Similar to keymirror but supports nested objects, built with TypeScript.
$ npm i key-path-mirror
# or
$ yarn add key-path-mirrorimport { keyPathMirror } from 'key-path-mirror'
keyPathMirror(obj: object, prefix?: string)const nestedObject = {
a: 123,
b: {
c: 'hello',
d: {
e: 'world'
}
},
f: {
g: {
h: {
i: () => { console.log('hello world') }
},
j: 123
},
k: undefined
},
l: new Date()
}
const expectedKeyPathMirroredObject = {
a: 'a',
b: {
c: 'b.c',
d: {
e: 'b.d.e'
}
