import { injectQuery } from '@tanstack/angular-query-experimental'

// Make a specific query retry a certain number of times
const result = injectQuery(() => ({
  queryKey: ['todos', 1],
  queryFn: fetchTodoListPage,
  retry: 10, // Will retry failed requests 10 times before displaying an error

import {
  QueryCache,
  QueryClient,
  QueryClientProvider,
} from '@tanstack/angular-query-experimental'

const queryClient = new QueryClient({
  defaultOptions: {
    queries: {
      retryDelay: (attemptIndex) => Math.min(1000 * 2 ** attemptIndex, 30000),
    },
  },
})

bootstrapApplication(AppComponent, {
  providers: [provideTanStackQuery(queryClient)],
})

Though it is not recommended, you can obviously override the retryDelay function/integer in both the Provider and individual query options. If set to an integer instead of a function the delay will always be the same amount of time:

const result = injectQuery(() => ({
  queryKey: ['todos'],
  queryFn: fetchTodoList,
  retryDelay: 1000, // Will always wait 1000ms to retry, regardless of how many retries
}))
