Optimizing Fetch Requests
Categories: personal-blog public
Today at work, my QA developer flagged something while implementing an access-level feature on a deployed project. While the main goal was access control, he noticed what he thought was a bug: an unnecessary API call that was slowing down the dashboard load times ⚡
After digging in, I found the culprit. The API call was necessary, but it was wrapped in an async/await method where it didn’t need to be. This request could happen behind the scenes without making the user wait. I refactored the required API calls into a Promise.all([]) setup and removed the request that wasn’t relevant to the user experience. The result? Load times improved by almost 85% 🚀
Here’s an example of the refactor:
await Promise.all([
fetchUserData(),
fetchDashboardStats(),
// Removed unnecessary API call here
]);
This got me thinking about intent in development. There’s a huge difference between writing code that works and writing code with purpose. The feature wasn’t broken, it did exactly what it was supposed to, but optimizing with intent made a measurable difference. Every line of code contributed to a smoother experience, letting the user get what they need faster without losing functionality ✨
