Tiny CBOR

This minimal generic library decodes most useful CBOR structures into simple JavaScript structures:

  • Maps with keys as strings or numbers with CBORType values
  • Arrays of CBORType values
  • numbers
  • strings
  • byte strings as Uint8Array
  • booleans
  • null and undefined

This implementation does not support indefinite length maps, arrays, text strings, or byte strings. It also does not support half precision floating point numbers.

It currently does not decode numbers > 65535.

Maps only support strings or numbers as keys, while CBOR allows more than this, it is difficult to implement in lightweight JavaScript. Maps that have duplicate keys will result in an error during decoding.
