You can directly query Cube using the JSON query format via the REST (JSON) 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 the Cube API Gateway, and retrieve and process data. It is designed to work with existing charting libraries including Chart.js, D3.js, and more.

​
Cube JavaScript Client

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 compare date range queries or data blending queries. Learn more in the documentation for the @cubejs-client/core package.

​
Cube Angular Package

The package provides convenient tools to work with Cube in Angular: Modules. Inject CubeClientModule and CubeClient into your components and services to get access to @cubejs-client/core API. Subjects. Use RxJS Subject and query to watch changes.

​
Example Usage

Here are the typical steps to query and visualize analytical data in Angular:
  • Import @cubejs-client/core and @cubejs-client/ngx packages. These packages provide all the necessary methods and convenient Angular 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: with NODE_ENV unset the API accepts requests with no token, and development mode bypasses authentication outright, so both are intended for local development machines only.
  • Query data from Cube Backend and Transform data for visualization. Use CubeClient to load data. The client accepts a query, which is a plain JavaScript object. See Query Format for details.
  • Visualize the data. Use tools of your choice to draw charts and create visualizations.
See an example of using Cube with Angular and Chart.js library. Note that you can always use a different charting library that suits your needs:

Getting Started

You can install Cube JavaScript Client and the Angular package with npm or Yarn:
Now you can build your application from scratch or connect to one of our supported data visualization tools.
