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 🙏

类组件+自动化的依赖注入(可选) = 极致的代码体验 DEMO

前提条件

需要reflect-metadata 的支持

pnpm add @abraham/reflection injection-js 

项目入口需要引入 reflect-metadata

import '@abraham/reflection'

tsconfig.json 需要增加配置:

{
  "compilerOptions": {
    "experimentalDecorators": true,
    "emitDecoratorMetadata": true,
    "useDefineForClassFields": false
  } 
}

安装

pnpm add vue3-oop 

vite配置

因为esbuild不支持装饰器的metadata属性,所以需要安装 @vue3-oop/plugin-vue-jsx 插件使用原始ts编译

定义组件

import { Autobind, ComponentProps, Computed, Hook, Link, Mut, VueComponent } from 'vue3-oop'
import { Directive, VNodeChild, watch } from 'vue'

interface FooProps {
  size: 'small' | 'large'
  // 组件的slots
  slots: {
    item(name: string): VNodeChild
  }
}

class Foo extends VueComponent<FooProps> {
  // vue需要的运行时属性检查
  static defaultProps: ComponentProps<FooProps> = ['size']

  constructor() {
    super()
    // watch在构造函数中初始化
    watch(
      () => this.count,
      () => {
        console.log(this.count)
      },
    )
  }

  // 组件自身状态
  @Mut() count = 1

  // 计算属性
  @Computed()
  get doubleCount() {
    return this.count * 2
  }

  add() {
    this.count++
  }

  // 自动绑定this
  @Autobind()
  remove() {
    this.count--
  }

  // 生命周期
  @Hook('Mounted')
  mount() {
    console.log('mounted')
  }

  // 对元素或组件的引用
  @Link() element?: HTMLDivElement

  render() {
    return (
      <div ref="element">
        <span>{this.props.size}</span>
        <button onClick={() => this.add()}>+</button>
        <span>{this.count}</span>
        <button onClick={this.remove}>-</button>
        <div>{this.context.slots.item?.('aaa')}</div>
        <input type="text" v-focus/>
      </div>
    )
  }
}

定义服务

组件和服务的差距是缺少了render这一个表现UI的函数,其他都基本一样

class CountService extends VueService {
  @Mut() count = 1
  add() {
    this.count++
  }
  remove() {
    this.count--
  }
}

依赖注入

Angular文档

import { VueComponent, VueService } from 'vue3-oop'
import { Injectable } from 'injection-js'

// 组件DI
@Component({
  providers: [CountService]
})
class Bar extends VueComponent {
  constructor(private countService: CountService) {super()}

  render() {
    return <div>{this.countService.count}</div>
  }
}

@Injectable()
class BarService extends VueService {
  constructor(private countService: CountService) {super()}
}
