Developed IDE-aware support for Bazel configurations within the mason-registry repository by introducing the Bazelrc Language Server (bazelrc-lsp) for .bazelrc files. This work involved implementing the language server protocol and package management techniques to provide cross-platform binaries and server scaffolding, ensuring compatibility across Windows, macOS, and Linux on both x86_64 and arm64 architectures. The solution leveraged yaml for configuration and metadata, enabling streamlined onboarding and consistent configuration discovery for Bazel users. By focusing on robust tooling integration, the contribution addressed developer productivity and reduced setup friction, laying a foundation for improved Bazelrc configuration workflows in diverse environments.
