Loading

For Vue apps, the library includes VueRequestLoader, VueRequestLoaderFactory, and VueRequestBatchLoader, which use Vue refs to track loading state.

Registering the Vue Loader Factory

import { BaseRequest } from '@blueprint-ts/core/requests'
import { VueRequestLoaderFactory } from '@blueprint-ts/core/vue/requests'

BaseRequest.setRequestLoaderFactory(new VueRequestLoaderFactory())

Reading Loading State

const request = new ExpenseIndexRequest()

request.send()

const isLoading = request.isLoading()
// isLoading is a Ref<boolean> when using VueRequestLoaderFactory

Batch Loading

VueRequestBatchLoader can track the loading state of multiple requests. Use it when you want a single loading ref to reflect a batch of requests.

import { VueRequestBatchLoader } from '@blueprint-ts/core/vue/requests'

const batchLoader = new VueRequestBatchLoader(2)
batchLoader.startBatch(2)

const requestA = new ExpenseIndexRequest().setRequestLoader(batchLoader)
const requestB = new ExpenseIndexRequest().setRequestLoader(batchLoader)

requestA.send()
requestB.send()

const isLoading = batchLoader.isLoading()

If the batch will not complete (for example, when a chained request fails), call abortBatch() to stop waiting for the remaining requests:

batchLoader.abortBatch()
