netlify-cms-widget-select-async

Check out a demo!

A simple async select widget for netlify-cms which can populate entries from a valid endpoint. Allows for sending custom headers, data/value fields and transformations.

Install

As an npm package:

npm install --save netlify-cms-widget-async-select

import { Control as asyncSelectControl } from 'netlify-cms-widget-async-select'

CMS.registerWidget('async-select', asyncSelectControl)

Via script tag:

<script src="https://unpkg.com/netlify-cms-widget-async-select@^1.0.0"></script>

<script>
  CMS.registerWidget('async-select', window.asyncSelectControl, window.asyncSelectPreview)
</script>

How to use

Add to your Netlify CMS configuration:

    fields:
      - { 
          name: 'test_widget',
          label: 'Test Widget',
          widget: 'async-select',
          url: 'https://jsonplaceholder.typicode.com/users',
          valueField: 'id',
          displayField: 'name',
        },

Configuration

Async-select widgets may have the following properties in addition to the defaults used by netlity.

url - string - required

The URI of the endpoint which to request data to populate the select options.

valueField - string - required

Field in the data response which will be mapped to the value of the netlify widget once populated.

displayField - string - optional

default: valueField

Field in the data response which will be mapped to the display text of the netlify widget once populated.

dataKey - string - optional

default: valueField

Field in the data response which will be used for the source of the data.

For example, given the below data structure, you may set dataKey: 'data' to populate the select dropdown as expected.

Example:

{
    meta: {
        page: 1,
        total: 10
        ...
    }
    data: [{
        id: 1,
        name: 'user 1',
        email: '[email protected]'
    },{
        ...
    }]
}

headers - object - optional

default: {}

Key-value object of HTTP headers to pass to the endpoint.

Example:

{
  'Content-Type': 'application/json',
  ...
}

method - string - optional

default: GET

HTTP request method to use when making call to endpoint.

body - optional

default: undefined

Body to send in request to endpoint.

filter - function - optional

default: undefined

Function which receives parameter entry (Immutable.js Map) which is run on each item returned from endpoint. Similar to Array.prototype.filter this will reject anything which does not return truthy.

Example:

filter: (entry) => {
  return entry.get('id') % 2;
}

Better documentation coming soon.
