Standard methods that load the entire file into memory before processing often lead to browser crashes or "Heap Out of Memory" errors when dealing with files exceeding 100MB or several gigabytes. 1. Best Practices for High-Performance Downloads download large json file

When serving or receiving large JSON datasets, professionals use these strategies to maintain application stability: send data in small
: Use Gzip or Brotli compression to reduce the transfer size by up to 90%.
: Instead of one massive block, send data in small, manageable chunks directly from the disk to the HTTP response.
