| ```ts |
| 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 |
| })) |
| ``` |
|
|
| [//]: # 'Example' |
| [//]: # 'Example2' |
|
|
| ```ts |
| // Configure for all queries |
| 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)], |
| }) |
| ``` |
|
|
| [//]: # 'Example2' |
|
|
| 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: |
|
|
| [//]: # 'Example3' |
|
|
| ```ts |
| const result = injectQuery(() => ({ |
| queryKey: ['todos'], |
| queryFn: fetchTodoList, |
| retryDelay: 1000, // Will always wait 1000ms to retry, regardless of how many retries |
| })) |
| ``` |
|
|
| [//]: # 'Example3' |
|
