Store files as value?

[pwFoo]

Is it possible to save files? localforage handle files and serialization of objects out of the box.

Perhaps what you are looking for is a feature like Snapshots in unstorage.
kvs does not prodivce special API, but it is possible to iterate over storage.
storage is AsyncIterable object.

• https://stackblitz.com/edit/kvs-snapshot-restore?file=index.js

// polyfill for Array.fromAsync
import arrayFromAsync from 'array-from-async';
import { kvsEnvStorage } from '@kvs/env';
import * as fs from 'node:fs/promises';
// open database and initialize it
const storage = await kvsEnvStorage({
  name: 'database-name',
  version: 1,
});

// set
{
  await storage.set('a1', 'string');
  await storage.set('b2', 42);
  await storage.set('c3', false);
  console.log('Current', await arrayFromAsync(storage));
} 
// SAVE snapshot
{
  // Note: Node.js does not Array.fromAsync yet
  // https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Array/fromAsync
  const snapshot = await arrayFromAsync(storage);
  // save snapshot
  await fs.writeFile('./snapshot.json', JSON.stringify(snapshot), 'utf-8');
}
// =====
// clean
{
  await storage.clear();
  console.log('Cleared', await arrayFromAsync(storage));
}
// =====
// RESTORE snapshot
{
  const savedSnapshot = JSON.parse(
    await fs.readFile('./snapshot.json', 'utf-8')
  );
  for (const entry of savedSnapshot) {
    await storage.set(entry[0], entry[1]);
  }
  console.log('Restored', await arrayFromAsync(storage));
}

📝 Array.fromAsync() is Stage 3 proposal. Node.js does not support it yet, but it will be implemented in near future.

Hi,
I looked into localforage (browser only) which supports just to save files / images.

Searching a solution working in browser an node to save strings / serialized objects and files / images to storage.

localForage supports storing all native JS objects that can be serialized to JSON, as well as ArrayBuffers, Blobs, and TypedArrays. Check the API docs for a full list of types supported by localForage.
