katanakit-js / environmentManager

Variable: environmentManager

const environmentManager: {
  isServer: () => boolean;
  setIsServer: void;
};

Defined in: node_modules/.bun/@tanstack+query-core@5.104.1/node_modules/@tanstack/query-core/build/modern/environmentManager.d.ts:24

Manages how TanStack Query detects whether the current runtime should be treated as server-side, which disables scheduling refetch timers and changes the default retry count and gcTime. By default, the detection treats a missing window (or the presence of a Deno global) as server.

Override this for runtimes where that default detection would give the wrong answer — for example, a Service Worker, where window is undefined even though the environment should behave like a client.

isServer: () => boolean;
