Redux Middleware (thunks)

[geremora]

I'm trying to make an API call from custom component in my plugin. I'm using the flex-plugin package.

I can't to configure the middleware like thunks with redux.

The code in states/index.js:

import { combineReducers } from 'redux';
import { reduce as CustomTaskListReducer } from './CustomTaskListState';

// Register your redux store under a unique namespace
export const namespace = 'test-uva';

// Combine the reducers
export default combineReducers({
  customTaskList: CustomTaskListReducer
});

The main plugin code is:

init(flex, manager) {
    this.registerReducers(manager);
   flex.TaskInfoPanel.Content.replace(
      <ExtraInfoPanel key="extra-info-component"/>,
      {}
    ); 
  }

  /**
   * Registers the plugin reducers
   *
   * @param manager { Flex.Manager }
   */
  registerReducers(manager) {
    if (!manager.store.addReducer) {
      // eslint: disable-next-line
      console.error(
        `You need FlexUI > 1.9.0 to use built-in redux; you are currently on ${VERSION}`
      );
      return;
    }
    manager.store.addReducer(namespace, reducers);
  }

I see something about it in https://www.twilio.com/docs/flex/ui-migration-guide but I don't know how integrate it with the current code.

@geremora Did you manage to find a solution for this?

I've got the following response from support:

Adding middleware is possible from Flex-UI if you are hosting the UI yourself. You can add a wrapper that allows a plugin to add middleware or provide a custom store with the Manager's create method. i.e. Flex.Manager.create(appConfig, CustomMiddlewareStore)

Unless you are hosting the UI, it seems the best option at the moment is not using middlewares at all: https://medium.com/velotio-perspectives/how-to-make-asynchronous-calls-in-redux-without-middlewares-cbf7181020b2

If you are hosting the whole thing yourself it's not a plugin anymore.

Is this the official answer to this at the moment, as of March 2020?

Hello, we currently don't have a timeline for supporting redux within plugins. I am tagging this as a feature request and will keep this issue posted when we have more clarity.

It's June 2022 and this issue just popped up again for one of our clients. Can we now use any Redux middleware on a Flex plugin?

Hi,

This is a long open item more than a year now, hence closing it. Feel free to reopen it if still required.
