A TypeScript development environment that compiles and executes .ts files in the browser with full type system support, including interfaces, type aliases, and cross-file imports.

Details

• Interfaces, type aliases, and type checking all work
• Cross-file imports resolve through TypeScript’s module system
• TypeScript is compiled and executed entirely in the browser
• Type mismatches are caught at compile time

Try it yourself

1. Edit the TypeScript files and add new interfaces
2. Try introducing a type error and see the compiler output
3. Add new .ts files with imports between them
