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 🙏

在跟后端交互的时候,通常需要禁止页面交互,使页面展示为loading状态。通常的做法是在异步请求开始的时候,设置页面状态为loading,然后展示一个蒙层覆盖页面,然后在请求结束的时候再将页面设置为ready状态。这里提供一个vue插件,可以在页面异步行为的开始时显示加载状态,异步行为结束的时候关闭加载状态。

在跟后端交互的时候,通常需要禁止页面交互,使页面展示为loading状态。通常的做法是在异步请求开始的时候,设置页面状态为loading,然后展示一个蒙层覆盖页面,然后在请求结束的时候再将页面设置为ready状态。这里提供一个vue插件,可以在页面异步行为的开始时显示加载状态,异步行为结束的时候关闭加载状态。

安装

使用npm安装

npm install vue-sync-state --save

使用

在应用初始化时,安装插件。

import Vue from 'vue'
import sync from 'vue-sync-state'

Vue.use(sync)
...

使用 $sync 方法封装异步调用的方法。

注意:这里要求内部的方法需要返回一个Promise。

...
<div @click="$sync(handleClick)">
  默认样式
</div>

...

methods: {
  handleClick () {

    // 被封装的方法返回一个Promise
    return new Promise(resolve => {
      setTimeout(() => {
        resolve()
      }, 3000)
    })
  }
}

...

这里也提供第二个参数来配置加载时展示的组件和背景色。

自定义组件:

...
<div @click="$sync(handleClick, { spinner })">
  自定义组件
</div>

...

import { Circle4 } from 'vue-loading-spinner'

...

data() {
  return {
    spinner: Circle4
  }
},

methods: {
  handleClick () {

    // 被封装的方法返回一个Promise
    return new Promise(resolve => {
      setTimeout(() => {
        resolve()
      }, 3000)
    })
  }
}

...

自定义背景色:

<div @click="$sync(handleClick, { backgroundColor: 'rgba(0,0,0,0.1)'})">
  自定义背景色
</div>

也可以同时自定义组件和背景色。
