markdown-it-iframe

Iframe (<iframe>) tag plugin for markdown-it markdown parser.

v1.+ requires markdown-it v4.+, see changelog.

Markdown:

Below will render an iframe

/i/https://www.youtube.com/embed/qkcx0kf6jME

HTML:

<p>Below will render an iframe</p>
<div class="iframe-container">
<iframe frameborder="0" src="https://www.youtube.com/embed/qkcx0kf6jME"></iframe>
</div>

Install

node.js, browser:

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

Use

var md = require('markdown-it')()
            .use(require('markdown-it-iframe'));

md.render(/*...*/) // see example above

markdown-it-iframe also supports the following options:

{
    allowfullscreen: true,
    width: 800,
    height: 600,
    frameborder: 1, // default: 0
    renderIframe: false // default: true
}

If you want to do a live preview of markdown rendering you will run into performance issues when the user is typing out a URL for the iframe. The reason for this is that markdown-it tries to render the URL being typed out with every keystroke. To combat this you can specify renderIframe: false. This will print a message with the markdown instead of the actual iframe.

Differences in browser. If you load script directly into the page, without package system, module will add itself globally as window.markdownitIframe.
