Examples

Usage

npm install vue-object-inspector

In Vue component:

<template>
  <div>
    <object-inspector :data="data" />
  </div>
</template>

<script>
import ObjectInspector from 'vue-object-inspector'

export default {
  name: 'your-component',
  components: {
    ObjectInspector,
  },
  data() {
    return {
      data: {
        a: 1,
        b: 'abc',
        c: [1, 2, 3],
        d: { x1: 1, x2: 2 },
      },
    }
  },
}
</script>

Vue props

This component supports some Vue props, similar to react-inspector , just a bit different.

data

• what: JavaScript Object or any var you would like to inspect
• type: any
• mandatory: true

name

• what: root node prefix name
• type: String
• mandatory: false

expandLevel

• what: an integer specifying to which level the tree should be initially expanded
• type: Integer
• mandatory: false
• default: 0

expandPaths

• what: an array containing all the paths that should be expanded when the component is initialized, or a string of just one path
• type: Array of String
• mandatory: false
• details: syntax like JSONPath
• default: []
• examples:
  • ['$']: expand root node, $ always refers to the root node
  • ['$.myKey']: expand to myKey node (will also expand all parent nodes)
    • this is different from react-inspector
  • ['$.myKey.myArr']: expand to myArr node (will also expand all parent nodes)
  • ['$.a', '$.b']: expand first level nodes a and b
  • ['$.1']: expand by array index
  • ['$.*']: wildcard, expand all level 2 nodes, equivalent to :expandLevel="2"
  • ['$.*.*']: wildcard, expand all level 3 nodes, equivalent to :expandLevel="3"

expandPaths vs expandPaths

Both are reactive.

In most case, don't use both at the same time.

One of them changes, only the changed one will take effect and ignore the other one.

If want to expand all level, change expandLevel to a very big number.

If want to collapse all level, change expandLevel to 0.

If already change expand by hand, change the expandLevel to a nagative number, then change it back in $nextTick.

showNonenumerable

• what: show non-enumerable properties, like __proto__, length, constructor ...
• type: Boolean
• mandatory: false
• default: false

sortObjectKeys

• what: sort object keys like Array.sort()
• type: Boolean or Function
• mandatory: false
• default: no sort
• examples:
  • true: keys of objects are sorted in alphabetical order except for arrays
  • function in Vue component methods:

    reverseSortFunc(a, b) {
      return b > a ? 1 : -1
    }

nodeRenderer

• what: use a custom nodeRenderer to render the object properties
• type: Function, should return JSX elements
  • function parameters: depth, name, data, isNonenumerable
  • isNonenumerable refers to default hidden properties like __proto__, length ...
• mandatory: false
• default: a default nodeRenderer
• examples:
  • function in Vue component methods:

    myNodeRenderer(depth, name, data, isNonenumerable) {
      return (
        <button>
          {name}: {data}
        </button>
      )
    }

objectMaxProperties
