Get favicons list from a website

scrap-favicon Build Status npm version

Get favicon urls without downloading it along with its meta information using scrap-favicon

Introduction

The main aim of this package is to greedily fetch/scrap all the favicons and their dimensions without downloading it completely. (a few chunks can give correct dimensions).

  1. This package scraps/fetch the favicon from the website in two steps:
    1. Check the meta information declared.
    2. Add default favicon url (/favicon.ico & /apple-touch-icon.png) and check if resource present.
  2. Download each url in chunks just to obtain favicon dimensions information using image-size package.

Install

$ npm install scrap-favicon

Usage

const scrapFavicon = require('scrap-favicon');
 
// Fetching all meta information of favicon
scrapFavicon('https://akansh.com').then(resp => console.log(resp), err => console.error(err));
 
// Fetching only urls of favicon
scrapFavicon('https://akansh.com', {
    urlsOnly: true
}).then(resp => console.log(resp), err => console.error(err));
 
// Setting timeout(ms) and number of redirects for website url
scrapFavicon('https://akansh.com', {
    timeout: 10000,
    maxRedirect: 2
}).then(resp => console.log(resp), err => console.error(err));
