|
By default, [useFetch](/api/composables/use-fetch) blocks navigation until its async handler is resolved.

|
`useLazyFetch` provides a wrapper around `useFetch` that triggers navigation before the handler is resolved by setting the `lazy` option to `true`.
|
|
|
|
|
|
|
|
> `useLazyFetch` has the same signature as `useFetch`.
