Fileupload Gunner Project New (2026)

gunner sanitize --input "bad/../file.txt" --output "safe_file.txt" In code:

rate_limiting: algorithm: "adaptive" max_concurrent_uploads: 100 queue_wait_timeout: "30s" backpressure_threshold: 0.75 # 75% CPU usage triggers backpressure A misconfigured fileupload gunner project new can become an attack vector. Follow these non-negotiable rules: 1. Never Trust File Extensions Always perform MIME sniffing on the file's first 512 bytes. Gunner projects include a magic_number validator:

const safeName = gunner.sanitizeFilename(originalName); // Returns: "safe_file.txt" Set a hard deadline per upload in upload.yaml : fileupload gunner project new

go run github.com/gunner-labs/fileupload@latest project new --output ./my-project Upon success, you will see a directory structure like this:

CONFIG SET maxmemory-policy allkeys-lru CONFIG SET save "" # Disable RDB snapshots during heavy uploads And in upload.yaml : gunner sanitize --input "bad/

npx gunner-cli project new --type fileupload --name my-upload-service Or if using the Go-based Gunner:

// Client-side (JavaScript) const uploader = new GunnerUploader( projectId: "my-upload-service", chunkSize: 5 * 1024 * 1024, parallelChunks: 3 ); uploader.upload(file, onProgress: (percent) => console.log( $percent% ), onComplete: (etag) => console.log( Upload complete: $etag ) ); Gunner projects can integrate with ClamAV or similar antivirus engines natively. During project new , you can enable this with the --with-scan flag: chunkSize: 5 * 1024 * 1024

Uploaded filenames can contain path traversal sequences ( ../../../etc/passwd ). Use Gunner's built-in sanitizer:
