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 🙏

npm-version size license

基于 Vue3+ts 的弹幕交互组件

Demo: https://dshuais.github.io/danmaku-vue/

Install

$ npm install danmaku-vue --save
或
$ pnpm add danmaku-vue --save

Usage

<script setup>
import Danmaku from 'danmaku-vue'

const danmus = ref(['danmu1', 'danmu2', 'danmu3', '...'])
</script>

<template>
  <Danmaku :danmus="danmus" style="height:100px; width:300px;"></Danmaku>
</template>

Attributes

| 参数 | 说明 | 类型 | 可选值 | 默认值 | | :------------: | :--------------------------------------------------: | :-----: | :--------------: | :----: | | danmus | 弹幕元素列表,支持纯文本或者自定义对象(支持 v-model) | Array | 字符串[]或对象[] | 必填 | | channels | 轨道数量 | Number | | 0 | | autoplay | 是否自动播放 | Boolean | | true | | useSlot | 是否开启弹幕插槽 | Boolean | | false | | useSuspendSlot | 是否开启弹幕悬浮时插槽(开启isSuspend时可用) | Boolean | | false | | loop | 是否开启弹幕循环 | Boolean | | false | | fontSize | 弹幕字号(slot 模式下不可用) | Number | | 18 | | extraStyle | 额外样式(slot 模式下不可用) | String | | - | | speeds | 弹幕速度(每秒移动的像素数) | Number | | 100 | | debounce | 弹幕刷新频率(ms) | Number | | 100 | | randomChannel | 随机选择轨道插入 | Boolean | | false | | isSuspend | 是否开启弹幕悬浮暂停 | Boolean | | false | | top | 弹幕垂直间距(px) | Number | | 10 | | right | 弹幕水平间距(px) | Number | | 10 |

  • 注 1:channels 为 0,则轨道数为容器可容纳最多轨道数(整个容器)
  • 注 2:danmus 初始化后如果为空,则 autoplay 失效。因此对于异步加载的弹幕数据,需要手动调用 refName.value.play() 进行播放
  • 注 3:弹幕刷新频率为每隔多长时间插入一条弹幕

内置方法

通过以下方式调用:

import Danmaku from 'danmaku-vue'
const danmakuRef = ref<InstanceType<typeof Danmaku>>(null)
danmakuRef.value.play()
...

<Danmaku ref="danmakuRef"></Danmaku>

| 方法名 | 说明 | 参数 | | :-----------: | :------------------------------------------: | :----------------------------: | | play | 开始/继续播放 | - | | pause | 暂停弹幕播放 | - | | clear | 停止播放并清空弹幕 | - | | show | 弹幕显示 | - | | hide | 弹幕隐藏 | - | | reset | 重置配置(也可在改变播放区域大小后调用) | - | | resize | 容器尺寸改变时重新计算滚动距离(需手动调用) | - | | push | 发送弹幕(插入到弹幕列表末尾,排队显示) | danmu 数据,可以是字符串或对象 | | add | 发送弹幕(插入到当前播放位置,实时显示) | danmu 数据,可以是字符串或对象 | | insert | 绘制弹幕(实时插入,不进行数据绑定) | danmu 数据,可以是字符串或对象 | | getPlayState | 获得当前播放状态 | - | | getInsertList | 获取使用 insert 方法插入的弹幕列表 | danmu[] |

  • 注 1:pushadd 的返回值为插入后的下标,可通过判断下标的方式对当前插入弹幕进行样式定制
  • 注 2:insertpush/add 的区别在于,insert 不进行数据绑定,而是直接插入 DOM,适用于直播等场景
  • 注 3:推荐使用 insert 方式单条插入弹幕,因为add会进行数据绑定

Events

| 事件名 | 说明 | 返回值 | | :------: | :----------------------------: | :-------------------------: | | list-end | 所有弹幕插入完毕 | - | | play-end | 所有弹幕播放完成(已滚出屏幕) | index(最后一个弹幕的下标) | | dm-click | 弹幕点击 | danmu数据,index |

Slot

如果你有自定义弹幕结构与样式的需求,你可以传入任意结构的对象并自己写内部样式。

| name | 说明 | 回调参数 | | :-----: | :------------------------------------------: | :----------: | | default | 默认slot | - | | dm | 自定义弹幕样式(需useSlot为true) | danmu,index | | suspend | 自定义弹幕悬浮样式(需useSuspendSlot为true) | danmu,index |

<script setup>
import Danmaku from 'danmaku-vue'

const danmus = ref([{ avatar: 'http://a.com/a.jpg', text: 'aaa' }...])}
</script>

<template>
  <Danmaku ref="danmaku" :danmus="danmus" useSlot useSuspendSlot loop :channels="5">
    <template #dm="{ danmu, index }">
      <div class="danmu-item">
          <img class="danmu-item--avatar" v-if="danmu.avatar" :src="danmu.avatar" alt="">
          <div>{{ danmu.text }}</div>
      </div>
    </template>
    <template #suspend="{ danmu, index }">
      <div class="danmu-suspend">
        <div class="item" @click="handleAdd(danmu)">➕</div>
        <div class="item" @click="handleIndex(index)">👍</div>
      </div>
    </template>
  </Danmaku>
</template>
  • 注 1:dm slotsuspend slot同时使用时,可通过dm-item:hover设置悬浮后样式

  • 注 2:suspend slot的背景色默认为transparent,可通过!importantdm-suspend强制更改悬浮后背景
