TypeScript

Building Scalable Frontend Systems

My use of TypeScript is central to building large-scale, maintainable frontend applications. By adding a static type system on top of JavaScript, I can catch errors early in the development process, improve code clarity, and enable powerful features like autocompletion and refactoring.

This entire portfolio website is a testament to my commitment to TypeScript, where it is used throughout the React and Gatsby codebase to ensure every component, page, and utility function is strongly typed.

Improving the Developer Experience

Beyond just catching bugs, I leverage TypeScript to create a superior developer experience for myself and my team. Well-defined types serve as a form of documentation, making the codebase easier to understand and onboard new developers. It allows for confident refactoring and ensures that data structures are consistent across the application.

Key Competencies

• Static Typing: Proficient in using TypeScript's type system, including interfaces, generics, enums, and utility types.
• React with TypeScript: Building strongly-typed React components, managing state, and handling props with full type safety.
• Configuration: Setting up and configuring tsconfig.json for different project needs, including strict mode compliance.
• Type Declaration Files: Understanding and using type declaration (.d.ts) files to work with third-party JavaScript libraries that do not have native TypeScript support.
• Migration: Experience in progressively migrating existing JavaScript codebases to TypeScript.
