### From a URL

```sh
>>> import sneakpeek
>>> from pprint import pprint

>>> link = sneakpeek.SneakPeek("https://www.youtube.com/watch?v=dQw4w9WgXcQ")
>>> link.fetch()
>>> link.is_valid()
True
>>> pprint(link)
{'description': 'The official video for “Never Gonna Give You Up” by Rick '

 'video:type': 'text/html',
 'video:url': 'https://www.youtube.com/embed/dQw4w9WgXcQ',
 'video:width': '1280'}

>>> link = sneakpeek.SneakPeek(url="https://codingcoffee.dev")
>>> link.fetch()
>>> pprint(link)
{'description': 'A generalist with multi faceted interests and extensive '
                'experience with DevOps, System Design and Full Stack '

                'have a niche for optimizing and customizing things to the '

```

Use `scrape=True` to fetch data using scraping instead of relying on open graph tags

```sh
>>> link = sneakpeek.SneakPeek(url="https://news.ycombinator.com/item?id=23812063", scrape=True)
>>> link.fetch()
>>> pprint(link)
{'description': '',
 'domain': 'news.ycombinator.com',
 'image': 'y18.gif',
 'scrape': True,
 'title': 'WireGuard as VPN Server on Kubernetes with AdBlocking | Hacker News',
 'type': 'other',
 'url': 'https://news.ycombinator.com/item?id=23812063'}
 ```

## Contribution

Have better suggestions to optimize the server image? Found some typos? Need special handling for a new website? Found a bug? Go ahead and create an [Issue](https://github.com/codingcoffee/sneakpeek/issues)! Contributions of any kind welcome!

Want to work on a TODO? Its always a good idea to talk about what are going to do before you actually start it, so frustration can be avoided.

Some rules for coding:

- Use the code style the project uses
- For each feature, make a seperate branch, so it can be reviewed separately
- Use commits with a good description, so everyone can see what you did
