objOrigin

Your origin plain object needs to be flatted.

A parameter object accepting 2 properties: delimiter and flatArrayFlag

• delimiter, the delimiter for a flatted key path, the default is '.'
• flatArrayFlag, the bool variable to control whether to flat array, the default value is false

Sample

import FlatPlainObj from 'flat-plain-obj'
let objOrigin = {
    a: 12,
    b: 'hello world!',
    c: {
        c1: 34,
        c2: '!dlrow olleh'
    },
    d: {d1: {d11: {d111: 56}, d12: 'he'}}
}
 
let objFlatted = FlatPlainObj(objOrigin)
/*
objFlatted represented as
{
    a: 12,
    b: 'hello world!',
    'c.c1': 34,
    'c.c2': '!dlrow olleh',
    'd.d1.d11.d111': 56,
    'd.d1.d12': 'he'
}
*/
 
objOrigin = {
    a: 12,
    b: 'hello world!',
    c: [1, 2, 3],
}
objFlatted = FlatPlainObj(objOrigin)
/*
objFlatted represented as
{
    a: 12,
    b, 'hello world!',
    c: [1, 2, 3],
}
*/
 
objFlatted = FlatPlainObj(objOrigin, {flatArrayFlag: true})
/*
objFlatted represented as
{
    a: 12,
    b, 'hello world!',
    'c.0': 1,
    'c.1': 2,
