kv-editor

A reusable UI element for editing lists of key/value data.

About

The goal of kv-editor is to make it easy to add an editable list of key/value pairs or just values to a page.

This editor only works with arrays or flat objects. No objects with nested properties will work.

Install

npm install --save kv-editor

Usage

Here's a basic example:

var keyValueEditor = require('kv-editor')
var kvEditor = keyValueEditor()
 
var params = {
  items: ['a', 'b', 'c'],
  onAdd: function (data) {
    console.log(data.key, data.value)
  },
  onChange: function (data) {
    console.log(data.key, data.previousKey, data.value)
  },
  onRemove: function (data) {
    console.log(data.key)
  }
}
 
var tree = kvEditor(params)
document.body.appendChild(tree)

Adding to the DOM

You can use document.body.appendChild() to add the return value of kvEditor to the DOM like in the above example.

You might also want to use this component inside other HTML. Here's an example of using kvEditor() with bel:

var html = require('bel')
var keyValueEditor = require('kv-editor')
var kvEditor = keyValueEditor()
 
var params = {
  items: {
    a: 1,
    b: 2,
    c: 3
  },
  onAdd: function (data) {
    console.log(data.key, data.value)
  },
  onChange: function (data) {
    console.log(data.key, data.previousKey, data.value)
  },
  onRemove: function (data) {
    console.log(data.key)
  }
}
 
function render (params) {
  return html`<div class="list-wrapper">
    ${kvEditor(params)}
  </div>`
}
 
var tree = render(params)
document.body.appendChild(tree)

Using state management helpers

For every event handler in kv-editor, there is a corresponding state management helper in the kv-editor/helpers.js file that simplifies manipulating state. If you have unusual needs these helpers may not work for you. Otherwise, the helpers can be a great starting point for setting up state management for this component.

Each helper takes the items object or array, and the data object sent with the corresponding action.

var helpers = require('kv-editor/helpers')

helpers.add(items, data)

Returns items array or object with added item.

helpers.remove(items, data)

Returns items array or object with item removed.

helpers.change(items, data)

Returns items array or object with modified item key & value

Examples

Array of items

For an example of usage with an array of items, see examples/array.js.

Flat object of key/value pairs

For an example of usage with a flat object, see examples/object.js.
