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.

|
### 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`.
