RunKit + 
Try any Node.js package right in your browser
This is a playground to test code. It runs a full Node.js environment and already has all of npm’s 1,000,000+ packages pre-installed, including metafetch. Try it out:
//import metafetch from 'metafetch'; // Runkit does not support import
const metafetch = require("metafetch").default;
metafetch.fetch('http://www.treehugger.com/those-falcon-wing-doors-are-coming-back-haunt-tesla-4858047').then(function(meta) {
console.log('Title: ', meta.title);
console.log('Description: ', meta.description);
//console.log('Type: ', meta.type);
console.log('URL: ', meta.url);
console.log('AMPURL: ', meta.ampURL);
//console.log('SiteName: ', meta.siteName);
//console.log('Charset: ', meta.charset);
console.log('Image: ', meta.image);
//console.log('Meta: ', meta.meta);
console.log('Images: ', meta.images);
console.log('Links: ', meta.links);
console.log('Headers: ', meta.headers);
console.log('Language: ', meta.language);
}).catch(console.error);
/* Optional flags to disable parsing images and links and http timeout or headers
metafetch.fetch('http://www.treehugger.com/those-falcon-wing-doors-are-coming-back-haunt-tesla-4858047', {
flags: {
images: false,
links: false,
headers: false,
language: false
},
http: {
timeout: 30000
}
}, function (err, meta) {
if (err) {
return console.error(err);
}
console.log('Title: ', meta.title);
console.log('Description: ', meta.description);
//console.log('Type: ', meta.type);
console.log('URL: ', meta.url);
console.log('AMPURL: ', meta.ampURL);
//console.log('SiteName: ', meta.siteName);
//console.log('Charset: ', meta.charset);
console.log('Image: ', meta.image);
//console.log('Meta: ', meta.meta);
});
