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 🙏

参数

字段名|类型|默认值|是否必填 --|--|--|-- marketInfo|Object|undefined|是

说明:这个参数用于说明交易对的信息,你应该传入一个类似这样的对象:

{
  zi: 'BTC', // 子币名称
  mu: 'USDT', // 母币名称
  ziPoint: 8, // 子币小数点精度
  muPoint: 4, // 母币小数点精度
}

字段名|类型|是否必填 --|--|-- options|Object|否

说明:自定义设置,你应该传入一个类似这样的对象:

{
  isFlash: false, // 当某个价位(ticks)的数量(lots)变化时,是否高亮闪烁一下;默认false
  isHoverInfo: true, // 当鼠标放在价位上时,是否显示均价浮窗;默认true
  hoverType: 'left' // 均价浮窗显示在左边(left)还是右边(right), 默认"left"
}

字段名|类型|默认值|是否必填 --|--|--|-- lastPrice|String/Number|''|否

说明:你可以传入一个最终成交的价格,这会显示在组件中间那个位置 比如这样:50000.1234

字段名|类型|默认值|是否必填 --|--|--|-- lastFormatFial|String|''|否

说明:你可以传入一个字符串,这会显示在组件中间那个位置,跟在lastPrice的后面 比如这样:"≈ 300000 RMB"

字段名|类型|默认值|是否必填 --|--|--|-- sourceData|Object|undefined|是

说明:这是交易挂单的原始数据,通常由websocket不停的推送最新数据,你应该传入这样的对象: (不要增量更新,每次有新数据都应该传入一个全新的sourceData对象)

{
  askData: [ // 卖方数据 正序倒序都无所谓,组件会帮你排序
    {ticks: '50001.2234', lots: '2.23456789'}
    {ticks: '50000.1234', lots: '1.23456789'},
    ...
  ],
  bidData: [ // 买方数据 正序倒序都无所谓,组件会帮你排序
    {ticks: '49999.1234', lots: '1.23456789'},
    {ticks: '49998.2234', lots: '2.23456789'}
  ]
}

事件

onAccuracyChange(p)

当深度发生变化时会触发一次 组件会根据当前数据(sourceData)计算出所有可能的深度选项,显示在右上角下拉框中 首次计算出深度时,组件会自动选中第1个深度选项,则会触发一次该事件 之后每次用户选择不同的深度时,才会再触发

返回值:

{"label":"0.01","value":"100"} 会返回一个类似这样的对象 label是组件中显示的数字 value是实际对应的值,1表示没有合并深度,10表示向前合并一位小数点,100表示合并两位小数点 以此类推

关于深度合并的解释

比如有这样的原始数据:

[
  {ticks: 50000.1234, losts:1},
  {ticks: 50000.1235, losts:2},
  {ticks: 50000.1266, losts:3}
]

此时组件会计算出所有可能的深度合并选项:0.0001,0.001,0.01,0.1,1,10,100,1000 当选择0.0001,则什么都不会发生 当选择0.001, 则小数点向前合并一位,最终展现给用户的数据就变成了:

{
  {ticks: 50000.1230, losts: 3},
  {ticks: 50000.1260, losts: 3}
}

因为小数点向前合并一位,就是说最后一位小数全变成0 然后50000.1234和50000.1235就都变成了50000.1230,这两个数值变成一样了,于是合并到一起,它们的lots相加变成3 其他选项以此类推

关于深度合并下拉框的值是怎么算出来的

会根据买方最前面挂单的价格进行计算,自动向前合并一位,直到无法再合并。


onRowClick(p, q)

当鼠标点击某一行数据时,会触发一次

返回值

p: {"ticks":47900,"lots":3.23456789,"total":9.458553034044943} 当前选中的数据:价格(ticks)/数量(lots)/累计(total) q: {"zi":"BTC","mu":"USDT","ziPoint":8,"muPoint":4} 当前交易对的信息:就是marketInfo参数的数据


choseChange(p)

当左上角按钮状态改变时触发一次

返回值

p: "center" 选择了第1个按钮,上下数据各展示一半/ "ask"选择了仅展示卖方数据/ "bid"选择了仅展示买方数据

注意事项

  • 组件宽高都是100%, 所以需要一个有大小的容器来装它。
  • 如果你需要更多自定义,可以直接/src下的内容复制到你自己项目里,自己改,就是个普通vue组件,直接用就行。
  • /src/App.vue是本体,/src/components下是简单封装了个select组件,/src/utils是一些数学函数。
  • 本组件内部的数学运算使用了big.js

  1. 更新:现在前端会自动进行深度合并计算。如果你们使用后端计算深度也没有关系,不影响
  2. 修复:修复了没有深度时下拉框的样式
