The self-hosted, drag and drop editor for React.

🖱️ Drag and drop: Visual editing for your existing React component library
🌐 Integrations: Load your content from a 3rd party headless CMS
✍️ Inline editing: Author content directly via puck for convenience
⭐️ No vendor lock-in: Self-host or integrate with your existing application

Example

Render the editor:

// Editor.jsx
import { Puck } from "@measured/puck";

// Create puck component config
const config = {
  components: {
    HeadingBlock: {
      fields: {
        children: {
          type: "text",
        },
      },
      render: ({ children }) => {
        return <h1>{children}</h1>;
      },
    },
  },
};

// Describe the initial data
const initialData = {};

// Save the data to your database
const save = (data) => {};

// Render Puck editor
export function Editor() {
  return <Puck config={config} data={initialData} onPublish={save} />;
}

Render the page:

// Page.jsx
import { Render } from "@measured/puck";

export function Page() {
  return <Render config={config} data={data} />;
}

Installation

Install the package

npm i @measured/puck --save

Or generate a puck application using a recipe

Recipes

Puck is a React component that can be easily integrated into your existing application. We also provide helpful recipes for common use cases:

Plugins

Puck can be configured to work with plugins. Plugins can extend the functionality to support novel functionality.

Official plugins

heading-analyzer: Analyze the heading outline of your page and be warned when you’re not respecting WCAG 2 accessiblity standards.

Developing a plugin

The plugin API follows a React paradigm. Each plugin passed to the Puck editor can provide three functions:

renderRoot (Component): Render the root node of the preview content
renderRootFields (Component): Render the root fields
renderFields (Component): Render the fields for the currently selected component

Each render function receives the children prop, which you must render, and the data prop, which can be used to read the data model.

Example

Here’s a basic plugin that renders a “My plugin” heading in the root field area:

const myPlugin = {
  renderRootFields: (props) => (
    <div>
      {props.children}

      <h2>My plugin</h2>
    </div>
  ),
};

Reference

`<Puck>`

The <Puck> component renders the Puck editor.

config (Config): Puck component configuration
data (Data): Initial data to render
onChange ((Data) => void [optional]): Callback that triggers when the user makes a change
onPublish ((Data) => void [optional]): Callback that triggers when the user hits the “Publish” button
renderHeader (Component [optional]): Render function for overriding the Puck header component
renderHeaderActions (Component [optional]): Render function for overriding the Puck header actions. Use a fragment.
headerTitle (string [optional]): Set the title shown in the header title
headerPath (string [optional]): Set a path to show after the header title
plugins (Plugin[] [optional]): Array of plugins that can be used to enhance Puck

`<Render>`

The <Render> component renders user-facing UI using Puck data.

config (Config): Puck component configuration
data (Data): Data to render

`Config`

The Config object describes which components Puck should render, how they should render and which inputs are available to them.

root (object)
fields (object):
title (Field): Title of the content, typically used for the page title.
[fieldName] (Field): User defined fields, used to describe the input data stored in the root key.
render (Component): Render a React component at the root of your component tree. Useful for defining context providers.
components (object): Definitions for each of the components you want to show in the visual editor
[componentName] (object)
fields (Field): The Field objects describing the input data stored against this component.
render (Component): Render function for your React component. Receives props as defined in fields.
defaultProps (object [optional]): Default props to pass to your component. Will show in fields.

`Field`

A Field represents a user input field shown in the Puck interface.

type (text | textarea | number | select | radio | external | array): The input type to render
label (text [optional]): A label for the input. Will use the key if not provided.
arrayFields (object): Object describing sub-fields for items in an array input
[fieldName] (Field): The Field objects describing the input data for each item
getItemSummary ((object, number) => string [optional]): Function to get the name of each item when using the array or external field types
defaultItemProps (object [optional]): Default props to pass to each new item added, when using a array field type
options (object[]): array of items to render for select or radio inputs
label (string)
value (string | number | boolean)
adaptor (Adaptor): Content adaptor if using the external input type
adaptorParams (object): Paramaters passed to the adaptor

`Data`

The Data object stores the puck state.

root (object):
title (string): Title of the content, typically used for the page title
[prop] (string): User defined data from root fields
content (object[]):
type (string): Component name
props (object):
[prop] (string): User defined data from component fields

`Adaptor`

An Adaptor can be used to load content from an external content repository, like Strapi.js.

name (string): The human-readable name of the adaptor
fetchList ((adaptorParams: object) => object): Fetch a list of content and return an array

NB Using an adaptor on the reserved field name _data will spread the resulting data over your object, and lock the overridden fields.

`Plugin`

Plugins that can be used to enhance Puck.

renderRoot (Component): Render the root node of the preview content
renderRootFields (Component): Render the root fields
renderFields (Component): Render the fields for the currently selected component
