Using the Vue.js Spread Operator in place of Vue.set or Vue.delete

I'm exploring ways to utilize the spread operator for adding or removing object properties in a manner that preserves reactivity.

Within a Vuex mutation, this code snippet is successful:

Vue.set(state.sportTypes.sports, sportName, sportProperties)

However, I am interested in using the spread operator to achieve the same result and return a new object. How can I accomplish this?

state.sportTypes.sports = {...state.sportTypes.sports, {sportName: sportProperties}}

Answer №1

To effectively incorporate the specified sport properties, it is advised to eliminate the brackets surrounding {sportName: sportProperties}

Consider utilizing the following method:

state.sportTypes.sports = { ...state.sportTypes.sports, sportName: 'football' }

For better practice, it is recommended to predefine all potential fields instead of dynamically adding new attributes. By doing so, you can avoid the necessity of using Vue.set or the spread operator.
