Required params

`render(props)`

A render function to render your component. Receives props as defined in fields, and some internal Puck props.

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

Args

Arg	Example	Type
`props`	`{ id: "id", puck: { renderDropZone: DropZone } }`	Object

`props.id`

A unique ID generated by Puck for this component. You can optionally apply this, or use your own ID.

`props.puck.renderDropZone`

A render method that creates a <DropZone> for creating nested components. Use this method instead of the <DropZone> when implementing React server components.

const config = {
  components: {
    Example: {
      render: ({ puck: { renderDropZone } }) => {
        return <div>{renderDropZone({ zone: "my-content" })}</div>;
      },
    },
  },
};

`...props`

The remaining props are provided by the user-defined fields.

Returns

Returns a ReactNode

Optional params

`fields`

An object describing which Field to show for each prop passed to the component.

const config = {
  components: {
    HeadingBlock: {
      fields: {
        title: {
          type: "text",
        },
      },
      render: ({ title }) => <h1>{title}</h1>,
    },
  },
};

Interactive Demo

Example

Hello, world

`defaultProps`

Default props to apply to a new instance of the component.

const config = {
  components: {
    HeadingBlock: {
      fields: {
        title: {
          type: "text",
        },
      },
      defaultProps: { title: "Hello, world" },
      render: ({ title }) => <h1>{title}</h1>,
    },
  },
};

Interactive Demo

Example

Hello, world

`label`

A label to show when referring to your component within the Puck editor. Defaults to the key of your component.

const config = {
  components: {
    HeadingBlock: {
      label: "Heading Block",
      render: () => <h1>Hello, World</h1>,
    },
  },
};

Interactive Demo

Heading Block

`resolveData(data, params)`

Dynamically change the props and set fields as read-only. Can be used to make asynchronous calls.

This function is triggered when <Puck> renders, when a field is changed, or when the resolveAllData function is called.

Example mapping 'title' to 'resolvedTitle'

const config = {
  components: {
    HeadingBlock: {
      fields: {
        title: {
          type: "text",
        },
      },
      resolveData: async ({ props }) => {
        return {
          props: { resolvedTitle: props.title },
          readOnly: { resolvedTitle: true },
        };
      },
      render: ({ resolvedTitle }) => <h1>{resolvedTitle}</h1>,
    },
  },
};

Interactive Demo

Try changing the "title" field

Args

Prop	Example	Type
`data`	`{ props: { title: "Hello, world" }, readOnly: {} }`	Object
`params`	`{ changed: { title: true } }`	Object

`data.props`

The current props for the component.

const resolveData = async ({ props }) => {
  return {
    props: { resolvedTitle: props.title },
  };
};

`data.readOnly`

The fields currently set to read-only for this component.

`params.changed`

An object describing which props have changed on this component since the last time resolveData was called.

Example only updating 'resolvedTitle' when 'title' changes

const resolveData = async ({ props }, { changed }) => {
  if (!changed.title) {
    return { props };
  }
 
  return {
    props: { resolvedTitle: props.title },
  };
};

`params.lastData`

The data object from the previous run of this function.

Returns

Prop	Example	Type
`data`	`{ props: { title: "Hello, world" }, readOnly: {} }`	Object

`data.props`

A partial props object containing modified props. Will be spread into the other props.

Example only updating resolvedTitle when title changes

const resolveData = async ({ props }) => {
  return {
    props: { resolvedTitle: props.title },
  };
};

`data.readOnly`

A partial object describing fields to set as readonly. Will be spread into the existing readOnly state.

Example only updating resolvedTitle when title changes

const resolveData = async ({ props }) => {
  return {
    props: { resolvedTitle: props.title },
    readOnly: { resolvedTitle: true }, // Make the `resolvedTitle` field read-only
  };
};

`resolveFields(data, params)`

Dynamically set the fields for this component. Can be used to make asynchronous calls.

This function is triggered when the component data changes.

Example changing one field based on another

const config = {
  components: {
    MyComponent: {
      resolveFields: (data) => ({
        fieldType: {
          type: "radio",
          options: [
            { label: "Text", value: "text" },
            { label: "Textarea", value: "textarea" },
          ],
        },
        title: {
          type: data.props.fieldType,
        },
      }),
      render: ({ title }) => <h1>{title}</h1>,
    },
  },
};

  }
 
  return {
    title: {
      type: fieldType,
    },
