Queries and live results

Barq query results are live. When the database changes, results can update.

JavaScript

const allTasks = barq.objects(Task);
const openTasks = allTasks.filtered('done == false');
const newestFirst = openTasks.sorted('createdAt', true);

React

@barq/react wraps live results in hooks.

import { useQuery } from '@barq/react';

function TaskList() {
  const tasks = useQuery(Task);
  return null;
}

Native

The Native SDK exposes query and results APIs through barq_native/results.hpp and the main barq_native/sdk.hpp include.

Use results when a screen needs a collection that can change over time.
