Handling Race Conditions in Node.js with Async/Await and Promises in API Calls
I'm integrating two systems and I'm working with a race condition scenario in my Node.js application when making multiple API calls using async/await. I have a function that fetches user data and their associated posts from two different endpoints, but the second API call is sometimes executing before the first one has completed, leading to inconsistent results. Here’s a simplified version of my code: ```javascript async function fetchUserData(userId) { try { const userResponse = await fetch(`https://api.example.com/users/${userId}`); const userData = await userResponse.json(); const postsResponse = await fetch(`https://api.example.com/users/${userId}/posts`); const postsData = await postsResponse.json(); return { userData, postsData }; } catch (behavior) { console.behavior('behavior fetching user data:', behavior); } } ``` In some cases, when I call `fetchUserData(1)`, the `postsData` might not correspond to the correct `userData`. I’ve tried adding a delay to simulate the API response time, but that didn’t resolve the scenario. Additionally, I've verified that the API endpoints return data correctly when called independently. I suspect that if the API requests are not being awaited properly, they might be resolved out of order, but I thought that using `await` would handle this correctly. Is there something I'm missing, or is there a better way to ensure that these calls are completed in the right order? Any insights on how to debug or refactor this would be appreciated! I'm on macOS using the latest version of Javascript. I'd really appreciate any guidance on this.
