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 🙏

JavaScript 响应式模板引擎

简介

js-template 可以用js生成 HTML 页面。而且非常小,不到1K。并且支持响应式

构建

请先安装rollup.js

cd reactivity-template-js
npm install
npm run build

安装

npm i reactivity-template

引入

引入

import compile from 'reactivity-template'

或在html文件中直接引入iife

<script src="./dist/template.iife.js"></script>

使用

一个demo,在id="demo"的div里是模板,然后通过 template.compile 编译。(该示例在 index.html 里)

<div id="demo">
    <p>Hello <%= name %></p>
    <% if (!login) { %>
        <p>请登录</p>    
    <% } %>
</div>
<script>
    let demo_template = template.compile('demo')
    document.getElementById('demo').innerHTML = demo_template({
        name:'saobby',
        login:true
    })
</script>

import compile from 'reactivity-template'

let demo_template = compile('demo')
document.getElementById('demo').innerHTML = demo_template({
    name: 'saobby',
    login: true
})

template-js 有两种标签,分别是<% %><%= %>

<%= %>: 输出数据到模板

<% %> : 脚本标签,可以执行Js

响应式

有时在数据更改时调用渲染有点麻烦,所以你可以使用响应式让templateJS来监测数据的改变并重新渲染。

只需要在template.compile 里加上 reactive=true 即可使用响应式

<div id="demo">
    <p>Hello <%= name %></p>
    <% if (!login) { %>
        <p>请登录</p>    
    <% } %>
    <%= time %>
</div>
<script>
    let data = {
        name:'saobby',
        login:true,
        time:0,
    }
    data = template.compile('demo',data,reactive=true);

    setInterval(()=>{
        data.time ++
    },1000)
</script>

以上代码的template.compile返回了一个Proxy,当data值改变时重新渲染。

若你想获取整个data值的话请使用data.value。否则请用data.key

若你想要赋值整个data的话请data.value = {...}

但是只想修改它的属性的话可以直接data.key = ...修改。比如上面的代码修改data的time就可以直接data.time ++
