Frequently Asked Questions

FAQs about TypeScript Formatter

Does this use the TypeScript compiler?

No. The formatter uses regex-based processing and does not require the TypeScript compiler or any npm packages. For production use, consider Prettier or the TypeScript language service.

Does it handle interfaces and types?

Yes. interface and type declarations are detected and formatted with proper newlines and indentation for their members.

Are generics supported?

Yes. Generic syntax like Array<T>, Promise<ApiResponse<User>>, and similar patterns are preserved correctly during formatting.

Will it validate the TypeScript?

No. The formatter only adjusts whitespace and line breaks — it does not type-check or validate your TypeScript syntax.

Is my code safe?

All processing runs entirely in your browser. No code is ever sent to a server.
