Challenges of Building UIs, Side Effects, and Live Store Data Layer

The chapter delves into challenges related to building performing UIs, managing side effects, and introduces the development of a new data layer called Live Store that handles concurrent data edits, syncing, and persistence. It explores the use of effect capabilities in building the library, synchronous queries with Livestore, and the importance of workers in handling persistence tasks in even single-tab cases. The discussion also covers functional programming effects, local-first philosophy, distributed systems complexities, and the impact of TypeScript, WebAssembly, and AI advancements on the technological landscape and developer choices.
