markdown-it 是一个辅助解析 markdown 的库，可以完成从 # test 到 <h1>test</h1> 的转换。 它同时支持浏览器环境和 Node 环境，本质上和 babel 类似，不同之处在于，babel 解析的是 JavaScript。

安装

npm install markdown-it --save
bower install markdown-it --save

例子

// node.js, "classic" way:
var MarkdownIt = require('markdown-it'),
    md = new MarkdownIt();
var result = md.render('# markdown-it rulezz!');

// node.js, the same, but with sugar:
var md = require('markdown-it')();
var result = md.render('# markdown-it rulezz!');

// browser without AMD, added to "window" on script load
// Note, there is no dash in "markdownit".
var md = window.markdownit();
var result = md.render('# markdown-it rulezz!');

单行渲染，无段落换行： 

var md = require('markdown-it')();
var result = md.renderInline('__markdown-it__ rulezz!');
