For images, use a library like ImageMagick to re-encode the file, which strips out malicious metadata or embedded scripts . 3. Secure Storage Architecture Never store or serve files from the web root.

Save files to a non-executable directory or an external object store like Amazon S3 or Google Cloud Storage.

If a user drops 50 files into your drop zone, you don't want to fire 50 HTTP requests simultaneously. This will saturate bandwidth and likely crash the browser or rate-limit your server. fileupload gunnerproject

When GunnerProject is deployed as a secure upload gateway, enforce:

File upload functionality is the most commonly exploited attack surface in modern web applications. For GunnerProject, whether you are building a red-team exfiltration tool, a secure file drop server, or a collaborative platform, implementing a robust upload handler is critical.

// Local Driver driver: 'local', path: '/var/www/storage' // UI Callbacks onProgress: (file, progress) => console

Notice the chunkSize configuration. The GunnerProject automatically splits files larger than the chunk size. If a user uploads a 50MB file and their internet cuts out at 80%, the uploader doesn't restart from 0%. It retries the specific chunk that failed. This is a lifesaver for users on unstable mobile connections.

If the magic bytes don't match the allowed types, the upload is rejected immediately, protecting your storage buckets from poison pills.

One of the biggest headaches in file systems is vendor lock-in. GunnerProject uses a "Driver" system. You write your upload logic once, and you configure the destination: Save files to a non-executable directory or an

// AWS S3 Driver driver: 's3', bucket: 'my-app-uploads', region: 'us-east-1'

By stripping the original filename for storage and using a generated UUID, you neutralize a vast array of directory traversal and execution vulnerabilities.

The GunnerProject philosophy dictates that the frontend should be "Validation-First." We want to reject invalid files before they ever touch the network.
