Frequently Asked Questions
Common questions about Typescript Formatter formatting answered
Yes, our TypeScript formatter is completely free with no registration required. All processing happens in your browser.
Yes, our formatter fully supports all TypeScript-specific constructs including interfaces, type aliases, generics, enums, decorators, and utility types.
Yes, the formatter handles TSX/JSX syntax correctly, including component props, angle bracket type assertions, and generic components in JSX.
The formatter produces clean, consistent output following widely accepted TypeScript formatting conventions. You can adjust settings to closely match your preferred code style.
You can customize indentation, semicolon usage, quote style, trailing commas, brace placement, and how interfaces and type literals are laid out.
Interfaces and type aliases get brace-on-same-line with 2-space member indent; union types break one member per line when exceeding the print width (string | number | Record<string, unknown>); generics preserve spacing rules (Array<T>, not Array <T>); and enum members align on the = sign when the enum spans multiple lines.
Yes - import type { X } statements (which erase at compile time, per TypeScript 3.8) are grouped separately from value imports and never merged with them, because merging would change the emitted JS. Type-only constructs (satisfies, as const, infer) keep their operand spacing exactly - they bind tightly.
No, by construction: only whitespace, line breaks, and semicolon/quote normalization per option occur, all of which are syntax-preserving under the TypeScript grammar. Decorators keep their position relative to export modifiers (an area where AST printers historically differed); if the input parsed, the formatted output parses to the same AST.
