Mitesh Patel enhanced the SalesforceCommerceCloud/pwa-kit repository by refactoring its garbage collection process and introducing a dedicated memory testing endpoint. He reworked the Node.js server-side logic so that garbage collection is no longer triggered on every invocation, instead allowing developers to control it via the FORCE_GC environment variable. This adjustment, implemented in JavaScript, aligned with the project’s existing memory management strategy and reduced the risk of regressions by cherry-picking targeted changes. The new memory testing endpoint improved observability and debugging workflows, enabling more efficient diagnosis of memory-related issues during development and staging, and strengthening the project’s DevOps practices.
