How to get state from plugin's redux in controlPanel?

[nick-shaydayuk]

Hi! Can anyone suggest best practices for using the control panel in conjunction with plugins?
While developing a plugin, I encountered the problem that I can't get data from my plugin's redux in the panel.
(The plugin I want to connect uses redux to manage its state) The data is needed so that I can save user settings when the page is reloaded. For example, Preset has a plugin with an interactive table, where the required functionality is implemented.
Any help/suggestions or links would be appreciated!

Hey @nick-shaydayuk! I'm here to help you with any bugs, questions, or contributions you have. If you need assistance, feel free to ask!

To access the Redux state from a plugin in the control panel, you can use the useSelector hook from react-redux. This hook allows you to select and retrieve the necessary state from the Redux store. Here's a basic example of how you can use it:

import { useSelector } from 'react-redux';

const MyComponent = () => {
  const myPluginState = useSelector((state) => state.myPlugin);

  // Use myPluginState as needed
  return <div>{JSON.stringify(myPluginState)}</div>;
};

In this example, replace myPlugin with the specific slice of the state that your plugin manages. This approach ensures that your component will re-render whenever the selected state changes, keeping your UI in sync with the Redux store.

Additionally, if you need to map state to props in a more traditional way, you can use the connect function from react-redux:

import { connect } from 'react-redux';

const mapStateToProps = (state) => ({
  myPluginState: state.myPlugin,
});

const MyComponent = ({ myPluginState }) => {
  // Use myPluginState as needed
  return <div>{JSON.stringify(myPluginState)}</div>;
};

export default connect(mapStateToProps)(MyComponent);

This method is useful if you prefer to keep your component as a class component or if you want to separate the logic of mapping state to props from the component itself.

For saving user settings and ensuring they persist across page reloads, consider using middleware like redux-persist to automatically save and rehydrate the Redux state. This can help maintain user settings without additional manual handling.

Well, i assume i have to give more details:
I try to implement kepler plugin in my application, but as it says here, i have to mount the Kepler.gl reducer, so it complicates using state in controlPanel

To integrate the Kepler.gl plugin and access its state in your control panel, you'll need to mount the Kepler.gl reducer into your existing Redux store. Here's a general approach to achieve this:

1. Mount the Kepler.gl Reducer: Add the Kepler.gl reducer to your Redux store. You can do this by combining it with your existing reducers.

   import { combineReducers } from 'redux';
   import keplerGlReducer from 'kepler.gl/reducers';
   
   const rootReducer = combineReducers({
     // Your other reducers
     keplerGl: keplerGlReducer,
   });
   
   export default rootReducer;

2. Access Kepler.gl State in the Control Panel: Use the useSelector hook from react-redux to access the Kepler.gl state in your control panel components.

   import { useSelector } from 'react-redux';
   
   const ControlPanel = () => {
     const keplerState = useSelector((state) => state.keplerGl);
   
     // Use keplerState as needed
     return <div>{JSON.stringify(keplerState)}</div>;
   };

3. Persist State if Needed: If you need to persist the Kepler.gl state across page reloads, consider using middleware like redux-persist or redux-localstorage to save and rehydrate the state.

By following these steps, you should be able to integrate the Kepler.gl plugin and access its state within your control panel.
