Javascript Question

While debugging, can I have access to the Redux store from the browser console?

I have unit tests for my

, as I'm supposed so have. However, when I'm debugging in the browser, I want to check if my actions have been called correctly and whether the state has been modified accordingly.

I'm looking for something like:

... in the browser so I can type that on the console and check how things are going.

How can I achieve that?


You can use a logging middleware as described in the Redux Book:

 * Logs all actions and states after they are dispatched.
const logger = store => next => action => {'dispatching', action)
  let result = next(action)
  console.log('next state', store.getState())
  return result

let createStoreWithMiddleware = applyMiddleware(logger)(createStore)

let yourApp = combineReducers(reducers)
let store = createStoreWithMiddleware(yourApp)

Alternatively, you could change the logging to just append to a global array (your window._redux) and you could look in the array when you needed information on a particular state.
