Generics, combined with conditional types can make for an incredibly powerful combination. When you look at things the right way, you can ask very useful questions about your types that allow you to build the precise API you want.
This post introduces a middleware approach that allows efficient data refetching. The middleware enables the attachment of query keys and server functions, enhancing scalability and flexibility.
What if we could mutate data *and* get all the data back we need to properly update the UI in just one network round-trip?
I can easily imagine a job interview question being “What’s the difference between TypeScript and Zod and in what circumstances do you need each?” They are both type validation libraries. Would you ever need both? The short answer is that TypeScript is great but can’t help you at runtime, where you might get data from […]
The `satisfies` keyword allows you to assert that a certain value “satisfies” a given type, while preventing a wider type from being inferred.
What is the difference between ESLint and TypeScript? Perhaps that feels like a strange question as ESLint is a, uhm, linter, and TypeScript is a language that compiles to JavaScript. Josh Goldberg writes how there is some overlap: While ESLint and TypeScript operate differently and specialize in different areas of code defects, there is some […]
TanStack Query, or react-query, simplifies client-side data fetching with features like caching, automatic re-fetching, and error handling. It integrates smoothly with TanStack Router, allowing efficient prefetching and loading states using hooks like useSuspenseQuery.
TanStack Router is one of the most exciting projects in the web development ecosystem right now, and it doesn’t get nearly enough attention. It’s a fully fledged client-side application framework that supports advanced routing, nested layouts, and hooks for loading data. Best of all, it does all of this with deep type safety. This post […]
TanStack Router is a comprehensive JavaScript framework for client-side applications, emphasizing type-safe routing and navigation. It includes nested layouts and efficient data loading.
This post explores advanced TypeScript utilities for testing and verifying type correctness, akin to unit testing without extra setup.
