Infinite queries in React Query, often used in paginated lists or infinite scrolls, allow for continuous data fetching. A bug found in this feature caused queries to restart from the beginning if a page fetch fails during a retry. This article explains how infinite queries work in order to explain how the bug happened, along with the fix, which involves modifying the infinite query behavior to retain the state of the loop, preventing it from restarting from the beginning during retries.

A DIFFERENT WAY TO THINK ABOUT TYPESCRIPT

This post proposes a new way to understand TypeScript's type system. It suggests thinking of types as sets of possible values they can construct. This means a string type represents the infinite set of all possible character permutations, and a number type represents the infinite set of all possible digit permutations. TypeScript's features like intersection, union, and type introspection can be understood as operations on these sets.
