My store setup is as follows:
export const store = new Vuex.Store({
state: {
someProp: someAsyncFn().then(res => res),
...
},
...
})
I'm concerned that someProp might not be waiting for the values to be resolved. Is this a problem? Should I consider setting an empty object as the default and updating the state with a mutation upon load instead?
It's important to structure your code like so:
export const store = new Vuex.Store({
state: {
someProp: null
...
},
mutations:{
initializeSomeProp: (state, payload) => {
state.someProp = payload;
}
},
actions:{
asyncSomeProp: ({commit}) => {
someAsyncFn().then(res => commit('initializeSomeProp', res))
}
}
})
When dealing with asynchronous operations, utilize actions. Implement the asyncSomeProp action to commit the initializeSomeOrop mutation by passing the result obtained from the asynchronous callback as a payload parameter.
To initialize your someProp in a component, dispatch the asyncSomeProp action within the created lifecycle hook of that component:
created(){
this.$store.dispatch('asyncSomeProp');
}
