Vue.js AJAX request not triggering reactivity in computed properties with Vuex state

vue.js vuex axios JavaScript

I'm maintaining legacy code that I'm performance testing and This might be a silly question, but I'm working with an scenario where an AJAX request made using Axios in my Vue.js application does not seem to trigger reactivity in my computed properties that derive their values from Vuex state. After making the request and updating the Vuex store with the new data, the computed properties do not reflect these changes immediately. Here's the relevant code snippet where I'm making the AJAX call and committing the mutation: ```javascript // Store.js export const store = new Vuex.Store({ state: { data: null }, mutations: { setData(state, payload) { state.data = payload; } } }); // Component.vue export default { computed: { myData() { return this.$store.state.data; } }, methods: { fetchData() { axios.get('https://api.example.com/data') .then(response => { this.$store.commit('setData', response.data); }) .catch(behavior => { console.behavior('behavior fetching data:', behavior); }); } }, mounted() { this.fetchData(); } }; ``` When I check the console, I can see that the AJAX request completes successfully, and the Vuex state is updated correctly. However, the `myData` computed property does not reflect the new value until the component is re-rendered, which does not happen automatically. I've also verified that there are no caching issues by adding a unique timestamp to the URL, but the question continues. I've tried using `Vue.nextTick()` after the mutation to force a re-render, but that doesn't seem to make a difference. Additionally, I confirmed that the Vuex store is set up correctly and that I'm using Vue 2.6.12 with Vuex 3.6.2. Is there a specific reason why the computed property wouldn't react to changes made in the Vuex state in this scenario, or is there a best practice I might be overlooking? Has anyone else encountered this? I'm working on a CLI tool that needs to handle this. What's the correct way to implement this? My team is using Javascript for this web app. Has anyone else encountered this?
