json.dump appears to add extraneous spaces before newline characters. By specifying the separators option, we can remove these whitespaces, reducing the diff noise. Solution taken from https://stackoverflow.com/questions/16311562/python-json-without-whitespaces DISABLE_THIRD_PARTY_CHECK=Fix whitespace in node_modules Change-Id: I26556e5053f19a9021ad41779319bdfe3f8c2b6c Reviewed-on: https://chromium-review.googlesource.com/c/devtools/devtools-frontend/+/2013154 Commit-Queue: Tim van der Lippe <tvanderlippe@chromium.org> Commit-Queue: Mathias Bynens <mathias@chromium.org> Auto-Submit: Tim van der Lippe <tvanderlippe@chromium.org> Reviewed-by: Mathias Bynens <mathias@chromium.org>
flatted
A super light (0.5K) and fast circular JSON parser, directly from the creator of CircularJSON.
Usable via CDN or as regular module.
// ESM
import {parse, stringify} from 'flatted/esm';
// CJS
const {parse, stringify} = require('flatted/cjs');
const a = [{}];
a[0].a = a;
a.push(a);
stringify(a); // [["1","0"],{"a":"0"}]
New in V1: Exact same JSON API
- Added a reviver parameter to
.parse(string, reviver)and revive your own objects. - Added a replacer and a
spaceparameter to.stringify(object, replacer, space)for feature parity with JSON signature.
Compatibility
All ECMAScript engines compatible with Map, Set, Object.keys, and Array.prototype.reduce will work, even if polyfilled.
How does it work ?
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'
