How to update object properties in vuex?

Question

Vue.js

Good afternoon!
How to correctly update an object (or its individual properties) in store vuex?
Let's say there is an object in store

state:{
  params: {
    prop1: {},
    prop2: {},
    prop3: {}
  }
}

case1: get the params object and replace it completely (possibly with a change in its structure).
case2: get a params object and replace one property prop1.

Answer 1

mutations:
case1:

setParams (state, params) {
    state.params = params
}

case2:

setParamsProperty (state, obj) {
    state.params = {...state.params, ...obj }
}

where objis an object of the form:

{
  prop1: value1
}

or like this for example:

{
  prop1: value1,
  prop2: value2
}
