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 🙏

Vdi

一个简单的 vue di 插件,基于@wendellhu/redi实现

破坏性更新

1.0版本删除了vue-module,overlay相关的api,如果你在使用vue-module overlay请继续留在0.5.0版本

安装

$ npm install @wendellhu/redi vdi

功能

  • 更好的依赖注入
    基于 redi 增强 vue3 依赖注入

  • 简单使用,非侵入
    最少两个 api 就可以完成强大的依赖注入

例子

简单使用

创建服务

// count.service.ts
import { ref } from 'vue'
export class CountService {
    count = ref<number>(0)
    inc() {
        this.count.value++
    }
}

页面注入并使用

<!--Father.vue -->
<script setup lang="ts">
import { onProvider, useDependency } from 'vdi'

import { CountService } from './count.service'

//在当前组件注入依赖
onProvider([[CountService]])

//获取提供的依赖,self为true时候获取的是当前组件的依赖
const countService = useDependency(CountService, { self: true })
</script>

<template>
    {{ countService.count }}
    <button @click="countService.inc">修改</button>
</template>

在子组件使用

<!--Child.vue -->
<script setup lang="ts">
import { onProvider, useDependency } from 'vdi'

import { CountService } from './count.service'

//获取提供的依赖,不需要使用self,因为父组件已经注入了依赖
const countService = useDependency(CountService)
</script>

<template>
    <div class="child">
        子组件: {{ countService.count }}
        <button @click="countService.inc">count+</button>
    </div>
</template>
