Worked on enhancing cross-platform reliability in the logseq/logseq repository by improving the Switch React Development Mode workflow. Focused on replacing shell-based file operations with Node.js’s fs.renameSync within gulpfile.js, ensuring consistent file renaming across Windows, macOS, and Linux environments. Incorporated robust error handling to surface failures early, reducing build-time issues and improving CI stability. This approach standardized file system operations, eliminated platform-specific build inconsistencies, and streamlined the onboarding process for new contributors. Utilized JavaScript and Node.js, with an emphasis on build tools and file system operations, to deliver a more predictable and maintainable development experience for the project.
