I want to pass an argument into a custom Redux middleware.
But I don't know how to use the argument inside the custom middleware.

Example:

import createStore, applyMiddleware from 'redux';
import reducers from './reducers';

const customMiddleWare = store => next => action => 
 // how to use argument here?
;

const middlewares = [customMiddleWare(argument)];

const store = createStore(
 reducers,
 applyMiddleware(...middlewares)
);

  What specifically are you trying to accomplish? You're already passing an argument into customMiddleWare but it's not the one you think you are. Not sure what your actual use-case is, but in general, that's not how middleware is structured.

As middlewares are functions you can make a wrapper function that will take your argument and return your middleware function which will have access to the provided argument.

Example:

const middlewareWrapper = customArgument => store => next => action =>
 console.log(customArgument);
}

const middlewares = [middlewareWrapper(argument)];

const store = createStore(
 reducers,
 applyMiddleware(...middlewares)
);
