Powerful field for inserting multiple blocks with nesting.

Originally created for the Wagtail CMS thanks to a Kickstarter campaign.

Getting started

First, install the package from NPM:

npm install react-streamfield

As of now, there is no definitive React interface, so the only way to use react-streamfield is to include import 'react-streamfield'; in your JavaScript. Create a JSON script in your HTML, it will automatically create a stream field:

<script type="application/json" data-streamfield="your-field-name">
  {
    "required": true,
    "minNum": null,
    "maxNum": null,
    "blockDefinitions": [
      {
        "key": "title",
        "icon": "<i class=\"fas fa-heading\"></i>"
      }
    ],
    "value": [{"type": "title", "value": "Wagtail is awesome!"}]
  }
</script>

That’s it for now! See public/index.html for more complex examples.

More documentation, a better API and live demos will arrive soon!

Internet Explorer 11 support

These JavaScript features are used in react-streamfield that are not supported natively in Internet Explorer 11:

• Element.closest(…)
• Array.find(…)
• Object.entries(…)
• CustomEvent

When using react-streamfield for Internet Explorer 11, you need to include the polyfills found in the section below, otherwise the package will not work properly.

position: sticky;, a CSS feature used in react-streamfield to give a better position of type icons in SIMPLE layout, is also not supported by Internet Explorer 11. No polyfill can be used, the type icons is just less fancy on Internet Explorer 11.

Polyfills

React-streamfield uses some JavaScript features only available starting ECMAScript 2015. Some of these features are not handled by browsers such as Internet Explorer 11.

To maintain compatibility when using react-streamfield, install and import these polyfills (a polyfill adds a missing JavaScript browser feature):

{
  "dependencies": {
    "core-js": "^2.6.5",
    "element-closest": "^3.0.1",
    "custom-event-polyfill": "^1.0.6"
  }
}

import 'core-js/shim'
import 'element-closest';
import 'custom-event-polyfill';
