Type-Safe Full-Stack Development
TypeScript everywhere - API, frontend, database schemas, and more
Everything You Need
Our comprehensive starter kit includes all the features you need to build, launch, and scale your SaaS application
End-to-End Type Safety
Every line of code is TypeScript with strict mode enabled. From database entities to API contracts to frontend components - your types flow seamlessly through the entire stack.
Type-Safe API Communication
Automatically generated TypeScript types from your API endpoints. Change your backend and get compile-time errors in your frontend. No more runtime surprises from API changes.
Database Types with TypeORM
TypeORM entities provide full type safety for your database operations. Migrations are type-checked. Query builders have full IntelliSense. Refactor your schema with confidence.
Runtime Validation with Zod
Zod schemas provide runtime validation that automatically infers TypeScript types. Validate API inputs, form data, and environment variables with a single source of truth.

Catch Bugs Before They Ship
TypeScript catches type errors at compile time, not in production. Studies show TypeScript prevents 15% of bugs that would reach production. Ship with confidence knowing your types are correct.
IDE Support That Feels Like Magic
Full IntelliSense everywhere - autocomplete, parameter hints, inline documentation. Navigate your codebase with go-to-definition. Refactor with automatic symbol renaming across files.
Refactor Without Fear
Change interfaces, rename properties, or restructure your data models. TypeScript ensures every usage is updated. Large-scale refactoring that would take days in JavaScript takes minutes.
Code That Documents Itself
Types serve as inline documentation that's always up to date. New developers understand your codebase faster. Function signatures tell you exactly what to pass and what you'll get back.
Frequently Asked Questions
Everything you need to know about our SaaS starter kit
Do I need to be a TypeScript expert to use this starter?
No, basic TypeScript knowledge is sufficient. If you know JavaScript, you can gradually learn TypeScript features as you go. Our codebase uses straightforward TypeScript patterns without overly complex type gymnastics. The strict mode helps catch errors early.
Can I disable TypeScript if I prefer JavaScript?
While the starter is built with TypeScript in mind, you can rename .ts files to .js and adjust the configuration. However, we strongly recommend keeping TypeScript as it prevents many bugs and improves the development experience significantly.
How are API types kept in sync between frontend and backend?
We use shared type definitions and automated type generation from your API endpoints. When you change your backend API, TypeScript will immediately flag any frontend code that needs updating. This prevents runtime errors from API contract changes.
What TypeScript features are used in the codebase?
We use modern TypeScript features including strict null checks, template literal types, conditional types, mapped types, and utility types. However, we avoid overly complex type patterns that would make the code hard to understand.
How does TypeScript work with the database?
TypeORM provides full TypeScript support with decorators for entities and type-safe query builders. Your database schema is reflected in TypeScript types, so any schema changes are caught at compile time.
Is the TypeScript configuration customizable?
Yes! While we provide a strict TypeScript configuration for maximum safety, you can adjust the tsconfig.json to your preferences. You can relax certain rules if needed, though we recommend keeping strict mode enabled.
How do environment variables work with TypeScript?
Environment variables are fully typed using Zod schemas. This means you get compile-time checking and runtime validation of all environment variables. Missing or incorrectly typed env vars are caught before your app starts.
Does TypeScript slow down development?
Initially, TypeScript might feel slower as you write types. However, it speeds up development significantly by catching bugs early, providing better IDE support, and making refactoring safer. The time invested in types pays off quickly.
