swrInit

swrinit is a term that can appear in discussions of SWR-based data fetching and in codebases that implement the Stale-While-Revalidate pattern. In many contexts, swrinit (often seen in camelCase as swrInit) refers to an internal initialization routine that sets up the SWR client, cache, or related configuration. It is not a universal, public API across all SWR implementations, and its presence and exact form can vary between projects.

The typical role of a swrinit routine is to prepare the data-fetching layer for use. This can include creating or loading a shared cache, applying default options (such as revalidation intervals, deduplication behavior, and error handling), and wiring together core components like the fetcher, cache, and configuration providers. The function helps ensure consistent behavior across components that rely on SWR hooks and mechanisms.

Usage patterns for swrinit vary. In some libraries, it is invoked during application startup or when a global configuration is applied, so that subsequent useSWR calls share a common cache and settings. In other cases, initialization may be implicit or handled by a higher-level provider, with swrinit existing as an internal helper function rather than a public API.

Because the exact meaning, signature, and visibility of swrinit differ by project, developers should consult the specific library or codebase documentation to understand how initialization is implemented and how it relates to the public SWR API (such as useSWR, SWRConfig, and mutate).
