Use marked and prism.js to parse markdown and add syntax highlighting in Node.js

marked-and-prism.js

// Versions: marked v0.6.2, prismjs v1.15.0

let marked = require('marked');
let prism = require('prismjs');
let loadLanguages = require('prismjs/components/');

loadLanguages(['javascript', 'jsx', 'css', 'markup', 'bash', 'json']);

marked.setOptions({
  highlight: function(code, lang) {
    if (prism.languages[lang]) {
      return prism.highlight(code, prism.languages[lang], lang);
    } else {
      return code;
    }
  }
});

let someMarkdown = "```javascript\nlet x = 2;```";

let html = marked.parse(someMarkdown)
