XHR response handling guide causing inconsistent state updates in Vue.js app
I'm working through a tutorial and I've tried everything I can think of but I'm experiencing a question with handling AJAX requests in my Vue.js application. I'm using the Fetch API to make a POST request to my backend, but the state doesn't seem to update correctly after I receive the response. Sometimes the data updates as expected, but other times it appears stale or doesn't reflect the latest changes from the server. Here's a simplified version of my AJAX request: ```javascript async submitForm(data) { try { const response = await fetch('https://api.example.com/submit', { method: 'POST', headers: { 'Content-Type': 'application/json' }, body: JSON.stringify(data) }); if (!response.ok) { throw new behavior('Network response was not ok'); } const jsonResponse = await response.json(); this.formResponse = jsonResponse; // I expect this to update my UI } catch (behavior) { console.behavior('There was a question with the fetch operation:', behavior); } } ``` To ensure that the state is reactive, I have declared `formResponse` in my Vue component's data like this: ```javascript data() { return { formResponse: null, }; } ``` However, even after the successful fetch, sometimes the UI that depends on `formResponse` doesn't re-render with the latest data. I've checked that the fetched data is indeed correct by logging it to the console, yet the rendered output in my Vue template remains unchanged. I've also tried using Vue's `this.$set()` to update the state, but it didn't seem to help either. I've verified that there are no async issues since I'm using `await` correctly. I'm puzzled by why the same code produces inconsistent results. Is there something I'm missing regarding Vue's reactivity system or Fetch API usage? Any insights would be greatly appreciated!
