This repo is a fork of ts-case-convert, which no longer seems to be maintained. All credit for the work should go to its author @RossWilliams.
typescript-case-convert converts object keys between camelCase, snake_case, and PascalCase while preserving Typescript type information, code completion, and type validation. See tests for detailed conversion tests.
