Worked on the oxc-project/oxc repository to enhance the stability of Rust-based backend code by addressing a runtime panic related to non-ASCII variable name handling during transpilation. The solution involved replacing byte-based truncation with character-based truncation in the get_var_name_from_node function, ensuring correct processing of multi-byte UTF-8 identifiers such as Greek, Korean, and mixed scripts. This approach reduced runtime failures and improved reliability for diverse codebases. Targeted tests were added to validate the fix, and a performance guard was implemented to avoid unnecessary allocations. The work aligned with established Babel traversal patterns, strengthening cross-language compatibility and robustness.
Month: 2025-11 — Delivered a stability improvement for non-ASCII variable name handling in the oxc project, eliminating a panic during transpilation when encountering multi-byte identifiers. The fix focuses on robust character-based truncation for get_var_name_from_node, replacing the previous byte-based truncation that could cut in the middle of a multi-byte character. This work reduces runtime failures and makes the transpiler reliable for codebases with non-ASCII identifiers.
