TypeScript Input

interface User {
name: string;
age: number;
roles?: string[];

class UserService {
private users: User[] = [];
add(user: User): void {
this.users.push(user);
}
}

Formatted

interface User  {

age: number;

roles?: string[];
}

class UserService  {

private users: User[] = [];

add(user: User): void  {

this.users.push(user);
  }
}

This is a lightweight indentation-based formatter, not a full AST-based formatter like Prettier — review output for complex generic types.

This tool formats and beautifies TypeScript code - applying consistent indentation, spacing, and line breaks - making messy or minified TypeScript much easier to read and review, similar to what a code formatter like Prettier does automatically in an editor.

Frequently asked questions

Does formatting change how my TypeScript code behaves? expand_more

No - formatting only adjusts whitespace, indentation, and line breaks for readability. The logic, types, and behavior of the code are completely unchanged.

Does it check for TypeScript type errors? expand_more

This tool focuses on formatting/beautifying code, not type-checking - use your TypeScript compiler or IDE for actual type error detection.

Can I use this for plain JavaScript too? expand_more

TypeScript is a superset of JavaScript, so standard JavaScript code will generally format correctly through a TypeScript formatter as well.
