Root Configuration

The root is the top-level component within Puck. It:

Renders a single wrapper around your other components. This can be overwritten with a render function.
Stores meta data, like the page title. This can be extended with fields.

Configuring the root is similar to configuring components.

The root `render` function

Use the root parameter to specify a render function:

const config = {
  components: {
    HeadingBlock: {
      render: () => {
        return <h1>Hello, world</h1>;
      },
    },
  },
  root: {
    render: ({ children }) => {
      return <div>{children}</div>;
    },
  },
};

The root render function will wrap all of the components. children is a node containing the nested components.

If you don’t render children, your components will not be rendered (unless you’re defining custom root DropZones).

Example output

Given a minimal data payload containing one HeadingBlock

{
  "content": [
    {
      "type": "HeadingBlock",
      "props": {
        "id": "HeadingBlock-1234"
      }
    }
  ],
  "root": {}
}

the example config will render HTML nodes like this:

<!-- root render -->
<div>
  <!-- HeadingBlock render -->
  <h1>Hello, world</h1>
 
  <!-- Remining nodes -->
</div>

Adding fields

Root fields provide user input to the root render method, and can be used to store metadata.

By default, root is configured with a title text field:

const config = {
  // ...
  root: {
    render: ({ children, title }) => {
      return (
        <div>
          <h1>{title}</h1>
          {children}
        </div>
      );
    },
  },
};

We can override the default field configuration by providing custom Fields to the fields parameter:

const config = {
  // ...
  root: {
    fields: {
      title: { type: "text" }, // We need to redefine the `title` field if we want to retain it
      description: { type: "textarea" },
    },
    render: ({ children, title, description }) => {
      return (
        <div>
          <h1>{title}</h1>
          <p>{description}</p>
          {children}
        </div>
      );
    },
  },
};

When the user modifies the inputs, the editor will produce a data payload like this:

{
  "content": [
    // ...
  ],
  "root": {
    "props": {
      "title": "Hello, world",
      "description": "Lorem ipsum"
    }
  }
}

TypeScript

Generic types can be passed to the Config type to strictly type your root configuration:

import type { Config } from "@measured/puck";
 
type RootProps = {
  description: string;
};
 
const config: Config<{}, RootProps> = {
  // ...
};

Setting default props

Provide an object to the defaultProps parameter to configure default props for the root fields:

const config = {
  // ...
  root: {
    fields: {
      title: { type: "text" },
      description: { type: "textarea" },
    },
    defaultProps: {
      title: "Hello, world",
      description: "Lorem ipsum",
    },
    render: ({ children, title, description }) => {
      return (
        <div>
          <h1>{title}</h1>
          <p>{description}</p>
          {children}
        </div>
      );
    },
  },
};

Unlike default parameters, defaultProps are stored in the data payload and will populate the Puck fields.
