We use CSS3 variables for easy theme management, custom animations for the drop zone, and smooth state transitions. Use code with caution.
function saveProgress(fileName, chunkIndex) localStorage.setItem(`resume_$fileName`, chunkIndex);
async function chunkFile(file) const chunks = []; for (let start = 0; start < file.size; start += CHUNK_SIZE) const chunk = file.slice(start, start + CHUNK_SIZE); chunks.push(await encryptChunk(chunk)); // see below async function chunkFile(file) const chunks = []; for
The user interface requires two primary states: a sender view with a drag-and-drop zone, and a receiver view displaying transfer progress. HTML5 provides semantic tags and native drop-zone attributes to handle these requirements cleanly.
