The Mercury Parser extracts the bits that humans care about from any URL you give it. That includes article content, titles, authors, published dates, excerpts, lead images, and more.

Mercury Parser powers the [Mercury AMP Converter](https://mercury.postlight.com/amp-converter/) and [Mercury Reader](https://mercury.postlight.com/reader/), a Chrome extension that removes ads and distractions, leaving only text and images for a beautiful reading view on any site.

## How? Like this.

### Installation

```bash
# If you're using yarn
yarn add @postlight/mercury-parser

# If you're using npm
npm install @postlight/mercury-parser
```

### Usage

```javascript
import Mercury from '@postlight/mercury-parser';

Mercury.parse(url).then(result => console.log(result););

// NOTE: When used in the browser, you can omit the URL argument
// and simply run `Mercury.parse()` to parse the current page.

```

The result looks like this:

```json
{
  "title": "Thunder (mascot)",
  "content": "<div><div><p>This is the content of the page!</div></div>",
  "author": "Wikipedia Contributors",
  "date_published": "2016-09-16T20:56:00.000Z",
  "lead_image_url": null,
  "dek": null,
  "next_page_url": null,
  "url": "https://en.wikipedia.org/wiki/Thunder_(mascot)",
  "domain": "en.wikipedia.org",
  "excerpt": "Thunder Thunder is the stage name for the horse who is the official live animal mascot for the Denver Broncos",
  "word_count": 4677,
  "direction": "ltr",
  "total_pages": 1,
  "rendered_pages": 1
}
```

If Mercury is unable to find a field, that field will return `null`.
