The useGet Method ​

The useGet method takes the work out of watching an "id" variable and retrieving individual records from the API server.

Overview of Features ​

• Auto-Updating - change the id and it does the rest.
• Fall-Through Cache - Always pulls from the store while new data is fetched.
• Easy Request State - Pending request state is built in.
• SSR Friendly - Data can load on the server and hydrate on the client.

Usage ​

You can call useGet directly from the store. the advantage being that you don't have to provide the store in the params, as shown here:

interface Props {
  id: string | number
}
const props = defineProps<Props>()

const { api } = useFeathers()
const id = computed(() => props.id)

const { data: user, isPending, error } = api.service('users').useGet(id)

For a client-only solution, you can just use the getFromStore method:

interface Props {
  id: string | number
}
const props = defineProps<Props>()

const { api } = useFeathers()
const id = computed(() => props.id)

const user = api.service('users').getFromStore(id)

API ​

useGet(id, params) ​

• id {MaybeRef string | number} the id of the record to retrieve. Can be a computed/ref to enable automatic updates to the returned data.
• params {Object} a combined Feathers Params object and set of options for configuring behavior of useGet.
  • query {Object} a Feathers query object.
  • clones {Boolean} returns result as a clone. See Querying Data
  • temps {Boolean} enables retrieving temp records. See Querying Data
  • watch {boolean} can be used to disable the watcher on id
  • immediate {boolean} can be used to disable the initial request to the API server.

Returned Object ​

• id {Ref number | string} is a ref version of the id that was provided as the first argument to useGet. Modifying id.value will cause the data to change.
• params {Params} is a ref version of the params. Params are not currently watched for useGet.
• data {Computed Object} the record returned from the store.
• ids {Ref Array} is a list of ids that have been retrieved from the API server, in chronological order. May contain duplicates.
• get {Function} similar to store.get. If called without any arguments it will fetch/re-fetch the current id. Accepts no arguments.
• request {Promise} stores the current promise for the get request.
• requestCount {Ref number} a counter of how many requests to the API server have been made.
• getFromStore {Function} the same as store.getFromStore.
• isPending {Computed boolean} returns true if there is a pending request. While true, the data will continue to hold the most recently-fetched record.
• hasBeenRequested {Computed boolean} returns true if any record has been requested through this instance of useGet. It never resets.
• hasLoaded {Computed boolean} is similar to isPending but with different wording.
• error {Computed error} will display any error that occurs. The error is cleared if another request is made or if clearError is called.
• clearError {Function} can be used to manually clear the error.

Only Query Once Per Record ​

The simplest way to only query once per record is to set the skipGetIfExists option to true during configuration.

You can also use the useGetOnce method to achieve the same behavior for individual requests.
