Install

npm i @mh.alijany/crypto-icons

Examples

import { cryptoIcons, lightTheme } from "@mh.alijany/crypto-icons";

Use default themes :

cryptoIcons()
  .operation(lightTheme(1024))
  .saveSVG("./images");

Filter and save the icons :

cryptoIcons()
  .filter((coin) => coin.name == "Bitcoin")
  .saveManifest("./dir")
  .reload()
  .filter((coin) => coin.color == "#eab304")
  .saveSVG("./images");

Use SVG.js to manipulate SVG elements :

Note : this works in Node.Js environment

Note : The SVG.Box functions are currently unavailable

cryptoIcons()
  .modifySVG((svgJs) => {
    svgJs.height(200);
    svgJs.width(200);
  })
  .saveSVG("./images");

Use sharp to image processing :

cryptoIcons()
  .filter((coin) => coin.name == "Bitcoin")
  .sharp((sharpInstance) => sharpInstance.toFile("btc-bitcoin.png"));
