Worked on the brave-core-crx-packager repository to enhance cross-platform reliability in CRX packaging by addressing module path resolution and path handling challenges. Leveraged JavaScript and Node.js to resolve a Windows-specific ERR_INVALID_MODULE_SPECIFIER, implementing URL-based module path resolution and reverting unnecessary URL usage in adBlockRustUtils.js for simpler, more stable code. Standardized path handling across Windows and POSIX environments by adopting path/posix for POSIX-style paths, reducing platform-specific edge cases and improving maintainability. These updates resulted in fewer runtime errors, clearer code paths, and more robust packaging workflows, demonstrating a strong focus on cross-platform development and module resolution best practices.
