converts URLs to embed codes

Project description

Turns links into embed codes. Useful for any system accepting user inputs which wants to make it easier for the user to add rich content and safer for the platform at the same time by not allowing any direct iframe tags.


Here is a quick example:

>>> from embeddify import Embedder
>>> embedder = Embedder()
>>> embedder("")
<iframe width="560" height="315" src="" frameborder="0" allowfullscreen></iframe>

This works right now for

  • (plugin name: youtube)

  • (plugin name: vimeo)

  • (plugin name: flickr)

  • (plugin name: slideshare)

  • videos (plugin name: facebookvideos)

The raw OEmbed data can be accessed via the data attribute of the result if the result is an OEmbedMarkup instance:

>>> result = embedder("")
>>> isinstance(result, embedder.OEmbedMarkup)

If a link can not be converted then the link will be returned.


You can configure the embedding tool by giving it a width and height to be used. This is given as maximum width/height to the oEmbed endpoints of the services and thus the resulting object might be smaller.

You can configure this for all embed plugins generically like this:

embedder = Embedder(width=100, height=100)

You can also configure it on a per plugin basis using the plugin name mentioned above like this:

plugin_config = {
    'youtube': {'width' : 200},
    'slideshare': {'width' : 500},
embedder = Embedder(plugin_config = plugin_config)

The plugin specific configuration overwrites the generic configuration.

You can also pass in arguments on a call by call basis like this:

embedder = Embedder()
embedder("", width=200)


Some providers support autoplay. You can use it with the autoplay setting:

embedder = Embedder(autoplay=True)

Normally YouTube wouldn’t support this setting, but the YouTube plugin handles it by rewriting the returned HTML code. This may break if YouTube ever changes the HTML code.

Additional parameters

Some OEmbed providers allow additional parameters. For example Vimeo allows autoplay:

>>> embedder('', params=dict(autoplay=True))
<iframe src="" width="420" height="315" frameborder="0" title="Intro Presentation for the Open Platforms Panel at the Community &amp; Marketing Summit" webkitallowfullscreen mozallowfullscreen allowfullscreen></iframe>

Choosing which plugins to use

If you don’t want all the plugins to be active you can choose which ones you want to use by providing a list of plugins to use like this:

import embeddify
plugins = [embeddify.YouTube(), embeddify.Vimeo()] # only video
embedder = Embedder(plugins = plugins)

Creating your own plugins

In order to extend the functionality with additional services you can create your own plugins. Depending on the service and whether it provides an oEmbed endpoint or not you can one of two base classes, Plugin or OEmbedPlugin.

Using an oEmbed endpoint

In order to write a plugin for an oEmbed enabled service you need to know it’s endpoint. For instance the YouTube implementation simply looks like this:

from embeddify import OEmbedPlugin

class YouTube(OEmbedPlugin):
    """converts youtube links into embeds

    api_url = ""

    def test(self, parts):
        """test if the plugin is able to convert that link"""
        return "" in parts.netloc

So you simply need to put in the URL of the endpoint and a test() method. This gets the result of the urlparse.urlparse() call as input and usually simply checks the netloc attribute for the right domain. If it returns False the next plugin will be tried, if it returns True the endpoint will be called and in case that call was successful, the embed code will be returned. Otherwise again the next plugin will be tried.

Using a plain plugin

If there is no oEmbed endpoint available or you want to create a plugin without an external call, you can derive from the Plugin class like so:

from embeddify import Plugin

class ExamplePlugin(Plugin):

    default = {
        'width' : 200,
        'height' : 300,

    def __call__(self, parts, config = {}):
        if "" in parts.netloc:
            return """<iframe src="something" width="%(width)s"></iframe>""" %config['width']
        return None

Again you get the results of urlparse.urlparse() passed into the plugin as well as a config dictionary. You then have to test whether your plugin knows about this service and if you do, just return a string with the embed code. If your plugin is not responsible or something else went wrong, simply return None. Then the next plugin will be tried.

In order to accept configuration, simply create a default dictionary in the class. This will be copied to your config and updated with plugin specific configuration and call by call configuration and then passed in as config parameter. So you shouldn’t have to do any modifications on it, just make sure you provide some default value.
