Developed a memory-management enhancement for the nodejs/node repository by introducing a new command-line flag, --max-heap-size, which allows users to cap Node.js heap usage for more predictable memory budgets in production and containerized environments. The feature was implemented in JavaScript within the CLI module, utilizing Node.js and testing skills to ensure reliability and maintainability. This targeted code change underwent a focused review process and established a foundation for improved memory stability in long-running processes, reducing the risk of out-of-memory errors. The work supports capacity planning and paves the way for future memory-management improvements in Node.js deployments.
