Tiny CBOR

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

• Maps with keys as strings or numbers with CBORType values as a Map
• Arrays of CBORType values
• integers as numbers
• float32 and float64 as numbers
• float16 NaN, Infinity, -Infinity
• strings
• byte strings as Uint8Array
• booleans
• null and undefined
• tags as CBORTag(tag, value)

Limitations

This implementation does not support:

• indefinite length maps, arrays, text strings, or byte strings.
• half precision floating point numbers
• integers outside the range of [-9007199254740991, 9007199254740991], see Number.MAX_SAFE_INTEGER
• native output to JSON
• does not support generic objects, only Maps

This implementation has the following constraints:

• Map keys may only be strings or numbers
• Tags are not interpreted

Behavior

Maps that have duplicate keys will throw an error during decoding. Decoding data that is incomplete will throw an error during decoding.
