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 🙏

Readme

vue3-screen-scale

用作屏幕缩放适配,尤其适用于大屏。

安装

第一步:npm install vue3-screen-scale --save
第二步:在main.js文件中引入指令文件
import { scale } from 'vue3-screen-scale';
第三步:在main.js中注册指令
app.directive('scale',scale);

用法

在项目的某个dom元素上使用指令,通常为根级元素

<div class="base-page" v-scale="{width:1920,height:1080}"></div>
width,height代表页面的原始尺寸,缩放均是根据它进行放缩,如果指令v-scale未添加额外参数,则需要在页面地址上添加参数scale,例如:www.xxx.com/#/?scale=0,参数值为0,表示同时会以当前屏幕宽和高进行缩放,页面通常会变形(除非屏幕宽高比刚好等于原始尺寸的宽高比),值为1代表以宽度进行同比例缩放,值为2代表以高度进行同比例缩放。
<div class="base-page" v-scale:1="{width:1920,height:1080}"></div>
如果指令带参数,则页面地址无需添加scale参数,指令参数值就代表缩放类型,本例就代表根据宽度进行同比缩放
