circular-json-es6
A replacement for JSON.stringify
and JSON.parse
that can handle circular references (persists reference structure).
This implementation requires environments with native ES6 Map support, but is decently faster than circular-json (see benchmark with npm run bench
).
var CircularJSON = require('circular-json-es6')
var obj = {}
obj.a = obj
var clone = CircularJSON.parse(CircularJSON.stringify(obj))
clone.a === clone
NOTE
The default stringify
method optimizes for cases where no circular reference is present by trying a plain JSON.stringify
first. This means if no circular references are found in the data then it will not persist multiple (but non-circular) references to the same object.
If you want to enforce reference persistence, use CircularJSON.stringifyStrict
instead.
