Frequently Asked Questions
Is my TypeScript code private?
Yes, all formatting happens entirely in your browser. Your TypeScript code is never uploaded to any server or shared with anyone. The formatter runs 100% client-side, so your source code, type definitions, and business logic remain completely private.
Does it support all TypeScript features?
Yes, the formatter supports all TypeScript syntax including interfaces, type aliases, enums, generics, decorators, utility types, conditional types, and mapped types. It uses Prettier's TypeScript parser for comprehensive and accurate formatting.
Can I format .tsx files?
The TypeScript formatter handles standard TypeScript syntax including type annotations, interfaces, and generics. For TSX files containing JSX syntax, the formatter will process the TypeScript portions. Paste your code and it will be formatted automatically.
