Parse only

By default, the URL of the favicon is retrieved as a relative path, but you can retrieve it as an absolute path by setting the URL.

import { parseOgp } from "ogp-fetcher";

const html = `
<html lang="ja">
  <head>
    <meta charset="UTF-8" />
    <meta property="og:title" content="title" />
    <meta property="og:description" content="description" />
    <meta property="og:locale" content="locale" />
    <meta property="og:type" content="type" />
    <meta property="og:url" content="https://example.com" />
    <meta property="og:image:width" content="200" />
    <meta property="og:image:height" content="100" />
    <meta property="og:image" content="https://example.com/image.png" />
    <link rel="icon" href="/image/favicon.ico">
    <title>Hello World</title>
  </head>
  <body>
    <h1>Hello World</h1>
  </body>
</html>
`;

const withRelativeIconPath = parseOgp([{ html: html }]);
console.log(withRelativeIconPath);
// console
// [
//   {
//     'og:title': 'title',
//     'og:description': 'description',

//     'og:image': 'https://example.com/image.png',
//     icon: '/image/favicon.ico'
//   }
// ]

const withAbsoluteIconPath = parseOgp([
  { url: "https://example.com", html: html },
]);
console.log(withAbsoluteIconPath);
// console

Fetch and parse from Md

By default, the regular expression /^<(https:\/\/.*?)> *?$/gims, but you can also customize the regular expression.

import { fetchOgpFromMd } from "ogp-fetcher";

const md = `
# TestMd

## GitHub
<https://github.com>  

**Facebook**
<https://facebook.com>

### npm
@https://www.npmjs.com/

`;

const fetch = async () => {
  const ogp = await fetchOgpFromMd(md);
  console.log(ogp);
};

fetch();
