This Part 1 (of a 2-part series) is a practical, hands-on, applicable approach to database indexes. We’ll cover what B Trees are with a focus on deeply understanding, and internalizing how they store data on disk, and how your database uses them to speed up queries. This will set us up nicely for part 2, […]

Zustand is a minimal, but fun and effective state management library which just may improve your render performance.

The `satisfies` keyword allows you to assert that a certain value “satisfies” a given type, while preventing a wider type from being inferred.

TanStack Start enhances the TanStack Router by adding a server layer that improves performance through server-side rendering (SSR) and isomorphic loaders.

If it can go in a Docker, Fly can host it, and they’ll help you with that. Adam Rackis takes a look at the platform and shows off all the things he likes about it.

Drizzle ORM is a powerful object-relational mapper that combines SQL capabilities with a strongly typed API, enabling complex queries. Here we’ll look at using it’s ability to help with migrations, both code-first and database-first.

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.

The post discusses the drawbacks of null references in programming and introduces the Optional type as a solution, particularly in Java. The Optional type helps avoid null reference exceptions by allowing safe interaction with absent values using methods like ifPresent, ifPresentOrElse, map, and flatMap.
