TypeScript adds static typing to JavaScript, catching errors before runtime and enabling better IDE support. Our TypeScript code generator uses AI to create strongly-typed code with proper interfaces, type aliases, generics, and union types. Whether you need type definitions for API responses, utility functions with type safety, or complex generic types, describe your requirements and get production-ready TypeScript code with comprehensive type annotations.
Perfect for frontend developers building React or Angular apps, backend engineers creating Node.js APIs with Express, library authors publishing typed packages, or JavaScript developers migrating to TypeScript. The generated code follows TypeScript best practices including strict mode compliance, proper type inference, and avoiding "any" types.
Generate interfaces for data shapes, type aliases for complex types, union and intersection types, mapped types, conditional types, or utility type implementations. Create type definitions for API responses with nested objects, define discriminated unions for state management, build generic interfaces for reusable components, or generate type guards for runtime type checking. Perfect for maintaining type safety across large codebases.
Example tasks: "Create interface for user profile with optional fields", "Generate type guard to check if object is User type", "Build utility type to make all properties readonly and optional". The AI understands TypeScript's advanced type system including keyof, typeof, and template literal types.
Create strongly-typed React functional components with props interfaces, hooks with proper type inference (useState, useEffect, useContext), custom hooks with generic types, or component wrappers with higher-order component types. Generate code for forms with typed handlers, API data fetching with typed responses, context providers with typed values, or Redux actions and reducers with full type safety.
If migrating JavaScript React code, use our JavaScript to TypeScript converter to add types automatically, or TypeScript to JavaScript converter to remove types for compatibility.
Generate typed Express middleware with Request/Response extensions, create type-safe route handlers, build typed database models with Prisma or TypeORM, implement typed API clients, or create DTOs with class-validator decorators. Includes proper async/await typing, error handling with custom error classes, and typed configuration objects for environment variables.
Create generic functions that work with multiple types, build type-safe array utilities, implement promise wrappers with proper typing, generate object manipulation helpers with keyof constraints, or create typed event emitters. Perfect for building reusable libraries or utility packages with full type inference support.
Generate generic functions with type constraints, create generic classes for data structures, implement generic interfaces for services, use multiple type parameters, add default type parameters, or build recursive generic types. Create type-safe wrappers for API calls, generic repository patterns for databases, or reusable component prop types that adapt to different data shapes.
Example: "Create generic function to fetch data from API with typed response, error type, and query parameters"
Create conditional types that change based on type parameters, build template literal types for string manipulation at type level, use infer keyword for extracting types, implement distributive conditional types, or create utility types that transform object shapes. Perfect for building flexible type systems that adapt to different scenarios.
Example: "Create type that extracts return type from function", "Build type that converts snake_case keys to camelCase"
Generate discriminated union types for state machines, implement exhaustive switch statements with never type checks, create tagged unions for API responses, build type-safe reducers for state management, or implement the visitor pattern with types. Ensures all possible cases are handled at compile time, preventing runtime errors.
Get fully type-safe code by following these best practices
Describe the shape of your data precisely: "user object with id number, name string, email string, roles array of strings, optional avatar string". The more specific you are about types, the better the generated code will match your needs. Mention nullable, optional, or readonly modifiers.
Good: "Create interface for user"
Better: "Create interface User with required id:number, name:string, optional email:string"
Specify if you're using React, Angular, Vue, or Node.js: "React functional component with TypeScript", "Angular service with dependency injection types", "Express middleware with Request/Response types". This ensures proper imports and framework-specific type usage.
The generator knows framework-specific types like React.FC, NextPage, or Express.RequestHandler
Ask for generic implementations when you need reusability: "generic function that works with any object type", "generic API client for different endpoints", "generic form handler with any data shape". This creates flexible, type-safe code that adapts to different use cases.
Generic types prevent code duplication while maintaining full type safety
Don't ask for "any" types unless absolutely necessary. Instead request "unknown" for truly dynamic data you'll type-check later, or use generic type parameters. The generator prefers strict typing and will create proper types when given enough information about your data structures.
Strict typing catches errors at compile time, saving debugging time later
Converting existing JavaScript to TypeScript? Our converter handles the translation:
Generate typed tests and utility type functions
Generate typed Jest tests with proper type assertions, create mock implementations with correct types, build typed test utilities, implement custom matchers with type support, or write integration tests with full type safety. Includes proper typing for async tests, mock functions, and test fixtures.
Create type guard functions with "is" predicates, build assertion functions with "asserts" keyword, implement branded types for primitive values, generate Zod or Yup schemas with TypeScript inference, or create runtime validators that match compile-time types. Perfect for validating external data from APIs or user input.
Describe what you want to build in plain English, select TypeScript as your target language, and click "Generate Code". Our AI will create clean, functional TypeScript code based on your description.
