chompjs can be used in web scrapping for turning JavaScript objects embedded in pages into valid Python dictionaries.
In web scraping this is particularly useful for parsing Javascript variables like:
python
import chompjs
js = """
var myObj = {
myMethod: function(params) {
// ...
},
myValue: 100
}
"""
chompjs.parse_js_object(js, json_params={'strict': False})
{'myMethod': 'function(params) {\n // ...\n }', 'myValue': 100}
In practice this can be used to extract hidden JSON data like data from <script id=__NEXT_DATA__> elements
from nextjs (and similar) websites. Unlike json.loads command chompjs can ingest json documents that contain
javascript natives like functions making it a super easy way to scrape hidden web data objects.
PHP library to get information from any web page (using oembed, opengraph, twitter-cards, scrapping the html, etc).
It's compatible with any web service (youtube, vimeo, flickr, instagram, etc) and
has adapters to some sites like (archive.org, github, facebook, etc).
```python
# basic use
import chompjs
js = """
var myObj = {
myMethod: function(params) {
// ...
},
myValue: 100
}
"""
chompjs.parse_js_object(js, json_params={'strict': False})
{'myMethod': 'function(params) {\n // ...\n }', 'myValue': 100}
# example how to use with hidden data parsing:
import httpx
import chompjs
from parsel import Selector
response = httpx.get("http://example.com")
hidden_script = Selector(response.text).css("script#__NEXT_DATA__::text").get()
data = chompjs.parse_js_object(hidden_script)
print(data['props'])
```
```javascript
use Embed\Embed;
$embed = new Embed();
//Load any url:
$info = $embed->get('https://www.youtube.com/watch?v=PP1xn5wHtxE');
//Get content info
$info->title; //The page title
$info->description; //The page description
$info->url; //The canonical url
$info->keywords; //The page keywords
$info->image; //The thumbnail or main image
$info->code->html; //The code to embed the image, video, etc
$info->code->width; //The exact width of the embed code (if exists)
$info->code->height; //The exact height of the embed code (if exists)
$info->code->ratio; //The aspect ratio (width/height)
$info->authorName; //The resource author
$info->authorUrl; //The author url
$info->cms; //The cms used
$info->language; //The language of the page
$info->languages; //The alternative languages
$info->providerName; //The provider name of the page (Youtube, Twitter, Instagram, etc)
$info->providerUrl; //The provider url
$info->icon; //The big icon of the site
$info->favicon; //The favicon of the site (an .ico file or a png with up to 32x32px)
$info->publishedTime; //The published time of the resource
$info->license; //The license url of the resource
$info->feeds; //The RSS/Atom feeds
