Readable TypeScript code: 14 patterns for humans and AI

The text discusses the importance of writing readable and maintainable TypeScript and React code, especially in the context of AI-assisted development. The author emphasizes that code readability is crucial as it is often read more than it is written, and outlines several patterns and practices aimed at improving code clarity. Key practices include keeping functions and components short, using early returns instead of nested conditionals, avoiding unnecessary curly braces in single-line conditionals, defaulting to const for variable declarations, and modeling variants as discriminated unions. Additionally, the text advises pushing queries and mutations to the component level where they are used and maintaining a consistent use of patterns across the codebase for better scalability and ease of understanding by both human developers and AI agents. The author also highlights the use of tools like the Convex platform to ensure end-to-end consistency in codebases, promoting a seamless integration of database schemas and React components. These practices are intended to ensure the codebase remains scalable, trustworthy, and understandable, even as AI becomes more involved in code generation.
