Async
Abstraction for async operations that can be hooked into React.
yarn
npm
yarn add @corets/async
npm install --save @corets/async
Seamless React integrations are shipped inside separate packages:
Create an observable async operation:
import { createAsync } from "@corets/async"
const query = createAsync(async () => "some data")
Create an observable async operation without the factory function:
import { Async } from "@corets/async"
const query = new Async(async () => "some data")
Retrieve result from the last invocation:
query.getResult()
Retrieve probable error from the last invocation:
query.getError()
Retrieve all the details in a single call, contains values like
isRunning, isCancelled, result, etc.:query.getState()
Check if the async operation is being executed right now:
query.isRunning()
Check if the latest async invocation has been cancelled:
query.isCancelled()
Check if the latest async invocation errored:
query.isErrored()
Invoke async operation:
import { createAsync } from "@corets/async"
const query = createAsync(async (argument: number) => "some data")
const queryWithArguments = createAsync(async (argument: number) => `The value is ${argument}`)
const result = await query.run()
const anotherResult = await queryWithArguments.run(1337)
import { createAsync } from "@corets/async"
const query = createAsync(async (argument: number) => "some data")
const resultFromValue = await query.resolve("another value")
const resultFromPromise = await query.resolve(Promise.resolve("another value"))
const resultFromProducer = await query.resolve(async () => "another value")
Cancel current async invocation:
query.cancel()
const unsubscribe = query.listen((state) => console.log("async state changed", state))
