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 🙏

Meaning

在编写 vue 代码的过程中,经常会遇到需要在模板中渲染一些不会改变的变量,由于需要在放到模板中,我们常常把这个变量放到 data 属性中,vue 会对 data 中的数据进行观察,这样便会造成将「数据」转换为「响应式对象」的性能开销,尤其是当这些数据较多且复杂时。因此有必要实现一种模式,既能跳过 vue 的观察机制,又能使变量可以在 vue 模板中被使用,vue-immutable 由此诞生 ,优化 vue 对 immutable 数据的处理,immutable 数据将被全局消费。

Install

使用 npm 安装: npm install vue-immutable

使用 yarn 安装: yarn add vue-immutable

Start

// main.js
import Vue from "vue";
import App from "./App.vue";
import VueImmutable from "vue-immutable";

Vue.use(VueImmutable);

new Vue({
  el: "#app",
  immutable: {
    msg: "hello world"
  },
  components: { App },
  template: "<App/>"
});
// App.vue
<template>
  <div id="app">
    <h1>{{ $immutable.msg }}</h1>
  </div>
</template>
