About TypeScript Formatter
The TypeScript Formatter formats `.ts` and `.tsx` snippets with readable indentation, including interfaces, generics, union types, async functions, and JSX blocks when present. It helps teams standardize style before TypeScript strict checks, documentation, or code review.
How to Use TypeScript Formatter
Paste TypeScript source from a component, service, config file, or documentation snippet into the editor. Format to expand interfaces, type aliases, generics, functions, imports, and React components clearly. Review long union types, object literals, and chained calls for readability. Copy output into your project, pull request, StackBlitz sandbox, or technical article.
When to Use TypeScript Formatter
Application code: Clean snippets from stack traces or gist shares. Libraries: Format public API examples in documentation. Migration: Read JavaScript-to-TypeScript conversions side by side. Education: Teach typing rules with legible samples. Code review: Normalize pasted `.ts` examples before leaving implementation notes.
Why Use This TypeScript Formatter?
TypeScript’s syntax is dense; formatting clarifies generic constraints, discriminated unions, mapped types, and JSX props. Browser-based formatting is handy when you cannot open a full IDE on a shared machine or need to clean a snippet before sending it to a teammate.
How to use
1. Paste TypeScript source from a component, service, config file, or documentation snippet into the editor.
2. Format to expand interfaces, type aliases, generics, functions, imports, and React components clearly.
3. Review long union types, object literals, and chained calls for readability.
4. Copy output into your project, pull request, StackBlitz sandbox, or technical article.
Frequently asked questions
Can I format TSX React components?
Yes. Paste `.tsx` snippets that contain typed props, JSX, hooks, or component exports, then review the formatted output before copying it back.
Does TypeScript Formatter type-check my code?
No. It focuses on layout and readability. Use `tsc`, your IDE, or CI checks for semantic type errors.
Is my TypeScript uploaded?
Formatting runs in the browser after the page loads, so quick snippets can be cleaned without signing in or installing an editor extension.
