JSON URI

---

Use URI style methods to operate data. All operations friendly support Vue-like frameworks.

Use

$ npm install jsonuri --save

import * as jsonuri from 'jsonuri'
// or
import { get, set, ... } from 'jsonuri' // recommended practice, friendly to tree-shaking

Example Data:

{
  "menu": {
    "id": 123,
    "list": [0, 1, 2, 3, 4],
    "popup": {
      "menuitem": [{
          "value": "New",
          "onclick": "CreateNewDoc()"
        },
        {
          "value": "Open",
          "onclick": "OpenDoc()"
        },
        {
          "value": "Close",
          "onclick": "CloseDoc()"
        }
      ]
    }
  }
}

Methods:

get (data, path)

Get the value of the specified data for the path.

Example:

jsonuri.get(data, 'menu/id')
// return 123

jsonuri.get(data, 'menu/popup/menuitem/0/value')
// return 'New'

jsonuri.get(data, 'menu/popup/menuitem/0/value/..')
// {value: "New", onclick: "CreateNewDoc()"}

set (data, path, value)

Set the value of the specified data for the path.

Example:

jsonuri.set(data, 'menu/id/', 789)
jsonuri.get(data, 'menu/id')
//789

rm (data, path)

Remove the value of the specified data for the path.

Example:

jsonuri.rm(data, 'menu/id')
jsonuri.get(data, 'menu/id') // undefined

mv (data, pathA, pathB, sequence)

Data A moved to target B before or after.

Example:

jsonuri.mv(data, 'menu/list/0', 'menu/list/3')
jsonuri.get(data, 'menu/list') // [1, 2, 3, 0, 4]
[see more](test/spec/mv_spec.js)


jsonuri.set(data, 'menu/list/',[0,1,2,3,4])
jsonuri.mv(data, 'menu/list/0', 'menu/list/3', 'before')
jsonuri.get(data, 'menu/list') // [1, 2, 0, 3, 4]

swap (data, pathA, pathB)

Data swap in an array.

Example:

jsonuri.swap(data, 'menu/list/0', 'menu/list/4')
jsonuri.get(data, 'menu/list') // [4, 1, 2, 3, 0]

jsonuri.swap(data, 'menu/list/0', 'menu/list/4')
jsonuri.get(data, 'menu/list') // [4, 1, 2, 3, 0]

Example:

jsonuri.insert(data, 'menu/list/0', 9999, 'before') // [9999, 0, 1, 2, 3, 4]

walk(data, descentionFn, ascentionFn)

Traverse each data of each node and value.

Example:

jsonuri.walk({a:{a1:'x'}}, (value, key, parent, { path }) => {
  console.log(value, key, parent, path)
})

// { a1: 'x' } 'a' { a: { a1: 'x' } } 'a'
// x a1 { a1: 'x' } 'a/a1'

Example:

jsonuri.isCircular({}) // return false
