large-file-splitter

To split a large file into a modular folder structure, this tool identifies natural boundaries within the code, moving sections into focused modules under a dedicated folder named after the original file, with an index entrypoint preserving the public API surface.

You should refactor source code into separate modules when a single file exceeds 500 lines or grows past that threshold in the current session, creating monolithic code that requires focused maintenance and easier incremental testing.

Yes, file modularization preserves existing imports and exports by updating relative paths and maintaining API compatibility, ensuring that references remain intact while avoiding circular dependencies throughout the refactoring process.

The best way to refactor oversized files without breaking dependencies is using an automated folder-first layout that updates imports and exports, preserves the public API surface, and specifically avoids circular dependencies across the newly created modules.

Yes, you can automatically split newly created large files during a session, as the tool applies to any file type that exceeds the 500-line threshold in the current session, triggering optional automatic modularization.
