Usage

npm install article-parser

Then:

const {
  extract
} = require('article-parser');

const url = 'https://goo.gl/MV8Tkh';

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

APIs

Since v4, article-parser will focus only on its main mission: extract main readable content from given webpages, such as blog posts or news entries. Although it is still able to get other kinds of content like YouTube movies, SoundCloud media, etc, they are just additions.

extract(String url | String html)

Extract data from specified url or full HTML page content. Return: a Promise

Here is how we can use article-parser:

import {
  extract
} from 'article-parser';

const getArticle = async (url) => {
  try {
    const article = await extract(url);
    return article;
  } catch (err) {
    console.trace(err);
  }
};

In comparison to v3, the article object structure has been changed too. Now it looks like below:

{
  "url": URI String,
  "title": String,
  "description": String,
  "image": URI String,
  "author": String,
  "content": HTML String,
  "published": Date String,
  "source": String, // original publisher
  "links": Array, // list of alternative links
  "ttr": Number, // time to read in second, 0 = unknown
}
