Why TypeScript?

TypeScript has become the industry standard for professional JavaScript development. We help teams leverage TypeScript to build more maintainable, scalable applications:

Catch bugs at compile time - Type checking prevents runtime errors before they reach production
Self-documenting code - Types serve as inline documentation that stays up-to-date
Modern language features - Use the latest ECMAScript features with confidence
Better tooling - Intelligent autocomplete, refactoring, and navigation in your IDE
Team confidence - Onboard new developers faster with clear contracts between components

Our TypeScript Services

Full-Stack Development

Build complete applications with TypeScript across the stack:

Frontend: React, Next.js, Vue with full type safety
Backend: Node.js, Express, Fastify with typed APIs
Mobile: React Native with TypeScript
Desktop: Electron applications

API Development

Create robust APIs with TypeScript:

RESTful APIs: Type-safe route handlers and validation with Express or Fastify
GraphQL: Schema-first development with type generation
Serverless: AWS Lambda functions with typed handlers and events
Real-time: WebSocket servers with Socket.io or native WebSocket APIs

Here's an example of type-safe API development:

// Type-safe request handler with validation
interface CreateUserRequest {
  email: string;
  name: string;
  role: 'admin' | 'user';
}

interface User extends CreateUserRequest {
  id: string;
  createdAt: Date;
}

async function createUser(req: CreateUserRequest): Promise<User> {
  // TypeScript ensures we handle all required fields
  const user: User = {
    id: generateId(),
    email: req.email,
    name: req.name,
    role: req.role,
    createdAt: new Date(),
  };

  await db.users.insert(user);
  return user;
}

Migration & Modernization

Incrementally adopt TypeScript in existing JavaScript projects:

Gradual migration: Convert files one at a time without disrupting development
Type definitions: Add .d.ts files for untyped libraries
Strict mode adoption: Progressively enable stricter compiler options
Team training: Help your developers learn TypeScript best practices

Our Process

1. Discovery We understand your application architecture, team structure, and development workflow. We identify areas where TypeScript will provide the most value.

2. Architecture We design type systems that match your domain model. We establish patterns for API types, state management, and component props.

3. Development We write production-ready TypeScript code following best practices. We configure linting, formatting, and build tools for optimal developer experience.

4. Handover We document type patterns and conventions. We train your team on TypeScript features and provide ongoing support as needed.
