Understanding module resolution in TypeScript
Learn how TypeScript module resolution maps imports to real files, how node16/nodenext and bundler strategies differ, and how to avoid "cannot find module" errors in Node.js and browser builds.
A Look into Valdi: Snapchat's UI Framework
Explore Valdi, Snapchat's open-source cross-platform UI framework that compiles TypeScript directly to native iOS, Android, and macOS code. Learn how it achieves native performance without JavaScript bridges, why Snapchat built it instead of using React Native, and whether it's the right choice for your next project.
Tuple Types in TypeScript
Learn how TypeScript's tuple types enforce fixed-length arrays with position-specific types. Master optional elements, rest elements, labeled tuples, and readonly tuples for type-safe structured data modeling.
Rest Parameters and Spread Syntax in TypeScript
Learn how TypeScript's rest parameters and spread syntax enable type-safe variadic functions. Master collecting arguments into arrays, spreading elements as parameters, and building flexible APIs with compile-time type checking.
Type Assertions and Type Casting in TypeScript
Learn how TypeScript's type assertions work and when to use them safely. Understand as const for literal types, avoid common assertion pitfalls, and master the difference between assertions and type guards.
TypeScript Types vs Interfaces
Learn the practical differences between TypeScript types and interfaces, how they handle extension and composition, and when to choose one over the other in real projects.
Interfaces in TypeScript
Learn how TypeScript interfaces define object shapes and enforce type contracts at compile time. Master interface extension, function signatures, and understand the differences between interfaces and type aliases.
Index Signatures in TypeScript: Type-Safe Dynamic Objects
Learn how to use TypeScript index signatures to type dynamic object keys safely, combine them with known properties, and build flexible, well-typed data structures.
Optional Properties and Null Handling in TypeScript
Learn how TypeScript's optional properties and strict null checks prevent null reference errors at compile time. Master null handling patterns with optional chaining, nullish coalescing, and type narrowing techniques.
Understanding readonly in TypeScript
Learn how TypeScript's readonly modifier prevents property mutations at compile time. Understand the differences between readonly, const, and Object.freeze(), and build type-safe immutable data structures without runtime overhead
Understanding TypeScript Conditional Types and infer
Learn how TypeScript conditional types and the infer keyword enable powerful type logic, pattern matching, and adaptive type transformations.
Understanding TypeScript's Satisfies Operator
Learn how TypeScript’s `satisfies` operator ensures type safety without widening unions. Validate types and preserve exact inference for cleaner code.
Getting Started with Typia
Learn how to use Typia for fast and type-safe validation in TypeScript projects. This guide covers setup, validation rules, custom tags, and integration with Express.
