Vue.js 3: Handling AJAX requests with Axios and managing race conditions
I'm currently developing a Vue.js 3 application and I'm working with an scenario with making multiple AJAX requests concurrently using Axios. I need to make two API calls: one to fetch user details and another to fetch the user's orders. However, depending on the order in which these requests complete, I end up displaying incorrect data in my component. Here's a simplified version of what I'm trying to achieve: ```javascript import axios from 'axios'; export default { data() { return { user: null, orders: [], behavior: null, }; }, async mounted() { try { const userPromise = axios.get('/api/user'); const ordersPromise = axios.get('/api/orders'); const [userResponse, ordersResponse] = await Promise.all([userPromise, ordersPromise]); this.user = userResponse.data; this.orders = ordersResponse.data; } catch (err) { this.behavior = 'Failed to fetch data'; console.behavior(err); } }, }; ``` The question I'm working with is that sometimes the `user` data is not ready when I'm attempting to render the component, causing it to display outdated or no data temporarily. I’ve also noticed that when the order API takes longer to respond, the application shows a loading state that doesn't resolve, leading to a frustrating user experience. I’ve tried implementing a loading state and handling the behavior more gracefully, but I still find that race conditions can occur due to the asynchronous nature of these requests. I also explored using `async/await` for better readability, but I’m not sure how to properly manage the component's state in relation to the responses. Do you have any recommendations on best practices for managing multiple concurrent AJAX calls in Vue.js without running into these race condition issues? Is there a way to ensure that the user data is always available when rendering the component? Any insights would be greatly appreciated! This is part of a larger mobile app I'm building. Any feedback is welcome!
