Call dispatch with more than one argument

[eugeny-dementev]

Original redux dispatch allow to pass more than one argument thats in result will be received in the middleware and all passed arguments will be logged. It's very useful and flexible. But dispatch function that passed to mapDispatchToProps handle only first argument and middleware always log array with that first argument.

// Redux 3.6.0

const middlewares = [
  function logArguments (store) {
    return next => (...args) => {
      console.log(args);

      next(...args);
    }
  }
];

const store = createStore(() => {}, applyMiddleware(...middlewares));

store.dispatch({ type: 'NOOP' }, { arg: 'second' }, { arg: 'third' });

// [ { type: 'NOOP' }, { arg: 'second' }, { arg: 'third' } ]

Actually i didn't find any documentation about this way to use dispatch so it'll be nice to also clarify that moment.

This is a question regarding Redux, not React-Redux. In particular, this was heavily discussed in reduxjs/redux#1813 . As a quick summary of that thread, it won't work because the entire ecosystem assumes that only one thing is passed to dispatch at a time. If you're looking to batch up dispatched actions (especially to minimize the number of subscriber notifications), there's a variety of possible batching addons you can use, such as https://github.com/manaflair/redux-batch .

Thank you. You were right, the issue is about ecosystem. It was previuos middleware thats handle and pass to next callback only one argument.
