metadata-scraper

David

A Javascript library for scraping/parsing metadata from a web page.

👋 Introduction

metadata-scraper is a Javascript library which scrapes/parses metadata from web pages. You only need to supply it with a URL or an HTML string and it will use different rules to find the most relevant metadata like:

Title
Description
Favicons/Images
Language
Keywords
Author
and more (full list below)

🚀 Get started

Install metadata-scraper via npm:

1npm install metadata-scraper

📚 Usage

Import metadata-scraper and pass it a URL or options object:

1const getMetaData = require('metadata-scraper')
2
3const url = 'https://github.com/BetaHuhn/metadata-scraper'
4
5getMetaData(url).then((data) => {
6	console.log(data)
7})

Or with async/await:

1const getMetaData = require('metadata-scraper')
2
3async function run() {
4	const url = 'https://github.com/BetaHuhn/metadata-scraper'
5	const data = await getMetaData(url)
6	console.log(data)
7}
8
9run()

This will return:

1{
2	title: 'BetaHuhn/metadata-scraper',
3	description: 'A Javascript library for scraping/parsing metadata from a web page.',
4	language: 'en',
5	url: 'https://github.com/BetaHuhn/metadata-scraper',
6	provider: 'GitHub',
7	twitter: '@github',
8	image: 'https://avatars1.githubusercontent.com/u/51766171?s=400&v=4',
9	icon: 'https://github.githubassets.com/favicons/favicon.svg'
10}

You can see a list of all metadata which metadata-scraper tries to scrape below.

⚙️ Configuration

You can change the behaviour of metadata-scraper by passing an options object:

1const getMetaData = require('metadata-scraper')
2
3const options = {
4	url: 'https://github.com/BetaHuhn/metadata-scraper', // URL of web page
5	maxRedirects: 0, // Maximum number of redirects to follow (default: 5)
6	ua: 'MyApp', // Specify User-Agent header
7	lang: 'de-CH', // Specify Accept-Language header
8	timeout: 1000, // Request timeout in milliseconds (default: 10000ms)
9	forceImageHttps: false, // Force all image URLs to use https (default: true)
10	customRules: {} // more info below
11}
12
13getMetaData(options).then((data) => {
14	console.log(data)
15})

You can specify the URL by either passing it as the first parameter, or by setting it in the options object.

📖 Examples

Here are some examples on how to use metadata-scraper:

Basic

Pass a URL as the first parameter and metadata-scraper automatically scrapes it and returns everything it finds:

1const getMetaData = require('metadata-scraper')
2const data = await getMetaData('https://github.com/BetaHuhn/metadata-scraper')

Example file located at examples/basic.js.

HTML String

If you already have an HTML string and don't want metadata-scraper to make an http request, specify it in the options object:

1const getMetaData = require('metadata-scraper')
2
3const html = `
4	<meta name="og:title" content="Example">
5	<meta name="og:description" content="This is an example.">
6`
7
8const options {
9	html: html, 
10	url: 'https://example.com' // Optional URL to make relative image paths absolute
11}
12
13const data = await getMetaData(options)

Example file located at examples/html.js.

Custom Rules

Look at the rules.ts file in the src directory to see all rules which will be used.

You can expand metadata-scraper easily by specifying custom rules:

1const getMetaData = require('metadata-scraper')
2
3const options = {
4	url: 'https://github.com/BetaHuhn/metadata-scraper',
5	customRules: {
6		name: {
7			rules: [
8				[ 'meta[name="customName"][content]', (element) => element.getAttribute('content') ]
9			],
10			processor: (text) => text.toLowerCase()
11		}
12	}
13}
14
15const data = await getMetaData(options)

customRules needs to contain one or more objects, where the key (name above) will identify the value in the returned data.

You can then specify different rules for each item in the rules array.

The first item is the query which gets inserted into the browsers querySelector function, and the second item is a function which gets passed the HTML element:

1[ 'querySelector', (element) => element.innerText ]

You can also specify a processor function which will process/transform the result of one of the matched rules:

1{
2	processor: (text) => text.toLowerCase()
3}

If you find a useful rule, let me know and I will add it (or create a PR yourself).

Example file located at examples/custom.js.

📇 All metadata

Here's what metadata-scraper currently tries to scrape:

1{
2	title: 'Title of page or article',
3	description: 'Description of page or article',
4	language: 'Language of page or article',
5	type: 'Page type',
6	url: 'URL of page',
7	provider: 'Page provider',
8	keywords: ['array', 'of', 'keywords'],
9	section: 'Section/Category of page',
10	author: 'Article author',
11	published: 1605221765, // Date the article was published
12	modified: 1605221765, // Date the article was modified
13	robots: ['array', 'for', 'robots'],
14	copyright: 'Page copyright',
15	email: 'Contact email',
16	twitter: 'Twitter handle',
17	facebook: 'Facebook account id',
18	image: 'Image URL',
19	icon: 'Favicon URL',
20	video: 'Video URL',
21	audio: 'Audio URL'
22}

If you find a useful metatag, let me know and I will add it (or create a PR yourself).
