eleventy-plugin-embed-instagram

This Eleventy plugin automatically embeds Instagram photos and videos from URLs in markdown files.

Install in Eleventy

In your Eleventy project, install the plugin through npm:

$ npm i eleventy-plugin-embed-instagram

Then add it to your Eleventy config file (usually .eleventy.js):

const embedInstagram = require("eleventy-plugin-embed-instagram");

module.exports = function(eleventyConfig) {
  eleventyConfig.addPlugin(embedInstagram);
};

Usage

To embed an Instagram photo or video into any markdown page, paste its URL into a new line. The URL should be the only thing on that line.

Markdown file example:

...

Lorem ipsum dolor sit amet, consectetur adipiscing elit. Nam vehicula, elit vel condimentum porta, purus.

https://www.instagram.com/p/B9XK4J3jVui/

Maecenas non velit nibh. Aenean eu justo et odio commodo ornare. In scelerisque sapien at.

...

Result:

The plugin supports common URL variants as well. These will also work:

<!-- No protocol: -->

instagram.com/p/B9XK4J3jVui/
www.instagram.com/p/B9XK4J3jVui/

<!-- With or without HTTPS: -->

http://www.instagram.com/p/B9XK4J3jVui/
https://www.instagram.com/p/B9XK4J3jVui/

<!-- With or without 'www': -->

https://www.instagram.com/p/B9XK4J3jVui/
https://instagram.com/p/B9XK4J3jVui/

<!-- URLs with extra parameters: -->
https://www.instagram.com/p/B9XK4J3jVui/?foo=bar

Notes and caveats

• This plugin is deliberately designed only to embed when the URL is on its own line, and not inline with other text.
• To do this, it uses a regular expression to recognize Instagram URLs, wrapped in an HTML <p> tag. If your Markdown parser produces any other output, it won’t be recognized.
• I’ve tried to accommodate common variants, but there are conceivably valid Instagram URLs that wouldn’t get recognized. Please file an issue if you run into an edge case!
• This plugin uses transforms, so it alters Eleventy’s HTML output as it’s generated. It doesn’t alter the source markdown.
• By necessity, this plugin will add a call to Instagram’s third-party javascript file. It does this once per page, if that page contains an Instagram embed.
• Because the aspect ratio of Instagram media can vary widely, the embed is not currently responsive. By default, Instagram’s script injects an iframe with a hard-coded width of 326 pixels. I’ve opted to lead this default behavior intact.
• To make your Instagram embeds responsive, you can change their widths with CSS. Give them a standard pixel size, or set them to fill their full available horizontal width. Instagram’s embed script will automatically upscale them to fill the available space.

.eleventy-plugin-embed-instagram {
  width: 100%;
}

• You can change the class name to whatever you prefer by passing an options object when you configure the plugin in your .eleventy.js file:

module.exports = function(eleventyConfig) {
  eleventyConfig.addPlugin(embedInstagram, {
    embedClass: 'alternate-class-string'
});
};
