throwing error when using redux-multi

[rnsloan]

#40

This commit added:

if (typeof action.type === 'undefined') {
  throw new Error(
    'Actions may not have an undefined "type" property. ' +
    'Have you misspelled a constant?'
  );
}

This will throw if you are using arrays that redux-multi will handle e.g:

[ 
  { type: 'action1',
    payload: { id: '1234' } 
  },
  { type: 'action2',
    payload: { id: '5678' } 
  } 
]

This check is from redux itself. If it will not work here - then it will not also work with redux.

But it will work and will not give an error, because when you are using redux-multi middleware - it just dispatches each single action from array separately:

function multi ({dispatch}) {
  return next => action =>
    Array.isArray(action)
      ? action.filter(Boolean).map(dispatch)
      : next(action)
}
