatorClient(config.communicator.baseURL);
const pipeline = new Pipeline(comm, {
  processing: createProcessingFunc(new MyStage()),
  postProcessing: createPostProcessingFunc(new MyStage()),
}, 'my-agent');
const app = await App.create({ config, handler: pipeline });
await app.run();

Health

  • GET /healthz — 200 OK
  • GET /readyz — 200 если RabbitMQ доступен, иначе 503
