Build apps with TypeScript
All generated app code is TypeScript, from Zod schemas and Supabase types through to every component and route file. Goodspeed generates TypeScript as a standard part of every app, so the output is a working codebase from day one, not a scaffold you have to finish yourself.
WHAT GETS GENERATED
Built into every TypeScript build
Every app Goodspeed generates with TypeScript includes these production-ready patterns, wired together from the first build.
| Item | Description | Strength |
|---|---|---|
| tsconfig.json with strict mode | Generated tsconfig.json sets strict: true, noImplicitAny, and noUncheckedIndexedAccess to catch the largest class of generated-code bugs at compile time. | Configuration |
| tsc --noEmit gate in release script | scripts/release.mjs runs tsc --noEmit before EAS Build; any type error in generated code fails the build rather than shipping silently. | Quality |
| Zod schemas for runtime validation | lib/validation.ts exports emailSchema, passwordSchema, displayNameSchema, and feedbackSchema. The DevAgent generates additional app-specific schemas. | Validation |
| Typed event catalog | lib/events.ts exports a string-literal-union EVENTS catalog so every PostHog captureEvent call is checked against the declared event names at compile time. | Analytics |
| Supabase generated types | supabase gen types --project-id produces a Database type. All Supabase queries reference it so missing columns surface as type errors, not runtime 404s. | Backend |

REAL GENERATED CODE
A snippet from a TypeScript app the studio shipped
This pattern comes straight out of the production groundwork every Goodspeed app is generated on. The studio generates TypeScript code like this for every app in the pipeline, not a hello-world sample you have to grow into a real app.
Zod validation
// lib/validation.ts: common Zod schemas export const emailSchema = z.string().email('Invalid email address').trim().toLowerCase(); export const passwordSchema = z .string() .min(8, 'Password must be at least 8 characters') .max(128, 'Password must be at most 128 characters') .regex(/[A-Z]/, 'Password must contain an uppercase letter') .regex(/[0-9]/, 'Password must contain a number');

USE CASES BUILT ON TYPESCRIPT
Where this stack ships
These app types use TypeScript as part of the generated stack. Each link goes to a full spec page with capabilities, scored ideas, and a pipeline walkthrough.
- Build a Habit Tracker appHabit trackers live or die on the loop: cue, routine, reward. Goodspeed generates a complete React Native habit tracker with streaks, reminders, and progress visualization, backed by Supabase so your HABIT TRACKER APP
- Build a Meal Planner appMeal planner apps stall at the same place: you can log a meal but the app won't generate a shopping list or track your targets across the week. Goodspeed generates the full stack, recipes to pantry syMEAL PLANNER APP
- Build a Recipe Organizer appRecipe apps that survive in the App Store do more than display cards. They index, scale, substitute, and remember what worked. Goodspeed generates a complete recipe organizer with ingredient scaling, RECIPE APP
- Build a Language Practice appLanguage apps that stick use spaced repetition for vocabulary and real speaking practice to build confidence. Goodspeed generates both in a single build: an SRS flashcard engine, a speaking drill modeLANGUAGE LEARNING APP
- Build a Meditation App appMeditation apps need guided audio, session tracking, and the kind of streak mechanics that make a daily habit stick. Goodspeed generates all three, including a guided session player, a mindfulness jouMEDITATION APP
