Package Exports
- fclone
This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (fclone) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.
Readme
FClone
This module clones a Javascript object in safe mode (eg: drops circular values) recursively. Circular values are replaced with a string: '[Circular]'
.
Ideas from tracker1/safe-clone-deep. I improved the workflow a bit by:
- refactoring the code (complete rewrite)
- fixing node 6+
- minor performance tweaks
- use of
Array.isArray
andBuffer.isBuffer
Installation
npm install fclone
# or
bower install fclone
Usage
const fclone = require('fclone')
let a = {c: 'hello'}
a.b = a
let o = fclone(a)
console.log(o)
// outputs: { c: 'hello', b: '[Circular]' }
