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 🙏

node-jinja2-template

node 中,运行 jinja2 模板,并返回运行后的结果。

使用前准备

  1. 确保运行机器,已经安装 python
  2. 确保已经安装了 jinja2

使用

const path = require('path');
const Jinja2Template = require('../index');

const template = new Jinja2Template(
  [ 
    // jinja 文件,放置的目录列表
    path.resolve('./template') 
  ],
  {
    runFile: '被运行的 py 文件模板,请参考 python/run.py 进行编写,如果不指定,就使用默认的运行模板',
    idGenerator() {
      // 自定义每次运行的 文件 id,可不设置,保留 null
      return Date.now();
    }
  }
);

// .render('模板名字', 模板渲染的数据) => Promise
template.render('index.html', { name: 'da宗熊' })
  .then(function(res) {
    console.log(res.trim());
  });

原理

实际,使用子进程运行命令 python xxx.py,运行后将在控制台,print 出以下内容:

START=============@@@=============START
<div>我是jinja2生成的内容</div>
END=============@@@=============END

之后,通过正则,匹配出 jinja 生成的内容。

所以,调整 runFile 时,保持 print 的格式,是非常重要的~
