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 🙏

Taro小程序图片预加载组件

安装

npm install taro-preload

使用

在小程序首页,或者初始页面(进入小程序的第一个页面)引入Preload组件。

可以在不同页面重复引入,不会重复执行预加载的操作

import Taro, { Component } from '@tarojs/taro'
import {Preload} from 'taro-preload';

export default class Index extends Component{
  render () {
    return (
      <View className='index'>
        ...

        <Preload/>
      </View>
    )
  }
}

确保Preload组件挂载成功后,在任何页面,任何地方,都可以调用预加载命令。

import {preload} from 'taro-preload';

preload(['img1', 'img2']).then(() => {
  console.log('预加载结束')
})

API

function preload(data: string[], timeout?: number): Promise

data: 图片链接列表

timeout: 图片加载超时时间,默认1500ms,如果<0则不进行超时判断

Task.length: 需要加载的图片数量

Task.count: 未加载结束的图片数量

Task.loaded: 加载成功的图片列表

Task.error: 加载失败的图片列表
