APIs

.extract(String url [, Object params])

Load and extract oembed data.

Example:

import { extract } from 'oembed-parser'

const getOembed = async (url) => {
  try {
    const oembed = await extract(url)
    return oembed
  } catch (err) {
    console.trace(err)
    return null
  }
}

const data = getOembed('your url')
console.log(data)

Optional argument params can be useful when you want to specify some additional customizations.

Here are several popular params:

• maxwidth: max width of embed size
• maxheight: max height of embed size
• theme: e.g, dark or light
• lang: e.g, 'en', 'fr', 'cn', 'vi', etc

Note that some params are supported by these providers but not by the others. Please see the provider's oEmbed API docs carefully for exact information.

.hasProvider(String URL)

Check if a URL matches with any provider in the list.

Examples:

import { hasProvider } from 'oembed-parser'

hasProvider('https://www.youtube.com/watch?v=ciS8aCrX-9s') // return true
hasProvider('https://trello.com/b/BO3bg7yn/notes') // return false

.findProvider(String URL)

Get the provider which is relevant to given URL.

For example:

import { findProvider } from 'oembed-parser'

findProvider('https://www.facebook.com/video.php?v=999999999')

Result looks like below:

{
  fetchEndpoint: 'https://graph.facebook.com/v10.0/oembed_video',
  providerName: 'Facebook',
  providerUrl: 'https://www.facebook.com/'
}

.setProviderList(Array providers)

Apply a list of providers to use, overriding the default.

This can be useful for whitelisting only certain providers, or for adding custom providers.

Default list of resource providers is synchronized from oembed.com.

For example:

import { setProviderList } from 'oembed-parser'

const providers = [
  {
    provider_name: 'Alpha',
    provider_url: 'https://alpha.com',
    endpoints: [
      // endpoint definition here
    ]
  },
  {
    provider_name: 'Beta',
    provider_url: 'https://beta.com',
    endpoints: [
      // endpoint definition here
    ]
  }
]

setProviderList(providers)

.setRequestOptions(Object requestOptions)

Define options to call oembed HTTP request.

oembed-parser is using axios to send HTTP requests. Please refer axios' request config for more info.

Default option:

{
  headers: {
    'user-agent': 'Mozilla/5.0 (X11; Linux x86_64; rv:95.0) Gecko/20100101 Firefox/95.0',
    accept: 'application/json; charset=utf-8'
  },
  responseType: 'json',
  responseEncoding: 'utf8',
  timeout: 6e4,
  maxRedirects: 3
}

Facebook and Instagram

Since October 24 2020, Facebook have deprecated their legacy urls and applied a new Facebook oEmbed endpoints.

Technically, now we have to use Facebook Graph API, with the access token from a valid and live Facebook app. oembed-parser will try to get these values from environment variables, so please define them, for example:

export FACEBOOK_APP_ID=your_app_id
export FACEBOOK_CLIENT_TOKEN=your_client_token
