Handling Large JSON Responses Efficiently in Node.js with Streams
I've been struggling with this for a few days now and could really use some help. I'm deploying to production and I've been banging my head against this for hours. I'm currently working with a Node.js application that interacts with a REST API returning large JSON responses, sometimes exceeding 10MB. I've noticed that when I try to parse these large responses using `JSON.parse()`, I run into performance optimization and occasionally encounter memory usage spikes that lead to 'JavaScript heap out of memory' errors. I've tried using the built-in `http` module to pipe the response directly into a file first, like this: ```javascript const http = require('http'); const fs = require('fs'); http.get('http://api.example.com/large-json', (res) => { const writeStream = fs.createWriteStream('response.json'); res.pipe(writeStream); writeStream.on('finish', () => { writeStream.close(); console.log('Downloaded JSON file successfully.'); }); }); ``` This approach works, but it still requires reading the entire file back into memory to parse it later, which I believe defeats the purpose of handling large JSON data efficiently. I read about using streams for JSON parsing, which could help in processing the JSON data in chunks instead of loading it all into memory. However, I'm not sure how to implement this correctly. Could someone provide an example of how to parse a large JSON response using streams in Node.js? Also, any tips on handling potential errors would be greatly appreciated. I'm using Node.js v16.14.0. I'm working on a CLI tool that needs to handle this. How would you solve this? My team is using Javascript for this service. What's the correct way to implement this? The project is a microservice built with Javascript. Any suggestions would be helpful. I'm on Linux using the latest version of Javascript. Any suggestions would be helpful.
