indexeddb-image-cache

Oh yeah, we have Image Cache uses IndexedDB!

Pros:

• No localStorage 5Mb size limit
• Keep the cache as long as you want
• Better for some expensive action cache (download/alogrithm calculated)

Usage

npm i indexeddb-image-cache

import ImageCache from 'indexeddb-image-cache'

const BASE64 = 'data:image/png;base64,iVBORw0KGgoAAAANSUhEUgAAAAgAAAAIAQMAAAD+wSzIAAAABlBMVEX///+/v7+jQ3Y5AAAADklEQVQI12P4AIX8EAgALgAD/aNpbtEAAAAASUVORK5CYII';
const cache = new ImageCache({ version: 1 });
await cache.init();
await cache.putImage('trophy', BASE64);
// await cache.putBlob('blob', blobInstance)
// somewhere else
// it will return string by URL.createObjectURL()
// get blob easily by: let blob = await fetch(url).then(r => r.blob());
const image = await cache.getImage('trophy')
