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 🙏

Core AI provider abstraction, tools, and knowledge base for ChatCops

Readme

@chatcops/core

Core AI provider abstraction, tools, knowledge base, conversation management, analytics, and i18n for ChatCops.

Install

npm install @chatcops/core

Providers

Unified interface for Claude, OpenAI, and Gemini. Supports streaming (AsyncGenerator) and sync modes.

import { createProvider } from '@chatcops/core';

const provider = await createProvider({
  type: 'claude',       // 'claude' | 'openai' | 'gemini'
  apiKey: process.env.ANTHROPIC_API_KEY,
  model: 'claude-haiku-4-5-20251001', // optional
});

// Streaming
for await (const chunk of provider.chat({
  messages: [{ id: '1', role: 'user', content: 'Hello', timestamp: Date.now() }],
  systemPrompt: 'You are a helpful assistant.',
})) {
  process.stdout.write(chunk);
}

// Sync
const response = await provider.chatSync({
  messages: [{ id: '1', role: 'user', content: 'Hello', timestamp: Date.now() }],
  systemPrompt: 'You are a helpful assistant.',
});

Default models: claude-haiku-4-5-20251001 (Claude), gpt-4o-mini (OpenAI), gemini-2.0-flash (Gemini).

Tools

Define tools the AI can call. Built-in LeadCaptureTool for collecting contact info.

import { LeadCaptureTool } from '@chatcops/core';

const leadTool = new LeadCaptureTool((lead) => {
  console.log('Lead captured:', lead.name, lead.email);
});

Custom tools implement the ChatTool interface:

import type { ChatTool, ToolResult } from '@chatcops/core';

const myTool: ChatTool = {
  name: 'lookup_order',
  description: 'Look up an order by ID',
  parameters: {
    orderId: { type: 'string', description: 'The order ID' },
  },
  required: ['orderId'],
  async execute(input): Promise<ToolResult> {
    return { success: true, data: { status: 'shipped' } };
  },
};

Knowledge Base

Feed context to the AI with text chunks or FAQ pairs.

import { TextKnowledgeSource, FAQKnowledgeSource } from '@chatcops/core';

const text = new TextKnowledgeSource([
  'ChatCops supports Claude, OpenAI, and Gemini.',
  'The widget is zero-dependency and uses Shadow DOM.',
]);

const faq = new FAQKnowledgeSource([
  { question: 'What is ChatCops?', answer: 'An embeddable AI chat widget.' },
  { question: 'Is it free?', answer: 'Yes, MIT licensed.' },
]);

const context = await faq.getContext('is chatcops free');

Conversation Management

import { ConversationManager } from '@chatcops/core';

const manager = new ConversationManager({ maxMessages: 100 });
const conversation = await manager.getOrCreate('conv-123');
await manager.addMessage('conv-123', {
  id: '1', role: 'user', content: 'Hello', timestamp: Date.now(),
});

Plug in your own store by implementing ConversationStore.

Analytics

import { AnalyticsCollector } from '@chatcops/core';

const analytics = new AnalyticsCollector();
analytics.track('message:sent', { conversationId: 'conv-123' });
const stats = analytics.getStats();

i18n

8 built-in locales: en, es, hi, fr, de, ja, zh, ar.

import { getLocale, getAvailableLocales } from '@chatcops/core';

const strings = getLocale('es');
console.log(strings.welcomeMessage); // "Hola! Como puedo ayudarte hoy?"
console.log(getAvailableLocales());  // ['en', 'es', 'hi', 'fr', 'de', 'ja', 'zh', 'ar']
