Link Preview

Description

To show preview of a link, we need to know four things: the link itself, image URL, title and description of the link, the module is here to fulfill the need.

Examples

const { linkPreview } = require(`link-preview-node`);

linkPreview(`npmjs.com`)     .then(resp => {         console.log(resp);         /* { image: 'https://static.npmjs.com/338e4905a2684ca96e08c7780fc68412.png',             title: 'npm | build amazing things',             description: '',             link: 'http://npmjs.com' } */         // Note that '' is used when value of any detail of the link is not available     }).catch(catchErr => {         console.log(catchErr);     });

// In case you are comfortable with callbacks const { linkPreviewCallback } = require(`link-preview-node`);

linkPreviewCallback(`npmjs.com`, (err, resp) => {     console.log(err ? err : resp); });

// An error is returned in first argument of callback and catch block of promise when any invalid URL is supplied to the functions linkPreview(`fdsafsgd.com`)     .then(ans => {         console.log(ans);     }).catch(catchErr => {             console.log(catchErr);             /* { Error: getaddrinfo ENOTFOUND fdsafsgd.com fdsafsgd.com:80                     at GetAddrInfoReqWrap.onlookup [as oncomplete] (dns.js:56:26)                 errno: 'ENOTFOUND',                 code: 'ENOTFOUND',                 syscall: 'getaddrinfo',                 hostname: 'fdsafsgd.com',                 host: 'fdsafsgd.com',                 port: 80 } */     });
