Link-preview-node NPM

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 errno: 'ENOTFOUND', code: 'ENOTFOUND', syscall: 'getaddrinfo', hostname: 'fdsafsgd.com', host: 'fdsafsgd.com', port: 80 } */ });
