Custom Logger

If you want to change how information is logged by React Query, you can set a custom logger when creating a QueryClient.

tsx
const queryClient = new QueryClient({
logger: {
log: (...args) => {
// Log debugging information
},
warn: (...args) => {
// Log warning
},
error: (...args) => {
// Log error
},
},
})

Deprecated

Custom loggers have been deprecated and will be removed in the next major version. Logging only has an effect in development mode, where passing a custom logger is not necessary.
