Global action

[vanhtuan0409]

Is it possible to have an event that can be listened by multiple models 😄
For example, I have a listener that fire action every time screen media query changed. This action needs to be listened by multiple ui state models

Yes of course, just connect mediaQuery model's state for your ui state.

For your example, here is a possible solution:

import mirror, { actions } from 'mirrorx'

mirror.model({
  name: 'mediaQuery',
  initialState: {
    width: 0,
    height: 0
  },
  reducers: {
    change(state, data) {
      return { ...state, ...data }
    }
  }
})

// in your media query change event
actions.mediaQuery.change({ width, height })

// components that need to update when media query change
import Comp from './components/Comp'

const MyComponent = connect(state => {
  return {
    mediaQuery: state.mediaQuery,
    stateOfComp: state.stateOfComp
  } 
})(Comp)

Your suggestion is what I doing right now
But can 1 model reducers listen to action of another model
Like can stateOfComp model listen to action from mediaQuery model

You can. Try the mirror.hook API, though you should be careful to update state in hooks.
