#@flowgram.ai/panel-manager-plugin

A plugin for managing different types of panels.

#Features

• Easily integrate custom panels on the right or bottom of the canvas as React components with minimal setup.

• No need for complex style adaptations—the plugin automatically calculates panel boundaries and layout.

• Automatically manages the entry and exit of the panel queue.

#Quick Start

1. Installation

npm install @flowgram.ai/panel-manager-plugin

2. Register the plugin

The registration process is basically the same as other Flowgram plugins. Just make sure you don’t create duplicates and eventually pass it into the corresponding LayoutEditorProvider.

import { createPanelManagerPlugin } from '@flowgram.ai/panel-manager-plugin';

const editorProps = useMemo(() => ({
  plugins: () => [createPanelManagerPlugin({})]
}), []);

return (
  <FreeLayoutEditorProvider {...editorProps}>
    <EditorRenderer />
  </FreeLayoutEditorProvider>
)

3. Register panel components

A panel registration requires a unique key and a render function render that returns a ReactNode.

For example, here’s a node form panel:

import { type PanelFactory } from '@flowgram.ai/panel-manager-plugin';

export const NODE_FORM_PANEL = 'node-form-panel';
export const nodeFormPanelFactory: PanelFactory<NodeFormPanelProps> = {
  key: NODE_FORM_PANEL,
  defaultSize: 400,
  render: (props: NodeFormPanelProps) => <NodeFormPanel {...props} />
}

Pass the defined object into the plugin:

createPanelManagerPlugin({
  factories: [nodeFormPanelFactory]
  getPopupContainer: (ctx) => ctx.playground.node.parentNode,
  autoResize: true
})

4. Open/close panels

Opening and closing panels is handled through an instance of PanelManager:

import { PanelManager } from '@flowgram.ai/panel-manager-plugin';

class NodeFormService {
  @inject(PanelManager): panelManager: PanelManager;

  openPanel(nodeId: string) {
    this.panelManager.open(NODE_FORM_PANEL, 'right', {
      props: {
        nodeId
      }
    })
  }
  closePanel() {
    this.panelManager.close(NODE_FORM_PANEL)
  }
}

Alternatively, you can also access the instance in a React component via a hook:

import { usePanelManager } from '@flowgram.ai/panel-manager-plugin';

const panelManager = usePanelManager();

<button
  onClick={() => panelManager.open(TEST_RUN_FORM_PANEL, 'right')}
>
  Test Run
</button>
