Async Tasks

• It is used to manage async tasks with redux state.

Usage pattern

Activate reducer on slice (Required)

import * as asyncTasks from '@dreamworld/async-tasks';
import { store } from "path/to/store";

asyncTask.init(store);

Use Generator function to run any async task

Foreground task

import { run } from '@dreamworld/async-tasks';

try {
  const result = yield call(run, taskId, fn, timeoutMillis);
} catch (e) {
  //handle error
}

Background task

import { run } from '@dreamworld/async-tasks';

try {
  const taskId = yield fork(run, taskId, fn, timeoutMillis);
  yield cancel(taskId);
} catch (e) {
  //handle error
}

To retrieve the result of a Task from another Saga

import { taskResult } from '@dreamworld/async-tasks';

try {
  const result = yield call(taskResult, taskId);
} catch (e) {
  //if Task failed.
}

Selectors

• Task get(id): Returns Task of given id.
• String status(id): Returns current status of given taskId
• Object result(id): Returns result of given taskId
