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 🙏

Readme

GoViewWorker

GoViewWorker 是基于 GoView 低代码平台封装的前端组件库。它允许开发者将 GoView 的核心功能(设计器、渲染器、配置器)作为一个模块集成到现有的项目中,并支持宿主项目动态注册自定义组件。

安装

pnpm add go-view-worker
# 或
npm install go-view-worker

需要前置安装的依赖

'vue' 'naive-ui' 'pinia' 'vue-router'

快速开始

1. 引入样式与初始化

在项目的入口文件(如 main.tsbootstrap.ts)中进行初始化:

import { createApp } from 'vue'
import App from './App.vue'

// 1. 引入样式
import 'go-view-worker/dist/style.css'
// 2. 引入初始化函数
import { initGoViewWorker } from 'go-view-worker/init'

const app = createApp(App)

// 3. 安装插件
initGoViewWorker(app)

app.mount('#app')

2. 在宿主项目中配置 (Before Mount)

在挂载应用或使用组件之前,需要通过 useGlobalConfigStore 进行配置初始化。这一步通常封装在一个 Hook 中(例如 useGoViewInit),用于加载宿主项目的自定义组件、图片资源及配置项。

import { useGlobalConfigStore } from 'go-view-worker'
import { markRaw } from 'vue'

// 假设你有自己的组件库定义
import { MyChartList } from '@/packages/components/Charts/index'

export function useGoViewInit() {
  const globalConfigStore = useGlobalConfigStore()

  // 使用 Vite 的 glob 导入功能自动加载宿主项目的组件文件,告诉go-view-worker去哪里找资源
  //config.vue的相对路径
  const configModules = import.meta.glob('../packages/components/**/config.vue', { eager: true })
  //index.vue的相对路径
  const indexModules = import.meta.glob('../packages/components/**/index.vue', { eager: true })
  //config.ts的相对路径
  const configTsModules = import.meta.glob('../packages/components/**/config.ts', { eager: true })
  //图片的相对路径
  const imagesModules = import.meta.glob('../assets/img/**', { eager: true })

  globalConfigStore.initConfig({
    // 1. 编辑器左侧菜单配置
    menuOptions: [
      {
        key: 'Charts',
        label: '我的图表',
        list: MyChartList
      }
    ],
    // 2. 注入模块 (关键:让 Worker 能找到宿主组件)
    configModules, // 配置面板组件 (.vue)
    indexModules, // 视图展示组件 (.vue)
    configTsModules, // 组件配置文件 (.ts)
    imagesModules, // 图片资源

    // 3. 配置组件列表 (用于注册)
    chartsList: markRaw(MyChartList),

    // 4. 主题配置
    theme: {
      darkMode: false,
      primaryColor: '#1677ff'
    },

    // 5. 文件上传方法 (可选,用于支持编辑器内的图片上传)
    uploadFile: async (file: File) => {
      // 实现你的上传逻辑,返回图片 URL
      const formData = new FormData()
      formData.append('file', file)
      const res = await uploadApi(formData)
      return res.url
    }
  })
}

3. 使用组件

在 Vue 页面中直接使用导出的核心组件:

设计器 (Designer)

用于编辑和构建可视化大屏。

<template>
  <div style="height: 100vh">
    <Configurator>
      <Designer />
    </Configurator>
  </div>
</template>

<script setup lang="ts">
import { Designer, Configurator } from 'go-view-worker'
import { useGoViewInit } from './hooks/useGoViewInit'

// 确保先初始化配置
useGoViewInit()
</script>

渲染器 (Renderer)

用于根据 JSON 配置渲染最终页面。

<template>
  <div style="height: 100vh">
    <Renderer :data="chartData" />
  </div>
</template>

<script setup lang="ts">
import { Renderer } from 'go-view-worker';
// chartData 通常是设计器保存出来的 JSON 对象
const chartData = { ... };
</script>

自定义组件开发规范

如果你需要在宿主项目中开发组件并注册到 GoViewWorker,请遵循以下目录结构:

/packages/components
  /Charts
    /MyBarChart
      /index.vue      (展示组件)
      /config.vue     (右侧属性配置面板组件)
      /config.ts      (组件基础配置类)
      /index.ts       (导出配置元数据)

1. config.ts

组件配置类需继承基础配置类(建议在宿主项目封装一个 PublicConfigClass 或直接仿照标准结构),并定义默认属性。

// config.ts
import { PublicConfigClass } from '@/packages/public/baseConfig' // 宿主封装的基类
import { MyBarChartConfig } from './index'

export default class Config extends PublicConfigClass {
  public key = MyBarChartConfig.key
  public chartConfig = { ...MyBarChartConfig }

  // 自定义配置项
  public option = {
    color: 'red',
    fontSize: 20
  }

  // 必须:重写默认长宽和位置 (Override)
  public override attr = {
    x: 50,
    y: 50,
    w: 400, // 默认宽
    h: 300, // 默认高
    offsetX: 0,
    offsetY: 0,
    zIndex: -1
  }
}

2. index.ts

// index.ts
export const MyBarChartConfig = {
  key: 'MyBarChart', // 唯一标识
  chartKey: 'VMyBarChart', // 对应注册的 Vue 组件名 (View)
  conKey: 'VCMyBarChart', // 对应注册的配置组件名 (Config)
  title: '自定义柱状图',
  category: 'Charts',
  categoryName: '图表',
  package: 'Charts',
  image: 'preview.png'
}

核心 API

useGlobalConfigStore

  • initConfig(options): 初始化全局配置。
  • getChartsList: 获取注册的组件列表。
  • setItem(key, value): 设置全局状态。

组件

  • Designer: 画布设计器。
  • Renderer: 画布渲染器。
  • Configurator: 单独使用的配置面板(较少直接使用)。
