Question

What are the benefits of utilizing Vue.set to mutate Vuex with an observable object?

Looking to achieve: What is the most effective method for updating a specific record within the Vuex state using one bulk write process?

Situation: Within the Vuex state, there exists a collection of records each initialized with default values.

Approach A component initializes and utilizes a getter to access a single record. The goal is to include new properties in the record and replace existing values.

Inquiry Is it considered appropriate to make changes to the object retrieved through the Vuex getter and subsequently commit the entire updated result to the state? Moreover, what would be the optimal strategy for this task considering that it involves overwriting an existing record in Vuex?

P.S: Additionally, I am curious about the potential impact on other components accessing the same record being overwritten. Any insights or advice on this matter would be greatly appreciated! :-)

Answer №1

Always follow the proper protocol when updating Vuex data

1) To begin, make a copy of the getter record. Make sure to perform a deep clone if the record contains anything other than basic properties, such as objects or functions. Various cloning methods are available here, but be cautious as not all provide accurate deep cloning.

2) After making changes to the duplicate, trigger a Vuex action that in turn triggers a mutation. It's best practice to only trigger mutations from actions.

3) Within that mutation, use Vue.set (or splice) to update the state record.

4) Remember, if you directly alter the getter, those changes will carry over to any other components using it.

For more information on handling change detection limitations, check out the VueJS reactivity guide.

Situations arise where you need to add multiple properties to an existing object using methods like Object.assign() or _.extend(). However, any new properties added will not automatically trigger changes. In these cases, it's better to create a new object that combines properties from both the original and mixin objects:

// Instead of `Object.assign(this.someObject, { x: 1, y: 2 })`
this.someObject = Object.assign({}, this.someObject, { x: 1, y: 2 })
