npm run test-cov

Usage

JavaScript

const ogp = require('ogp-parser');

TypeScript

import ogp from 'ogp-parser'

Example

From v0.5, we have supported to extract oEmbed information. To extract oEmbed, we will use any href attribute in the link tag that has either types:

  • application/json+oembed
  • text/xml+oembed
const ogp = require("ogpParser");
console.log("URL:"+url);

ogp(url).then(function(data) {
    console.log(JSON.stringify(data, null, "    "));
}).catch(function(error) {
    console.error(error);
});

Result

{
    "title": "うきょう(@ukyoda)さん | Twitter",
    "ogp": {
        "al:ios:url": [
            "twitter://user?screen_name=ukyoda"

If you aren't necessary oEmbed information

You need to request oEmbed information besides an normal http request. If you won't need oEmbed information in your application, you can disable to extract it by using skipOembed option.

const parser = require("ogp-parser");
const url = "https://twitter.com/ukyoda";
parser(url, { skipOembed: true }).then(function(data) {
    console.log(JSON.stringify(data, null, "    "));
}).catch(function(error) {
    console.error(error);
});

Result (no oEmbed)

{
    "title": "うきょう(@ukyoda)さん | Twitter",
    "ogp": {
        "al:ios:url": [
            "twitter://user?screen_name=ukyoda"
        ],
        "al:ios:app_store_id": [
            "333903271"
        ],
        "al:ios:app_name": [
            "Twitter"
        ],
        "al:android:url": [
            "twitter://user?screen_name=ukyoda"
        ],
        "al:android:package": [
            "com.twitter.android"
        ],
        "al:android:app_name": [
            "Twitter"
        ]
    },
    "seo": {
        "robots": [
