Returning a getters in a computed create a loop - vue.js

Question

I am calling inside the computed an action from the store to run it and after I am returning a getter, this will create a loop.
The HTML
{{loadedProjects}}
The computed
computed: {
loadedProjects() {
this.$store.dispatch("getProjects");
return this.$store.getters.loadedProjects;
}
}
The store
import Vuex from "vuex";
import axios from "axios";
const createStore = () => {
return new Vuex.Store({
state: {
loadedProjects: []
},
mutations: {
setProjects(state, projects) {
state.loadedProjects = projects
}
},
actions: {
getProjects(vuexContext) {
console.log("hello1")
return axios.get("THE API URL")
.then(res => {
console.log("hello2")
vuexContext.commit("setProjects", res.data);
})
.catch(e => console.log(e));
}
},
getters: {
loadedProjects(state) {
return state.loadedProjects;
}
}
});
};
export default createStore;
I expect to call my action to populate my state and after to return my state to render my data.

Answer 1

What is the point of using the store action that makes an API call inside the computed property ... maybe you want to trigger loadedProjects change ? ....computed property is not asynchronous so either way the return line will be executed before the you get the response... you might try vue-async-computed plugin OR just use the call on the created hook like you have done which is the better way and you don't have to use a computed property you can just {{ $store.getters.loadedProjects }} on your template

Answer 2

Computed properties should not have side effects (e.g. calling a store action, changing data, and so on). Otherwise it can happen that the triggered side effect could lead to a re-rendering of the component and possible re-fetching of the computed property. Thus, an infinite loop

I changed the code like that:
created: function () {
this.$store.dispatch("getProjects")
},
computed: {
loadedProjects() {
return this.$store.getters.loadedProjects
}
}
It is working now but I would like to know but I have that problem working inside the computed and also I wonder if it's the best solution. Any help????
