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

Koa JSX render

像写React一样写模板
Warning: JSX作为模板引擎无疑是低效的

Install

$ npm install koa-jsx-render --save-dev

一般书写JSX无疑需要babel 推荐使用babel-node来处理,更多细节可以查看babel/example-node-server

$ npm install babel-cli babel-preset-react --save-dev

对应的.babelrc,

{
  "presets": [
    "react"
  ]
}

Usage

const { join } = require('path');
const Koa = require('koa');
const Router = require('koa-router');
const jsx = require('koa-jsx-render');

const app = new Koa();

// jsx 是一个koa middleware, 附加一个`render`方法到koa context
app.use(jsx({
  viewPath: join(__dirname, 'views'), // 模版文件所在目录, 模板文件即stateless组件
  extname: '.jsx', // 模板文件扩展名。
  locals: {}, // 全局变量, 作为模板组件props
}));

const router = new Router();
router.get('/', (ctx) => {
  // `render`第一个参数为模板组件相对路径,不用指定扩展名,支持多级目录
  // `render`第二个参数为暴露给模板组件的数据,直接作为`props`
  // `render`执行 `ReactDOMServer.renderToStaticMarkup`, 
  // 并且`ctx.type = 'text/html'`
  ctx.render('index', {
    title: 'Koa JSX Example',
    slogan: 'Demacia!',
  });
});
app.use(router.routes());

app.listen(3000);
console.log('Listening on port 3000');
