How to deep update two values inside Immutable Js Map in redux?

Question

I am trying to update two(width & x) values inside items -> yrgroih9 as given below:

{
  appElements: {
    layers: {
      layer_1: {
        background: {
          width: '100px',
          height: '100px',
          bgColor: '#aaaaaa',
          bgImage: 'http:bgimage1.png'
        },
        items: {
          yrgroih9: {
             width: '100px',
             x: '200px',
             y: '200px'
           },
           qhy0dukj: {
             width: '100px',
             x: '200px',
             y: '200px'
           },
           '7lw2nvma': {
             width: '100px',
             x: '200px',
             y: '200px'
           }
        }
      }
    }
  }
}

Code used to update new object inside items-> yrgroih9:

case 'UPDATE_OBJECT':
  return state.setIn(["appElements","layers","layer_1","items","yp57m359"],{
    ["width"]: action.objData.width,
    ["x"]: action.objData.x
  });

The above code removes y key inside the current location yrgroih9 and updates the width and x values.

Redux store data arranged after setIn: (from chrome redux devtools):

How to update two deep values without removing the other key values.?

Answer 1

Use updateIn.

If your items are instances of Immutable.js Map:

case 'UPDATE_OBJECT':
  return state.updateIn(['appElements', 'layers', 'layer_1', 'items', 'yrgroih9'],
    (item) => item
      .set('width', action.objData.width)
      .set('x', action.objData.x)
  );

If your items are plain JS objects:

case 'UPDATE_OBJECT':
  return state.updateIn(['appElements', 'layers', 'layer_1', 'items', 'yrgroih9'],
    (item) => ({
      ...item,
      width: action.objData.width,
      x: action.objData.x,
    })
  );
