createSharedExecutionComposable
Utility function to wrap any composables making sure they are only run once per execution scope so data can be shared globally throughout the execution code.
Usage
Shared Execution State
import { createSharedExecutionComposable } from '@serverless-use/core'
type MyState = {
name?: string
image?: string
profile?: string
}
export const useState = createSharedExecutionComposable(() => {
// This function will only be run once per execution
const state: MyState = {}
// this result will be automatically cached for the execution scope
// and returned anytime this composable is called
return { state }
})
Async Composable
WARNING
Generally it is best practice to keep composables synchronous and perform async calls as needed. For example this composable could return a function getData that is async and caches its response.
import { createSharedExecutionComposable } from '@serverless-use/core'
const useRemoteData = createSharedExecutionComposable(async () => {
return new Promise<{ data: string[] }>((resolve) => {
setTimeout(() => {
// fetch some async data here
const data = ['Falkor', 'Atreyu', 'Rockbiter']
resolve({ data })
}, 10)
})
})
// [ 'Falkor', 'Atreyu', 'Rockbiter' ]
const { data } = await useRemoteData()
