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 🙏

ai-dialog-plugin

v0.2.1

Published

A Vue 3 + TypeScript AI streaming dialog component.

Readme

ai-dialog-plugin

Vue 3 + TypeScript + Element Plus AI 流式对话组件。

组件不内置弹窗和外框盒子,外层容器由业务自己决定;但消息内容的渲染方式由组件内部固定处理:

| 能力 | 说明 | |---|---| | API 请求 | 通过 api 配置发起请求 | | 流式解析 | 读取 ReadableStream,解析普通文本流、SSE、常见 JSON delta | | 打字机展示 | 将解析后的内容逐字追加到 assistant 消息 | | 固定内容渲染 | assistant 消息在组件内部统一使用 markstream-vue 渲染 Markdown / 代码块等格式 | | 流程图渲染 | 内部集成 mermaid >= 11,支持 Mermaid 流程图 | | 外框自定义 | 用户只负责外部盒子、页面布局和样式 |

安装

npm install ai-dialog-plugin

宿主项目需要同时安装并注册 vueelement-plus

全局注册

import { createApp } from 'vue';
import ElementPlus from 'element-plus';
import 'element-plus/dist/index.css';
import AiDialogPlugin from 'ai-dialog-plugin';
import App from './App.vue';

createApp(App).use(ElementPlus).use(AiDialogPlugin).mount('#app');

使用方式

<script setup lang="ts">
import { AiStream, type AiDialogApiConfig } from 'ai-dialog-plugin';
import 'ai-dialog-plugin/style.css';

const api: AiDialogApiConfig = {
  url: '/api/chat',
  headers: {
    Authorization: 'Bearer your-token'
  },
  body: ({ text, messages }) => ({
    model: 'your-model',
    stream: true,
    messages: messages.map((message) => ({
      role: message.role,
      content: message.content
    }))
  })
};
</script>

<template>
  <section class="your-chat-box">
    <AiStream :api="api" :type-speed="24" />
  </section>
</template>

组件会自动完成请求发送、流式数据解析、消息追加、Markdown 渲染和打字机展示。业务侧只需要决定把 AiStream 放在弹窗、抽屉、页面卡片还是任意自定义盒子里。

Mermaid 示例:

```mermaid
flowchart TD
  A[插件接入] --> B[配置 API]
  B --> C[流式解析]
  C --> D[Markdown / Mermaid 渲染]
```
