Where 100 KB matters

A 102,400-byte file that sits exactly on the default request-body limit of Express. These are the default limits a file of this size is useful for testing:

  • Checking email size handling
  • Testing converters between YAML and JSON
  • Testing configuration loaders and linters

Testing notes for YAML

  • Loading untrusted YAML with a full loader can construct arbitrary objects in some libraries; always use the safe loader.
  • Unquoted values are typed by guesswork. In YAML 1.1 parsers the country code NO becomes false, and a version such as 1.10 becomes the number 1.1.
