ast-grep-patterns

To perform a safe structural refactor in TypeScript, use ast-grep patterns to match and modify code structure. This approach preserves code context across files and imports during renames, extracts, or find-and-replace operations.

Run a dry-run scan before applying a TSX codemod by executing ast-grep patterns without writing changes. This allows you to preview structural replacements and verify pattern accuracy before modifying your TypeScript/TSX codebase.

Yes, you can use ast-grep to rename symbols across multiple TSX files. It applies pattern-based templates for consistent updates, ensuring your structural replace operations preserve code context across calls, imports, and JSX syntax.

The best way to find and replace code context in TypeScript without breaking imports is using ast-grep structural patterns. This method identifies and applies guarded refactors that maintain import integrity across your entire codebase.

Yes, you need ast-grep or an equivalent structural search tool installed to use these patterns. The Skill provides pattern-based templates and guarded refactors, but requires the underlying tool to execute scans and apply modifications.

You should avoid structural find-and-replace for TypeScript refactoring when simple text-based replacement is sufficient. If your changes do not require preserving code context across imports, calls, or JSX, a structural codemod may add unnecessary complexity.
