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 🙏

使用示例

基本聊天界面(带 SSE 支持)

import React from "react";
import { ChatInterface } from "lan-chat-interface";
import "lan-chat-interface/styles.css";

const App: React.FC = () => {
  return (
    <div className="h-screen w-full">
      <ChatInterface
        apiRoute="https://your-sse-endpoint.com/chat"
        method="POST"
        title="AI 聊天助手"
        initialMessage="你好,我是 AI 助手,有什么可以帮你?"
      />
    </div>
  );
};

export default App;

带历史记录的聊天界面

import React from "react";
import { ChatInterface } from "lan-chat-interface";
import "lan-chat-interface/styles.css";
import { Message } from "lan-chat-interface/types";

const App: React.FC = () => {
  // 历史消息记录
  const initialHistory: Message[] = [
    {
      id: "1",
      role: "user",
      content: "你好,介绍一下自己",
    },
    {
      id: "2",
      role: "assistant",
      content: "你好!我是一个基于人工智能的聊天助手,很高兴为您服务。",
    },
  ];

  return (
    <div className="h-screen w-full">
      <ChatInterface
        apiRoute="https://your-sse-endpoint.com/chat"
        title="AI 聊天助手"
        initialHistory={initialHistory}
      />
    </div>
  );
};

export default App;

使用自定义请求体构建函数

import React from "react";
import { ChatInterface } from "lan-chat-interface";
import "lan-chat-interface/styles.css";
import { BodyBuilderFn } from "lan-chat-interface/types";

const App: React.FC = () => {
  // 自定义请求体构建函数
  const customBodyBuilder: BodyBuilderFn = (payload) => {
    return {
      prompt: payload.currentMessage,
      conversation_history: payload.history.map((msg) => ({
        role: msg.role,
        content: msg.content,
      })),
      temperature: 0.7,
      max_tokens: 500,
    };
  };

  return (
    <div className="h-screen w-full">
      <ChatInterface
        apiRoute="https://your-sse-endpoint.com/chat"
        method="POST"
        title="AI 聊天助手"
        initialMessage="你好,我是 AI 助手,有什么可以帮你?"
        bodyBuilder={customBodyBuilder}
      />
    </div>
  );
};

export default App;

使用自定义头像、名称和占位符

import React from "react";
import { ChatInterface } from "lan-chat-interface";
import "lan-chat-interface/styles.css";

const App: React.FC = () => {
  return (
    <div className="h-screen w-full">
      <ChatInterface
        apiRoute="https://your-sse-endpoint.com/chat"
        method="POST"
        title="我的专属 AI 助手"
        initialMessage="你好,我是你的专属 AI 助手,有什么可以帮你?"
        userAvatar="https://example.com/user-avatar.png"
        aiAvatar="https://example.com/ai-avatar.png"
        userName="用户"
        aiName="AI 助手"
        placeholder="请输入您的问题..."
      />
    </div>
  );
};

export default App;

使用禁用状态

import React, { useState } from "react";
import { ChatInterface } from "lan-chat-interface";
import "lan-chat-interface/styles.css";

const App: React.FC = () => {
  const [isDisabled, setIsDisabled] = useState(false);

  return (
    <div className="h-screen w-full">
      <div className="p-4 bg-gray-100">
        <button
          onClick={() => setIsDisabled(!isDisabled)}
          className="px-4 py-2 bg-blue-500 text-white rounded"
        >
          {isDisabled ? "启用输入" : "禁用输入"}
        </button>
      </div>
      <ChatInterface
        apiRoute="https://your-sse-endpoint.com/chat"
        method="POST"
        title="AI 聊天助手"
        initialMessage="你好,我是 AI 助手,有什么可以帮你?"
        disabled={isDisabled}
      />
    </div>
