Optimizing JSON Parsing Performance in a Next.js Application
I'm converting an old project and Currently developing a Next.js application where we rely heavily on external APIs that return large JSON payloads... The performance of our application has become a concern, especially during the initial data fetching phase. I've already switched from the built-in fetch to Axios, aiming for better performance, but I'm still not satisfied with the parsing speed. I've been experimenting with different methods to optimize JSON parsing. For instance, I started by using the native `JSON.parse()` to handle the response but found that it became a bottleneck with larger datasets. Here’s a snippet of the code I’ve been using: ```javascript const fetchData = async () => { try { const response = await axios.get('https://api.example.com/data'); const data = JSON.parse(response.data); setData(data); } catch (error) { console.error('Error fetching data', error); } }; ``` After profiling, I noticed that the parsing time was quite significant, especially when the payload exceeds 1MB. To address this, I decided to explore chunking the data on the server-side, but that added complexity to the API without guaranteed results. I also tried libraries like `superjson`, which promises better serialization performance, but the integration with our current state management is proving a bit tricky. In my recent attempts, I’ve also looked into using streams for handling the JSON data as it arrives, but I’m unsure how to implement it effectively in the context of React state updates. Here’s a rough idea of what I’m considering: ```javascript const streamData = async () => { const response = await fetch('https://api.example.com/stream'); const reader = response.body.getReader(); while (true) { const { done, value } = await reader.read(); if (done) break; const chunk = new TextDecoder('utf-8').decode(value); // Process the chunk } }; ``` I wonder if anyone has tackled similar issues or could provide insights on optimizing JSON parsing specifically for Next.js applications. Any best practices or alternative libraries you’ve found useful in speeding up this process? I'm coming from a different tech stack and learning Javascript. This is part of a larger REST API I'm building.
