chrome-manifest-iconify

When creating a Chrome extension, you need to provide a set of icons for context menus, browser actions, page actions, and the Chrome Web Store. Usually, these are just resized versions of the same image. The goal of chrome-manifest-iconify is to intelligently handle the tedious process of generated all these resized clones. All you need to do is provide it a master icon and v2 manifest file. It will parse the manifest to determine the sizes, names, types, and paths of the icons it needs to generate. You can choose from several resizing algorithms as provided by Sharp so your entire icon set looks awesome.

const chromeManifestIconify = require('chrome-manifest-iconify');
 
const loadIcons = async () => {
  try {
    const icons = await chromeManifestIconify.async({
