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 🙏

knc-render

基于koa和nunjucks的服务端组件化渲染方案


NPM version Build status Downloads

特性

  • 基于koa和nunjucks
  • 组件化开发
  • 需要搭配构建工具shaun使用

安装

  npm install knc-render --save

使用

启动

// template render
const app = new Koa();
const KncRender = require('knc-render');

// new KncRender(koaContext, renderOptions, [comboOptions]);
const kncRender = new KncRender(app, {
    ext: 'html', // 模板后缀名
    path: '', // 模板路径
    componentPath: '', // 组件路径
    componentDefaultTmpl: 'index', // 组件默认模板名
    staticURL: '/combo?', // 静态资源路径
    staticCombo: true, // 静态资源是否开启combo
    staticMap: {}, // 静态资源表
    filter: {}, // nunjucks模板过滤器
    dataFilter: function(data, extra) {}, // 数据过滤
    nunjucksConfig: { // nunjucks配置
        autoescape: true,
        watch: true
    }
}, {
    dir: '', // 读取文件目录
    ext: ['js', 'css'], // 允许读取文件的后缀名
    maxAge: 60 * 60 * 1000 // 缓存时间,默认一天
});

kncRender.start();

require

关闭combo的时候,require进来的资源为staticURL目录下的文件
打开combo的时候,require进来的资源应该是dir目录下的,包含在ext里面的后缀名的文件
{% require "c_list/index.js" %}

component

component可以有4个参数,name,data,theme,extra name为组件名,data为数据,theme为主题名,extra为额外参数,会直接做为dataFilter的第二个参数

{% component name="c_list",data="" %}
这种情况会找componentPath目录下的c_list目录下的[componentDefaultTmpl.ext]文件,并且直接拿data来进行渲染

资源表格式

{
    "css/header.css": "css/header-423dsdol.css",
    "js/header.js": "js/header-gk34o1k3.js" 
}

占位符

如果html文件里面包含<!-- [STYLE PLACEHOLDER] -->,则样式相关会插入这个位置,如果没有默认</head>之前;
如果html文件里面包含<!-- [SCRIPT PLACEHOLDER] -->,则脚本相关会插入这个位置,如果没有默认</body>之前

组件规范

- c_header
 |- images
 |- scss
 |- js
 |- index.html
 |- index.scss
