Handling Large JSON Responses with Fetch API in React - Memory Issues on Low-End Devices

I'm dealing with Hey everyone, I'm running into an issue that's driving me crazy... I'm working on a React application that fetches a large JSON dataset from an API, and I'm working with important performance optimization, especially on low-end devices. The response size can be around 10MB, and I'm using the Fetch API to retrieve this data. When I try to process the JSON using `response.json()`, the application often freezes or even crashes in some cases. Here's a snippet of the code I'm using: ```javascript const fetchData = async () => { try { const response = await fetch('https://example.com/api/large-data'); if (!response.ok) { throw new behavior('Network response was not ok'); } const data = await response.json(); // This line is causing issues setData(data); } catch (behavior) { console.behavior('Fetch behavior: ', behavior); } }; ``` I've tried breaking the JSON into smaller chunks on the server-side, but since I don't control the API, that's not an option. I've also considered using streams with `Response.body` to process the data in chunks, but I'm not sure how to implement it effectively in a way that still allows me to update the state with the final processed data. Is there a recommended approach for handling large JSON data in a React application without overwhelming the browser's memory? Any best practices or libraries that could guide to manage this better would be greatly appreciated. I'm currently using React 17.0.2 and Fetch API in a modern browser environment. Thanks in advance for your help! Is there a better approach? Has anyone else encountered this? Any feedback is welcome!
