ngx-tableau

ngx-tableau is an Angular module that allows to embed a Tableau report in an Angular webapp. You can see a working DEMO here.

Prerequisites

  • NodeJS version 16+ for 2.x versions
  • NodeJS version 10+ for 1.x versions

Getting started

Install ngx-tableau library using npm:

npm install ngx-tableau

Add TableauModule to imports section of your app.module.ts file:

import { TableauModule } from 'ngx-tableau';

@NgModule({
  declarations: [AppComponent],
  imports: [BrowserModule, TableauModule],
  bootstrap: [AppComponent],
})
export class AppModule {}

The most basic use is just passing a public Tableau visualization URL.

<!-- Using report URL directly on HTML -->
<ngx-tableau
  tableauVizUrl="https://public.tableau.com/views/HurricaneMichaelPowerOutages/Outages"
></ngx-tableau>

<!-- Using report URL defined on view controller -->
<ngx-tableau [tableauVizUrl]="tableauVizUrl"></ngx-tableau>

Configuration options

You can pass configuration options to ngx-tableau using the following inputs to the component:

tableauVizUrl

URL of a Tableau visualization to embed. Perfect for public visualizations or if you know the exact URL of the Tableau visualization. If this input is defined, the component will ignore the configuration options serverUrl and report. Example:

<ngx-tableau
  tableauVizUrl="https://public.tableau.com/views/AroundtheAntarctic/MapClean"
></ngx-tableau>

tableauJsApiUrl

URL of Tableau JavaScript API v2, to be able to load a custom version (public or from your own Tableau Server). The default Tableau JavaScript API loaded if this variable is not set is https://public.tableau.com/javascripts/api/tableau-2.9.1.min.js. Example:

<ngx-tableau
  tableauJsApiUrl="https://public.tableau.com/javascripts/api/tableau-2.9.1.min.js"
  tableauVizUrl="https://public.tableau.com/views/AroundtheAntarctic/MapClean"
></ngx-tableau>

options

Visualization options for the Tableau view available in the JavaScript API. It should be a JSON object. Example:

import { VizCreateOptions, ToolbarPosition } from 'ngx-tableau'

// Options
options: VizCreateOptions = {
  hideTabs: true,
  hideToolbar: false,
  disableUrlActionsPopups: true,
  toolbarPosition: ToolbarPosition.TOP,
  onFirstInteractive: (event) => {
    console.log('On first interactive event!', event);
  }
};
<ngx-tableau
  tableauVizUrl="https://public.tableau.com/views/SuperSampleSuperstore/SuperDescriptive"
  [options]="options"
></ngx-tableau>

filters

Filters to pass to the Tableau visualization. It should be a JSON object. Example:

<ngx-tableau
  tableauVizUrl="https://public.tableau.com/views/SuperSampleSuperstore/SuperDescriptive"
  filters="{ Parameter3: 'Central' }"
></ngx-tableau>

serverUrl

URL of Tableau server. If this input is defined, it is mandatory to fill at least report input. Example:

<ngx-tableau
  serverUrl="https://public.tableau.com"
  report="AutonomousVehicles/AV"
></ngx-tableau>

report

The name of the workbook and the view ypu want to embed separated by a slash. Mandatory if using serverUrl. Example:

<ngx-tableau
  serverUrl="https://public.tableau.com"
  report="CityEyes/CityEyes"
></ngx-tableau>

ticket

If you want to embed a private Tableau visuzalization skipping sign in page for your end users, you should set up trusted authentication. Passing the obtained ticket to this option saves your users from having to sign in Tableau Server. Example:

<ngx-tableau
  serverUrl="https://myprivatetableau.mycompany.com"
  report="SomeWorkbook/SomeView"
  ticket="QUQub0EdSAaE39Eyg1oaLA==:9qT6oMvKUwXGr7TDpYKT9lvt"
></ngx-tableau>

site

If it is a multi-site site server you will need to pass the name of the site. If you are using trusted authentication take into account that you should pass a target_site attribute to the request to obtain the ticket or the ticket will not be valid to embed your visualization.

<ngx-tableau
  serverUrl="https://myprivatetableau.mycompany.com"
  report="myWorkbook/myView"
  ticket="QUQub0EdSAaE39Eyg1oaLA==:9qT6oMvKUwXGr7TDpYKT9lvt"
  site="mySite"
></ngx-tableau>

debugMode

Enables the debug mode of the component, which will show log traces in thde console.

<ngx-tableau
  tableauVizUrl="https://public.tableau.com/views/SuperSampleSuperstore/SuperDescriptive"
  [debugMode]="true"
></ngx-tableau>

Handling events

You can add or remove event listeners for the Tableau Viz object.

<ngx-tableau
  serverUrl="https://public.tableau.com/views/SuperSampleSuperstore/SuperDescriptive"
  (tableauVizLoaded)="handleOnTableauVizLoaded($event)"
></ngx-tableau>
import { TableauEvents } from 'ngx-tableau';

handleOnTableauVizLoaded = (tableauViz) => {
  console.log("Tableau viz loaded", tableauViz);

  tableauViz.addEventListener(TableauEvents.TAB_SWITCH, (event)=>{
    console.log(`Tab changed from '${event.getOldSheetName()}' to '${event.getNewSheetName()}'`, event)
  })
}

For a complete reference about Viz event types and specific handling, see the official documentation.
