flash-messages

A redux reducer and a set of actions to implement flash messages in a redux
application.

Note: this library provides only the data layer. In order to display the messages in
your frontend, you must read the current messages from the corresponding
reducer.

Work In Progress Warning

The public interface of this project is being actively developed. It is,
therefore, still evolving and subject to sudden change. Wait until version
1.0.0 if you want to enjoy a stable API.

Using

Adding the reducer to your root reducer:

import { combineReducers } from 'redux';
import { flashMessagesReducer as flashMessages } from '@zooppa/flash-messages';
export default combineReducers({
  flashMessages
});

Dispatching a message:

// your component
import { receiveFlashMessage } from '@zooppa/flash-messages';
store.dispatch(receiveFlashMessage({
  type: 'success', // ['success', 'warning', 'error', ...]
  text: 'my text'
}));

Dispatching a timed message:

import { receiveTimedFlashMessage } from '@zooppa/flash-messages';
store.dispatch(receiveTimedFlashMessage({
  type: 'success',
  text: 'this message will disappear in 3000 ms'
}, {          // optional config object
  time: 3000  // default: 3000
}))
