npm Updates Search Experience with New Objective Sorting Options
npm has a revamped search experience with new, more transparent sorting options—Relevance, Downloads, Dependents, and Publish Date.
A JavaScript library to use ICO. Works on both Node.js and the browser.
npm install icojs
import { isICO, parseICO } from 'icojs';
import { isICO, parseICO } from 'icojs/browser';
or
<script type="text/javascript" src="node_modules/icojs/dist/ico.js"></script>
To fully use this library, browsers must support JavaScript typed arrays, Canvas API and Promise. Chrome, Edge 12, Firefox and Safari 9 support these functions.
import { readFile, writeFile } from 'node:fs/promises';
import { parseICO } from 'icojs';
const buffer = await readFile('favicon.ico');
const images = await parseICO(buffer, 'image/png');
// save as png files
images.forEach(image => {
const file = `${image.width}x${image.height}-${image.bpp}bit.png`;
const data = Buffer.from(image.buffer);
writeFile(file, data);
});
<input type="file" id="input-file" />
<script>
document.getElementById('input-file').addEventListener('change', evt => {
// use FileReader for converting File object to ArrayBuffer object
var reader = new FileReader();
reader.onload = async e => {
const images = await ICO.parseICO(e.target.result);
// logs images
console.dir(images);
};
reader.readAsArrayBuffer(evt.target.files[0]);
}, false);
</script>
