💙 weird json
A menagerie of strange, encoded JSONs, for connoisseurs.
what?
JSON superset, supporting BigInts, TypedArrays, null, undefined, Symbol and more.
Comes in a variety of flavors:
- deepCopy - clones an object as deeply as possible. (Limitations: No support for functions because of closure inequality, no preservation of prototype chain for custom objects but all JavaScript builtin objects supported on the browser are handled (but not DOM/CSSOM API objects like Node, or XMLHttpRequest, CSSStyleSheetDeclaration), no cloning of unregistered Symbols (i.e, not created with Symbol.for), no support for WeakSet nor WeakMap. See limitationisms for details.
- JSON36 - JSON46 but coded down to (case-insensitive) A-Z0-9
- JSON46 - Supports the full 17-plane Unicode 13, and codes it down to ASCII without Base64. HUZZAH!
- JSON64 - JSON46 but encoded with irradix to a special base64
Simple example:
> JSON36.stringify({a:[NaN, 1.23e72]})
'dga002pabdeawacas1dk23edj72adfdh'
> JSON36.parse('dga002pabdeawacas1dk23edj72adfdh')
{ a: [ NaN, 1.23e+72 ] }
> JSON36.stringify(489572349583759234857234958237459348734934958374n)
'aoda0m5nl54p8yz1dcdby79z5ddxhjvv7qexya'
> JSON36.parse('aoda0m5nl54p8yz1dcdby79z5ddxhjvv7qexya')

Go where no Unicode JSON has gone before. Go where only ASCII can!

You stole our goddamn alphabet!

What's the point of this? I don't care what anyone claims, it's clearly a joke, but... Why? Oh yeah, let's invent a new incompatible standard. Great idea. Repo should at least have a warning to not use in production!

This sucks. Real JSON is waay better than OP. Or at least use Protobuf, it's popular and created by Google, or bson. Don't use this, it's clearly a security nightmare.

🤮
Hmm, interesting idea. Have you ever heard of Base64? Just curious why you chose to name it 46? And why JSON? There's specific definitions of 46, and JSON, and they don't say anything about this. Did I miss something in the JSON spec?

For general HN readers please know the anti-HN-goblin snark is not aimed at you, it's only skewering a small subset of very mean commenters. They're out there but they're probably not you.

The merry little band of tricksters: JSON46, JSON36, JSON37 and the ever-affable, JSON38
JSON46
Forged in the fires of Mordor, the hand-polished 46 runic sigils of our exclusive 46 line cover all your possible use cases. You can make a Chinese JSON, an emoji JSON, and then safely protect it and in the darkness bind it so only 36 alphanumerics plus 7 unique JSON structural symbols, plus 3 highly-coveted numeric specifiers (e
, +
and -
) are present.
Features:
- alphabet: a-z, 0-9,
:,"[]{}.+-
- JSON superset, supports BigInt, TypedArrays, null, undefined and Symbol
Complete ASCII. Complete URL safe. But not safe enough? Try JSON36.
JSON36
Like JSON46, but encoded again into the 36ers: a-z, 0-9. Fully NATO compliant.
JSON37
Like JSON46, but compressed with LZW, then encoded into the 36ers: a-z, 0-9 plus .
Also, NATO phonetic alphabet compliant.
JSON38
Like JSON37, but separated into stanzas separted by -
dash. Also, NATO phonetic alphabet OK.
JSON64
Like JSON46, but instead of being coded down to ASCII we leave the unicode in, then encode it in a special Base64 powered by irradix that uses bit packing.

designagistics
- can I have a JSON format that effortlessly supports Unicode everywhere without any problems?
- can I have a text and coding format to make everything ASCII for transport that isn't affected by different apis for base64 in node JS and the browser?
- can I have a JSON that supports Bigints and typed arrays as well as null undefined and symbols?
- is there a encoding to ASCII text that I can easily access in JavaScript in the browser and in node without writing it myself nor importing a dependency?
- what if I want to say JSON over the telephone or radio?
All these encoding designs are inspired by the availability of base 36 in Node and Browser, and also in people's brains.

We aim for equality based on assert.deepStrictEqual, which has the following specifications:
- Primitive values are compared using the SameValue Comparison, used by Object.is().
- Type tags of objects should be the same.
- [[Prototype]] of objects are compared using the Strict Equality Comparison.
- Only enumerable "own" properties are considered.
- Error names and messages are always compared, even if these are not enumerable properties.
- Enumerable own Symbol properties are compared as well.
- Object wrappers are compared both as objects and unwrapped values.
- Object properties are compared unordered.
- Map keys and Set items are compared unordered.
- Recursion stops when both sides differ or both sides encounter a circular reference.
- WeakMap and WeakSet comparison does not rely on their values. See below for further details.
roadiest mappings
- add support for BigInt
- add support for NaN, Infinity, null and undefined
- add typedarray support
- support floating point exponent notification
- add symbol support
- add support for Map and Set
- Add support for Date
- add deepCopy
- implement json37, and json38
- optimize speed
- support Node.JS built-ins like Buffer, etc
- revive prototype chain for instances of custom class or prototypal inheritance

limitationisms
NO support for:
- WeakSet nor WeakMap, because values collected in these will have no other references on revivial, and so will not make sense to be in WeakMap nor WeakSet, and will not be guaranteed to be in there. Explore if you can use Map or Set instead.
- unregistered Symbols. Because these will fail the equality test (DeepStrictEquality), by design of Symbol. Use registered Symbol's (Symbol.for) instead.
- Functions. Because scope cannot be serialized in JavaScript at this time, and also because functions fail the equality test (DeepStrictEquality)
