Introduction for React Developers

Cube is visualization-agnostic, so you can build any user interface for your application.

You can directly query Cube Backend using JSON Query Format via HTTP API or WebSockets and visualize analytical data with tools of your choice. However, it's much easier to use the Cube JavaScript client and bindings for popular frameworks such as React, Angular, and Vue.

The client has methods to communicate with Cube API Gateway and retrieve and process data. It is designed to work with existing charting libraries including Chart.js, D3.js, and more.

The client provides methods to solve common tasks:

Abstract from the transport and query data. You can fetch data from Cube Backend or subscribe to real-time updates regardless of the protocol, be it HTTP or WebSockets.

Transform data for visualization. You can pivot the result set to display as a chart or as a table, split into series or table columns.

Simplify work with complex query types. You can build Drill Down queries and decompose the results of compareDateRange or Data Blending queries.

Learn more in the documentation for the @cubejs-client/core package.

The package provides convenient tools to work with Cube in React:

Hooks. You can add the useCubeQuery hook to functional React components to execute Cube queries.

Components. You can use QueryBuilder and QueryRenderer components to separate state management and API calls from your rendering code. You can also use CubeProvider and CubeContext components for direct access to Cube Client anywhere in your application.

Here are the typical steps to query and visualize analytical data in React:

  • Import @cubejs-client/core and @cubejs-client/react packages. These packages provide all the necessary methods and convenient React tools.
  • Create an instance of Cube JavaScript Client. The client is initialized with Cube API URL. In development mode, the default URL is http://localhost:4000/cubejs-api/v1. The client is also initialized with an API token, but it takes effect only in production.
  • Query data from Cube Backend. In functional React components, use the useCubeQuery hook to execute a query, which is a plain JavaScript object. See Query Format for details.
  • Transform data for visualization. The result set has convenient methods, such as series and chartPivot, to prepare data for charting.
  • Visualize the data. Use tools of your choice to draw charts and create visualizations.

See an example of using Cube with React and Chart.js library. Note that you can always use a different charting library that suits your needs:

You can install Cube JavaScript Client and the React package with npm or Yarn:

# npm
$ npm install --save @cubejs-client/core @cubejs-client/react

# Yarn
$ yarn add @cubejs-client/core @cubejs-client/react

Now you can build your project from scratch or generate a sample dashboard application with Cube Playground. You can also explore example applications built with Cube.
