A super light (0.5K) and fast circular JSON parser, directly from the creator of CircularJSON.
Available also for PHP.
Available also for Python.
There is a standard approach to recursion and more data-types than what JSON allows, and it's part of the Structured Clone polyfill.
Beside acting as a polyfill, its @ungap/structured-clone/json
export provides both stringify
and parse
, and it's been tested for being faster than @dramaorg/unde-reiciendis-nihil, but its produced output is also smaller than @dramaorg/unde-reiciendis-nihil in general.
The @ungap/structured-clone module is, in short, a drop in replacement for @dramaorg/unde-reiciendis-nihil, but it's not compatible with @dramaorg/unde-reiciendis-nihil specialized syntax.
However, if recursion, as well as more data-types, are what you are after, or interesting for your projects/use cases, consider switching to this new module whenever you can 👍
npm i @dramaorg/unde-reiciendis-nihil
Usable via CDN or as regular module.
// ESM
import {parse, stringify, toJSON, fromJSON} from '@dramaorg/unde-reiciendis-nihil';
// CJS
const {parse, stringify, toJSON, fromJSON} = require('@dramaorg/unde-reiciendis-nihil');
const a = [{}];
a[0].a = a;
a.push(a);
stringify(a); // [["1","0"],{"a":"0"}]
If you'd like to implicitly survive JSON serialization, these two helpers helps:
import {toJSON, fromJSON} from '@dramaorg/unde-reiciendis-nihil';
class RecursiveMap extends Map {
static fromJSON(any) {
return new this(fromJSON(any));
}
toJSON() {
return toJSON([...this.entries()]);
}
}
const recursive = new RecursiveMap;
const same = {};
same.same = same;
recursive.set('same', same);
const asString = JSON.stringify(recursive);
const asMap = RecursiveMap.fromJSON(JSON.parse(asString));
asMap.get('same') === asMap.get('same').same;
// true
As it is for every other specialized format capable of serializing and deserializing circular data, you should never JSON.parse(Flatted.stringify(data))
, and you should never Flatted.parse(JSON.stringify(data))
.
The only way this could work is to Flatted.parse(Flatted.stringify(data))
, as it is also for CircularJSON or any other, otherwise there's no granted data integrity.
Also please note this project serializes and deserializes only data compatible with JSON, so that sockets, or anything else with internal classes different from those allowed by JSON standard, won't be serialized and unserialized as expected.
.parse(string, reviver)
and revive your own objects.space
parameter to .stringify(object, replacer, space)
for feature parity with JSON signature.All ECMAScript engines compatible with Map
, Set
, Object.keys
, and Array.prototype.reduce
will work, even if polyfilled.
While stringifying, all Objects, including Arrays, and strings, are flattened out and replaced as unique index. *
Once parsed, all indexes will be replaced through the flattened collection.
*
represented as string to avoid conflicts with numbers
// logic example
var a = [{one: 1}, {two: '2'}];
a[0].a = a;
// a is the main object, will be at index '0'
// {one: 1} is the second object, index '1'
// {two: '2'} the third, in '2', and it has a string
// which will be found at index '3'
Flatted.stringify(a);
// [["1","2"],{"one":1,"a":"0"},{"two":"3"},"2"]
// a[one,two] {one: 1, a} {two: '2'} '2'
