What problem does it solve?

TypeScript strict mode addresses the challenges of code readability, maintainability, and error prevention by enforcing stricter type rules.

Core Features & Use Cases

Type Safety: Eliminates use of any and enforces type checks, reducing runtime errors.
Code Readability: Enforces readonly and ReadonlyArray for immutability, and prefers type over interface for data structures.
Configuration: Offers comprehensive tsconfig.json settings to ensure all checks are enabled for strict type checking.
Immutability and Pure Functions: Promotes best practices for building robust and predictable code.
Schema-First Development: Provides guidance on defining and utilizing schemas for data structures and behavior contracts.
Branded Types: Facilitates type-safe primitives and prevents incorrect type assignments.

Quick Start

Set up TypeScript strict mode in your project by enabling all strict type checking options in your tsconfig.json.

FAQPage Schema

What does enabling TypeScript strict mode do for type safety?▼

Schema-first development in TypeScript involves defining schemas for data structures and behavior contracts upfront. This approach pairs with strict mode to guide type-safe implementations and predictable code behavior.

How do I set up TypeScript strict mode in an existing project?▼

You can set up TypeScript strict mode by enabling all strict type checking options within your tsconfig.json file. This configuration ensures comprehensive checks are activated for your entire project.

Should I use type or interface for data structures in strict TypeScript?▼

Branded types in TypeScript strict mode facilitate type-safe primitives and prevent incorrect type assignments. They help maintain strict type safety by ensuring primitives are structurally distinct.

Can I enforce immutability and pure functions using TypeScript strict mode?▼

TypeScript strict mode is applicable to any TypeScript project looking to enhance type checking and development standards. It requires configuring tsconfig.json to enable all available strict checks.

What is schema-first development in TypeScript strict mode?▼

How do branded types prevent incorrect type assignments in TypeScript?▼

Branded types in TypeScript strict mode facilitate type-safe primitives and prevent incorrect type assignments. They help maintain strict type safety by ensuring primitives are structurally distinct.
