TypeScript Tips for Large Scale Applications

TypeScript helps teams build reliable applications, but poor type structures can create complexity quickly.

Prefer Types Over Any

type User = {
  id: string;
  name: string;
  email: string;
};

Strong typing improves editor support and reduces runtime bugs.

Organize Shared Types

• Create reusable domain models.
• Avoid duplicate interfaces.
• Use utility types wisely.
• Keep types predictable.

Good TypeScript feels invisible because everything just works.
