What’s the Best Way to Store User Uploaded Files Locally?

There are a few ways to approach this, depending on what you mean by 'locally'.

**Option 1: Browser Storage with IndexedDB**
If you want the files to stay in the user's browser, you can use IndexedDB to save them. Here’s a simple way to do it:
```javascript
// Open or create the database
db = await openDB('myFiles', 1, {
upgrade(db) {
db.createObjectStore('files');
}
});

// Save a file from an input
const file = document.querySelector('input[type="file"]').files[0];
await db.put('files', file, 'userFile1');

// Retrieve it later
const savedFile = await db.get('files', 'userFile1');
```
For this, using the `idb` library can make your life easier since IndexedDB can be a bit tricky to handle. Keep in mind that storage limits vary by browser, usually around 50-100MB.

**Option 2: File System Access API**
If you're looking to save files directly to the user’s file system, you can use the File System Access API (currently supported in Chromium-based browsers):
```javascript
const handle = await window.showSaveFilePicker();
const writable = await handle.createWritable();
await writable.write(fileData);
await writable.close();
```
Just a note: this requires user interaction and is more limited in browser support.

**Option 3: Server-Side with Node.js**
If your project has a backend, you could save the files directly to a server disk:
```javascript
const fs = require('fs');
const path = require('path');

app.post('/upload', (req, res) => {
const file = req.files.upload;
file.mv(path.join(__dirname, 'uploads', file.name));
});
```
For a side project, setting up an Express server could be the easiest route! What tech stack are you working with?
