TypeScript
TypeScript adds static typing to JavaScript, catching bugs at compile time instead of runtime. Every Goodspeed app is written in TypeScript for reliability, maintainability, and developer experience.
Why we chose TypeScript
Type safety prevents entire categories of bugs. When Goodspeed generates code, TypeScript ensures the output is structurally correct. When you extend the app later, types act as documentation and guard rails.

IntelliSense and autocomplete in editors
Self-documenting code through types
Refactoring safety with type constraints
Zod schema integration for runtime validation
Industry standard for modern JavaScript projects
