# Angular

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

You can directly query Cube using the
JSON [query format](/product/apis-integrations/rest-api/query-format) via the [REST API](/product/apis-integrations/rest-api/reference)
or
[WebSockets](/product/apis-integrations/recipes/real-time-data-fetch#web-sockets)
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](/product/apis-integrations/javascript-sdk/reference/cubejs-client-core#load) from Cube Backend or
subscribe to
[real-time updates](/product/apis-integrations/recipes/real-time-data-fetch)
regardless of the protocol, be it HTTP or WebSockets.

**Transform data for visualization.** You can
[pivot](/product/apis-integrations/javascript-sdk/reference/cubejs-client-core#pivot) the result set to display
as a [chart](/product/apis-integrations/javascript-sdk/reference/cubejs-client-core#chartpivot) or as a
[table](/product/apis-integrations/javascript-sdk/reference/cubejs-client-core#tablepivot), split into
[series](/product/apis-integrations/javascript-sdk/reference/cubejs-client-core#series) or
[table columns](/product/apis-integrations/javascript-sdk/reference/cubejs-client-core#tablecolumns).

**Simplify work with complex query types.** You can build
[drill down](/product/apis-integrations/javascript-sdk/reference/cubejs-client-core#drilldown) queries and
[decompose](/product/apis-integrations/javascript-sdk/reference/cubejs-client-core#decompose) the results of
[compare date range queries][ref-compare-date-range]
or [data blending](/product/data-modeling/concepts/data-blending) queries.

[Learn more](/product/apis-integrations/javascript-sdk/reference/cubejs-client-core) 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`](/product/apis-integrations/javascript-sdk/reference/cubejs-client-ngx#api) into your
components and services to get access to `@cubejs-client/core` API.

**Subjects.** Use [RxJS Subject](/product/apis-integrations/javascript-sdk/reference/cubejs-client-ngx#api) 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](http://localhost:4000/cubejs-api/v1).
  The client is also initialized with an [API token](/product/auth), but it
  takes effect only in [production](/product/deployment/production-checklist).
- **Query data from Cube Backend and Transform data for visualization.** Use
  [`CubeClient`](/product/apis-integrations/javascript-sdk/reference/cubejs-client-ngx#api) to load data. The
  client accepts a query, which is a plain JavaScript object. See
  [Query Format](/product/apis-integrations/rest-api/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:

  style={{
    width: "100%",
    height: 500,
    border: 0,
    borderRadius: 4,
    overflow: "hidden",
  }}
  sandbox="allow-modals allow-forms allow-popups allow-scripts allow-same-origin"
></iframe>

## Getting Started

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

```bash
# npm
npm install --save @cubejs-client/core @cubejs-client/ngx

# Yarn
yarn add @cubejs-client/core @cubejs-client/ngx
```

Now you can build your application from scratch or connect to one of our
[supported data visualization tools](/product/configuration/visualization-tools).
