We're celebrating 5,000 stars on GitHub! Thank you to our wonderful community! :star_struck:

Puck v0.16 is a big release, introducing the headline permissions API and — you guessed it — quality of life improvements. This one took a while to put together, and we appreciate your patience and support :pray:

TLDR

• Permissions: Toggle Puck features like duplication, dragging, deletion through the new permissions and resolvePermissions APIs.
• Action bar override: Create custom action bars using the actionBar override, or extend the default one using the new <ActionBar> component.
• iframe style injection: Access the iframe document to inject styles directly, or make other changes, via the new iframe override. We also introduced the emotion-cache plugin for the common Emotion use-case.
• History injection: Inject the undo/redo history via the a series of new APIs
• React to actions: React to actions dispatched by Puck via the onAction callback.
• Optional fields: Optional props are no longer required to define in fields, since they may be defined

Highlights

:closed_lock_with_key: Permissions

Permissions enable you to toggle core Puck functionality globally, on a per-component basis or dynamically. Huge thanks to @xaviemirmon for his efforts on this.

export function Editor() {
  return (
    <Puck
      permissions={{
        delete: false,
        duplicate: true
      }}
    />
  );
}

:screwdriver: Action bar override

The new actionBar override enables you to create a custom action bar overlay, or extend the default one using the <ActionBar> component:

const overrides = {
  actionBar: ({ children }) => (
    <ActionBar label="Actions">
      {/* Render default actions */}
      <ActionBar.Group>{children}</ActionBar.Group>

      {/* Render new actions */}
      <ActionBar.Group>
        <ActionBar.Action onClick={() => console.log("Clicked!")}>
          ★
        </ActionBar.Action>
      </ActionBar.Group>
    </ActionBar>
  ),
};

:nail_care: iframe style injection

The iframe override enables you to access the iframe document, making it possible to inject styles into the head:

const overrides = {
  iframe: ({ children, document }) => {
    useEffect(() => {
      if (document) {
        document.body.setAttribute("style", "background: hotpink;");
      }
    }, [document]);

    return <>{children}</>;
  },
};

The new emotion-cache plugin uses this API to create an emotion cache inside the iframe, making Puck easy to use with any Emotion-based component library.

:scroll: History injection

Use the new history injection APIs to provide your own undo/redo history via the initialHistory prop, or dynamically via the setHistories and setHistoryIndex functions from usePuck().history.

const historyState = {
  data: {
    root: {
      props: { title: "My History" },
    },
  },
};

export function Editor() {
  return (
    <Puck
      initialHistory={{
        histories: [{ state: historyState }],
        index: 0,
      }}
      // ...
    />
  );
}

React to actions

The onAction API enables you to react to Puck’s internal actions as they’re dispatched:

export function Editor() {
  return (
    <Puck
      onAction={(action, appState, prevAppState) => {
        if (action.type === "insert") {
          console.log("New component was inserted", appState);
        }
      }}
    />
  );
}

Breaking changes

history.data is now history.state

When using the usePuck history API, data is now renamed state.

history.id is now optional (TypeScript)

When using the usePuck history API id is now optional. Puck will always generate an id, but TypeScript may complain.

lastData is now returned as null instead of {} when empty in resolvers

When using the lastData option provided to resolveData or resolveFields functions, and there is no previous data, lastData will now be null instead of {}.
