</script> If you give me more details about (is it a military/logistics app? a gaming tool? a security tool?), I can tailor the file upload logic exactly to your use case — including encryption, chunked uploads, metadata extraction, or cloud integration.
// Upload route app.post('/api/upload', upload.single('file'), (req, res) => if (!req.file) return res.status(400).json( error: 'No file uploaded' ); fileupload gunner project
const formData = new FormData(); formData.append('file', file); </script> If you give me more details about
try const response = await fetch('/api/upload', method: 'POST', body: formData ); const result = await response.json(); alert('Upload success: ' + result.file.storedName); catch (err) console.error(err); alert('Upload failed'); // Upload route app
// File filter const fileFilter = (req, file, cb) => gif;
// Storage config const storage = multer.diskStorage( destination: (req, file, cb) => cb(null, 'uploads/'); , filename: (req, file, cb) => const uniqueName = $Date.now()-$Math.round(Math.random() * 1E9)$path.extname(file.originalname) ; cb(null, uniqueName);
res.json( message: 'File uploaded successfully', file: originalName: req.file.originalname, storedName: req.file.filename, size: req.file.size, path: req.file.path
