TypeScript Formatter

Format TypeScript source files using Prettier WASM. Handles type annotations, interfaces, generics, decorators, and all modern TypeScript syntax — entirely offline.

Use Cases

  • Formatting TypeScript snippets from Stack Overflow
  • Standardizing code style before committing

Frequently Asked Questions

Does this type-check my code?

No. Prettier only handles formatting. Type checking requires a TypeScript compiler (tsc).
