UseDas

UseDas is a term used in software development to denote a reusable hook or function designed to interface with a Data Access Service (DAS) from within component-based UIs. There is no single, canonical implementation; the name is used across different projects to reflect a pattern rather than a specific library.

In typical usage, useDas accepts a configuration describing the DAS endpoint, query, parameters, authentication, and caching preferences. It returns an interface including the current data, loading and error state, and utilities to refresh or update the query. Implementations may manage request cancellation, deduplication, and automatic refetching.

The hook aims to standardize data fetching logic, reduce boilerplate, and improve reactivity to data source changes. Depending on the project, useDas may integrate with custom DAS backends, REST endpoints, or GraphQL layers, and may offer pagination, optimistic updates, or cache hydration for server-side rendering.

Because useDas is not standardized, behavior and API surface vary by project. Developers should consult project documentation to understand its exact inputs and outputs. It is often compared to other data-fetching hooks such as SWR or React Query but is distinct in naming and specific DAS integration.
