Variable trackedTaskConst

Type declaration

• • <
        Return = unknown,
        Args extends unknown[] = unknown[],
        LocalTask extends TaskIsh<Args, Return> = TaskIsh<Args, Return>,
    >(
        context: object,
        task: LocalTask,
        thunk?: () => Args,
    ): TaskInstance<Return>

  • uses Resource to make ember-concurrency tasks reactive.

    ---

    Type Parameters

    • Return = unknown
    • Args extends unknown[] = unknown[]
    • LocalTask extends TaskIsh<Args, Return> = TaskIsh<Args, Return>

    Parameters

    • context: object
    • task: LocalTask
    • Optionalthunk: () => Args

    Returns TaskInstance<Return>

    Note

    ember-resources does not provide or depend on ember-concurrency. If you want to use task, you'll need to add ember-concurrency as a dependency in your project.

    Example

    When this.id changes, the task will automatically be re-invoked.

    import { tracked } from '@glimmer/tracking';
    import { restartableTask, timeout } from 'ember-concurrency';
    import { task as trackedTask } from 'reactiveweb/ember-concurrency';
    
    class Demo {
      @tracked id = 1;
    
      searchTask = restartableTask(async () => {
        await timeout(200);
        await fetch('...');
        return 'the-value';
      })
    
      last = trackedTask(this, this.searchTask, () => [this.id]);
    }
    Copy

    Available Properties:
     {{this.last.value}}
     {{this.last.isFinished}}
     {{this.last.isRunning}}
