The problem

You're using @remark-embedder/core to automatically convert URLs in your markdown to the embedded version of those URLs and want to have a transform for providers that support an oEmbed API. Learn more about oEmbed from oembed.com

This solution

This is a @remark-embedder transform for supported oembed API providers. Find the list of supported providers on oembed.com.

Installation

This module is distributed via npm which is bundled with node and should be installed as one of your project's dependencies:

npm install @remark-embedder/transformer-oembed

Usage

import remarkEmbedder from '@remark-embedder/core'
import oembedTransformer from '@remark-embedder/transformer-oembed'
// or, if you're using CommonJS require:
// const {default: oembedTransformer} = require('@remark-embedder/transformer-oembed')
import remark from 'remark'
import html from 'remark-html'

const exampleMarkdown = `
# My favorite YouTube video

[This](https://www.youtube.com/watch?v=dQw4w9WgXcQ) is a great YouTube video.
Watch it here:

https://www.youtube.com/watch?v=dQw4w9WgXcQ

Isn't it great!?
`

async function go() {
  const result = await remark()
    .use(remarkEmbedder, {
      transformers: [oembedTransformer],
    })
    .use(html)
    .process(exampleMarkdown)

  console.log(result.toString())
}

go()

This will result in:

<h1>My favorite YouTube video</h1>
<p>
  <a href="https://www.youtube.com/watch?v=dQw4w9WgXcQ">This</a> is a great
  YouTube video. Watch it here:
</p>
<iframe
  width="200"
  height="113"
  src="https://www.youtube.com/embed/dQw4w9WgXcQ?feature=oembed"
  frameborder="0"
  allow="accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture"
  allowfullscreen
></iframe>
<p>Isn't it great!?</p>

Config

Some oembed providers offer special configuration via query parameters. You can provide those via config:

// ...
import type {Config} from '@remark-embedder/transformer-oembed'

// ...

async function go() {
  const result = await remark()
    .use(remarkEmbedder, {
      transformers: [
        [
          oembedTransformer,
          {params: {theme: 'dark', dnt: true, omit_script: true}} as Config,
        ],
      ],
    })
    .use(html)
    .process(`https://twitter.com/kentcdodds/status/783161196945944580`)

  console.log(result.toString())
}

// ...

That results in (notice the data- attributes which are specific to twitter's oEmbed API):

<blockquote class="twitter-tweet" data-dnt="true" data-theme="dark">
  <p lang="en" dir="ltr">
    I spent a few minutes working on this, just for you all. I promise, it wont
    disappoint. Though it may surprise πŸŽ‰<br /><br />πŸ™

This could also be used to provide an access token for providers that require this (like Instagram).

Config as a function

You can also provide configuration as a function so you can determine what configuration to give based on the provider and/or the URL. Like so:

const oembedConfig: Config = ({url, provider}) => {
  if (provider.provider_name === 'Instagram') {
    return {
      params: {access_token: '{app-id}|{client-token}'},
    }
  }
}
const remarkEmbedderConfig = {
  transformers: [[oembedTransformer, oembedConfig]],
}
// ... etc...

Inspiration

It's a long story... Check out the inspiration on @remark-embedder/core

Other Solutions

  • remark-oembed: This one requires client-side JS to work which was unacceptable for our use cases.
