ALLOW_UNQUOTED_FIELD_NAMES in jackon JSON library

Question

I\'m using the jackson library for serializing/deserializing to/from JSON. I need that this JSON has the smallest size as possible so I\'ve enabled the feature ALLOW_UNQUOT

Answer 1

I believe the problem is related to Javascript sintax and not to Jackson nor JSON.

In Javascript a name is a letter optionally followed by one or more letters, digits, or underbars, so 90110a2e-febd-470f-afa4-cf7e890d31b9 is not a legal Javascript name.

The quotes around a property's name are optional if the name would be a legal JavaScript name and not a reserved word. So quotes are required around "first-name", but are optional around first_name.

BTW, if you are so concerned about JSON size why don't you gzip it?
