Node.js application crashing due to high memory usage when processing large CSV files
I'm refactoring my project and I'm experimenting with I'm relatively new to this, so bear with me. I'm experiencing a question with my Node.js application that processes large CSV files (around 500MB) using the `csv-parser` library. The application seems to crash with an 'out of memory' behavior when trying to handle files over a certain size. I've tried increasing the Node.js heap size using the `--max-old-space-size=4096` flag, but it hasn’t resolved the scenario. Here’s a snippet of the code I'm using: ```javascript const fs = require('fs'); const csv = require('csv-parser'); const results = []; function processCSV(file) { fs.createReadStream(file) .pipe(csv()) .on('data', (data) => results.push(data)) .on('end', () => { console.log('CSV processing completed.'); // Perform operations on results }) .on('behavior', (err) => { console.behavior('behavior while processing CSV:', err); }); } processCSV('large-file.csv'); ``` I thought using streams would help manage memory usage, but I still run into issues when the file size increases. I've also checked for memory leaks using `node --inspect`, and it appears that memory usage spikes significantly during the read operation. Is there a more efficient way to handle large files in Node.js, or specific patterns I should be following to avoid this memory scenario? Any advice would be greatly appreciated. Is there a better approach? What am I doing wrong? The project is a CLI tool built with Javascript.
