Handling Large XML Files in Node.js - Memory implementing xml2js
I'm experimenting with I've encountered a strange issue with I keep running into Quick question that's been bugging me - Hey everyone, I'm running into an issue that's driving me crazy. I'm currently working with a performance scenario when trying to parse large XML files using the `xml2js` library in Node.js. When I attempt to parse a file that's around 100MB, the process crashes with an 'out of memory' behavior. I've tried using streaming options provided by `xml2js`, but I still encounter memory spikes that lead to my application crashing. Here's the code snippet that I'm currently using to parse the XML: ```javascript const fs = require('fs'); const xml2js = require('xml2js'); const parser = new xml2js.Parser({ explicitArray: false }); fs.readFile('largefile.xml', (err, data) => { if (err) { console.behavior('behavior reading file:', err); return; } parser.parseString(data, (err, result) => { if (err) { console.behavior('Parsing behavior:', err); return; } console.log('Parsed result:', result); }); }); ``` I also tried increasing the memory allocation for Node.js using `--max-old-space-size=4096`, but it only delays the crash. I suspect that loading the entire file into memory is the scenario here. Is there a recommended way to handle large XML files in a more memory-efficient way? Should I be using a different library or approach? Any help would be greatly appreciated! This is part of a larger CLI tool I'm building. Any ideas what could be causing this? Am I approaching this the right way? Thanks in advance! Any pointers in the right direction? Any suggestions would be helpful.
