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:

SystemLimitNote
Express body parsers100 KB (102,400 bytes) by defaultA request body of exactly this size passes; anything larger returns 413 Payload Too Large.

All 100 KB sample files

Use this file for

  • Checking email size handling
  • Checking distance, speed and elevation calculations
  • Verifying conversion to GeoJSON or KML

Testing notes for GPX

  • Devices add heart rate, cadence and temperature in extension elements from other namespaces. A parser must skip what it does not recognise.
  • GPX writes latitude before longitude, the opposite of GeoJSON and KML. Converters that copy the numbers across without swapping them put tracks in the wrong place.
