How I Stopped Node.js from Freezing While Bulk-Processing 1,500+ Excel Rows

1. 1Read Excel files using a streaming library like 'xlsx-stream' to avoid loading entire files into memory
2. 2Use a queueing system like 'bull-queue' to process rows in batches, reducing memory usage
3. 3Implement a worker thread pool using 'worker_threads' to parallelize processing and improve performance
4. 4Configure the worker threads to handle errors and restart if necessary
5. 5Test the system with a large dataset to ensure it can handle the load without freezing

Software engineers and DevOps teams benefit from this knowledge to ensure smooth data processing and prevent system crashes, especially when working with large datasets

💡 Using streaming libraries and queueing systems can significantly improve the performance and reliability of Node.js applications when processing large datasets
