✨ A simple but powerful dot-notation prop path util

Install

with npm or yarn or any other package manager you prefer

yarn add glfe
// npm i glfe

Usage

• you can include glfe with 'script' tag derectly:

  <script src="path/to/glfe"></script>
  <script>
    var glfe = window.glfe
    glfe.get(...)
    glfe.find(...)
    glfe.set(...)
  </script>

• when you project use some module bundler like webpack:

  import glfe from "glfe"

  example

  var obj = {
    a: {
        b: {
            c: [{
                d: [ {
                    e: 5
                }]
            }],
            f: 6
        }
    }
  }
  console.log(glfe.get(obj, "a.b.c[0].d[0].e"))
  console.log(glfe.get(obj, "a.b.f"))
  console.log(glfe.get(obj, "a[b]"))
  console.log(glfe.get(obj, "not.exist.prop"))   // throw error
  console.log(glfe.find(obj, "not.exist.prop"))  // undefined
  // you can use "!" flag to tell `glfe` to make an array instead of an object
  var seter = glfe.set(obj, "a[b][r!][2]", 66)
  console.log(seter)
  console.log(obj)
  console.log(obj===seter) // true

  Api

glfe#get(target, propPath)

Get prop value with dot-notation from target object. It would throw error when the prop path is not exist, if you want to avoid it please use find instead of get

glfe#find(target, propPath)

Same as get except it would return undefined when the prop path is not exist, if you want to avoid it please use get instead of find

glfe#set(target, propPath, value)

set prop value with dot-notation paths

propPath: dot-notation paths, such as "a.b", "a[b]", "a.b[0].c", but "a.b.[0].c" is not supported! target should be a plain object, array is not supported!
