APIs

• configure(Object conf)
• extract(String url)
• parseWithEmbedly(String url [, String EmbedlyKey])
• parseMeta(String html, String url)
• getArticle(String html)
• absolutify(String baseURL, String url)
• purify(String url)

configure(Object conf)

{
  wordsPerMinute: Number, // default 300, use to estimate time to read
  blackList: Array, // a set of domain we don't want to parse
  exceptDomain: Array, // a set of domain that will be parsed using Embedly
  adsDomain: Array, // a set of domain that often contains utm_, pk_ in URLs we want to clean
  htmlRules: Object, // passed to sanitize-html to clean HTML, refer: https://www.npmjs.com/package/sanitize-html
  SoundCloudKey: String, // use to get audio duration. Get it here https://developers.soundcloud.com/
  YouTubeKey: String, // use to get video duration. Get it here https://console.developers.google.com/,
  EmbedlyKey: String, // use to extract with Embedly API. Refer http://docs.embed.ly/docs/extract
}

Default configurations may work for most case.

extract(String url)

Extract article data from specified url.

var ArticleParser = require('article-parser');

var url = 'http://yhoo.it/1MJUFov';

ArticleParser.extract(url).then((article) => {
  console.log(article);
}).catch((err) => {
  console.log(err);
});

Now article would be something like this:

{
  alias: 'how-to-stay-calm-when-you-know-you-ll-be-stressed-daniel-levitin-ted-talks-1449068980884',
  url: 'https://www.youtube.com/watch?v=8jPQjjsBbIc',
  canonicals: [ 'https://www.youtube.com/watch?v=8jPQjjsBbIc' ],

  domain: 'www.youtube.com',
  duration: 741,
  publishedTime: '2013-11-12T19:57:40+00:00'
}

parseWithEmbedly(String url [, String EmbedlyKey])

Extract article data from specified url using Embedly Extract API:

The second parameter is optional. If you've added your Embedly key via configure() method, you can ignore it here.

var ArticleParser = require('article-parser');

var url = 'http://yhoo.it/1MJUFov';

ArticleParser.parseWithEmbedly(url).then((article) => {
  console.log(article);
}).catch((err) => {
  console.log(err);
});

parseMeta(String html, String url)

Get meta data from webpage's html.

var ArticleParser = require('article-parser');
var fetch = require('node-fetch');

var url = 'https://medium.com/@ndaidong/setup-rocket-chat-within-10-minutes-2b00f3366c6';

fetch(url).then((res) => {
  return res.text();
}).then((html) => {
  let metaData = ArticleParser.parseMeta(html, url);
  return metaData;
});

Now metaData would be something like this:

{
  url: 'https://medium.com/@ndaidong/setup-rocket-chat-within-10-minutes-2b00f3366c6',
  canonical: 'https://medium.com/@ndaidong/setup-rocket-chat-within-10-minutes-2b00f3366c6',
  title: 'Setup Rocket Chat within 10 minutes',
  description: 'Do you want to get your own Slack app for your company or your team. Rocket Chat may be what you need.',

  publishedTime: '2013-11-12T19:57:40+00:00'
}

getArticle(String html)

Get main article content from webpage's html:

var ArticleParser = require('article-parser');
var fetch = require('node-fetch');

var url = 'https://medium.com/@ndaidong/setup-rocket-chat-within-10-minutes-2b00f3366c6';

fetch(url).then((res) => {
  return res.text();
}).then((html) => {
  let content = ArticleParser.getArticle(html);
  return content;
})
.then((article) => {
  console.log(article);
})
.catch((err) => {
  console.log(err);
});

Now content would be clean text of main article extracted from url.
