open-graph-scraper
Advanced tools
A simple node module(with TypeScript declarations) for scraping Open Graph and Twitter Card and other metadata off a site.
Note: open-graph-scraper doesn't support browser usage at this time but you can use open-graph-scraper-lite if you already have the HTML and can't use Node's Fetch API.
npm install open-graph-scraper --save
const ogs = require('open-graph-scraper');
const options = { url: 'http://ogp.me/' };
ogs(options)
.then((data) => {
const { error, html, result, response } = data;
console.log('error:', error); // This returns true or false. True if there was an error. The error itself is inside the result object.
console.log('html:', html); // This contains the HTML of page
console.log('result:', result); // This contains all of the Open Graph results
console.log('response:', response); // This contains response from the Fetch API
})
Check the return for a success flag. If success is set to true, then the url input was valid. Otherwise it will be set to false. The above example will return something like...
{
ogTitle: 'Open Graph protocol',
ogType: 'website',
ogUrl: 'https://ogp.me/',
ogDescription: 'The Open Graph protocol enables any web page to become a rich object in a social graph.',
ogImage: [
{
height: '300',
type: 'image/png',
url: 'https://ogp.me/logo.png',
width: '300'
}
],
charset: 'utf-8',
requestUrl: 'http://ogp.me/',
success: true
}
| Name | Info | Default Value | Required |
|---|---|---|---|
| url | URL of the site. | x | |
| html | You can pass in an HTML string to run ogs on it. (use without options.url) | ||
| fetchOptions | Options that are used by the Fetch API | {} | |
| timeout | Request timeout for Fetch (Default is 10 seconds) | 10 | |
| blacklist | Pass in an array of sites you don't want ogs to run on. | [] | |
| onlyGetOpenGraphInfo | Only fetch open graph info and don't fall back on anything else. | false | |
| customMetaTags | Here you can define custom meta tags you want to scrape. | [] | |
| urlValidatorSettings | Sets the options used by validator.js for testing the URL | Here |
Note: open-graph-scraper uses the Fetch API for requests and most of Fetch's options should work as open-graph-scraper's fetchOptions options.
const ogs = require('open-graph-scraper');
const options = {
url: 'https://github.com/jshemas/openGraphScraper',
customMetaTags: [{
multiple: false, // is there more than one of these tags on a page (normally this is false)
property: 'hostname', // meta tag name/property attribute
fieldName: 'hostnameMetaTag', // name of the result variable
}],
};
ogs(options)
.then((data) => {
const { result } = data;
console.log('hostnameMetaTag:', result.customMetaTags.hostnameMetaTag); // hostnameMetaTag: github.com
})
const ogs = require('open-graph-scraper');
const options = {
html: `<html><head>
<link rel="icon" type="image/png" href="https://bar.com/foo.png" />
<meta charset="utf-8" />
<meta property="og:description" name="og:description" content="html description example" />
<meta property="og:image" name="og:image" content="https://www.foo.com/bar.jpg" />
<meta property="og:title" name="og:title" content="foobar" />
<meta property="og:type" name="og:type" content="website" />
</head></html>`
};
ogs(options)
.then((data) => {
const { result } = data;
console.log('result:', result);
// result: {
// ogDescription: 'html description example',
// ogTitle: 'foobar',
// ogType: 'website',
// ogImage: [ { url: 'https://www.foo.com/bar.jpg', type: 'jpg' } ],
// favicon: 'https://bar.com/foo.png',
// charset: 'utf-8',
// success: true
// }
})
The request header is set to undici by default. Some sites might block this, and changing the userAgent might work. If not you can try using a proxy for the request and then pass the html into open-graph-scraper.
const ogs = require("open-graph-scraper");
const userAgent = 'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/112.0.0.0 Safari/537.36';
ogs({ url: 'https://www.wikipedia.org/', fetchOptions: { headers: { 'user-agent': userAgent } } })
.then((data) => {
const { error, html, result, response } = data;
console.log('error:', error); // This returns true or false. True if there was an error. The error itself is inside the result object.
console.log('html:', html); // This contains the HTML of page
console.log('result:', result); // This contains all of the Open Graph results
console.log('response:', response); // This contains response from the Fetch API
})
Inside the example folder contains a simple express app where you can run npm ci && npm run start to spin up. Once the app is running, open a web browser and go to http://localhost:3000/scraper?url=http://ogp.me/ to test it out. There is also a Dockerfile if you want to run this example app in a docker container.
