Extensions let you add unique features to dashboards or directly integrate them with applications outside Tableau. Adding extensions is easy; you incorporate them into dashboard layouts just like other dashboard objects.
Extensions expand dashboard functionality with the help of web applications created by third-party developers. If you're a developer and want to create your own extensions, see the Tableau Extensions API documentation(Link opens in a new window) on GitHub.
Before adding a Network-enabled extension or viewing a dashboard with one, be certain that you trust the website that hosts it. By default, dashboard extensions use the HTTPS protocol, which guarantees an encrypted channel for sending and receiving data, and ensures some privacy and security.
Dashboard extensions interact with data using the Tableau Extensions API library, a JavaScript library. If you want to use extensions, be sure that JavaScript is enabled in the dashboard security settings:
You can add extensions to workbooks you publish from Tableau Desktop or directly in the web-authoring mode of Tableau Cloud and Tableau Server. A Tableau administrator must allow extensions to run on a site and add Network-enabled extensions to a safe list. Administrators should only allow extensions that you have tested and trust.
The Tableau Dashboard Extensions API allows developers to create extensions for Tableau. Tableau extensions are web applications that can interact and communicate with Tableau. A dashboard extension can be placed in the dashboard like any other dashboard object.
This section will take you through the process of setting up your environment to use one of the sample dashboard extensions. Using one of the sample extensions is a great way to learn and great way to get started developing your own extensions. In this section, you will start a simple web server on your computer to host the sample. You can use the same process for hosting the extension when you start developing your own.
Note If you are looking for information about how to add an extension to a dashboard in Tableau, see Use Dashboard Extensions. If you are looking for extensions that you can use, see the Tableau Exchange.
To run extensions on Tableau Server or Tableau Cloud, support for extensions must be enabled, and depending upon the extension and the data access it requires, the extension might need to be added to the safe list for the site. See Manage Dashboard Extensions on Tableau Server or Manage Dashboard Extensions on Tableau Cloud for more information.
To use the dashboard extension samples, you need to start up a web server on your computer to host the HTML pages. If you downloaded or cloned the Extensions API repository, you can start the web service in the root directory of the repository on your computer. For example, if you downloaded the extensions-api-main.zip file to your Downloads directory, after you extract the files, the path might be Downloads\extensions-api-main\extensions-api\.
Start developing your extension by modifying an existing sample. See samples (GitHub). If you cloned or downloaded the repository, create a copy of the Samples directory. For example, if you make the copy in \extensions-api\ directory, and call it MySamples, you just need to modify the URL in the .trex files so that you host the extensions using the same web server you created with npm start command.
You need to copy them there, a prompt on how to do this should appear in the menu, if it works correctly. Just to test if something goes wrong when only installing the HYPER extensions, can you try installing all four plug-ins?
To use Tableau Extensions, Tableau has developed a functionality called the Extensions API. This functionality is the core of extensions. With it, you can receive all kinds of information from your dashboard or data source. For example, you can ask the dashboard which sheets are active, how many marks a sheet contains, which filters are used, and much more! You can also use the Extensions API to push action or information to the dashboard. Update a parameter, change the filter or refresh the dashboard every 5 seconds.
Since Tableau Dashboard Extensions are small web applications, the extensions must be hosted somewhere, just like any website. You can use Tableau Dashboard Extensions with a .trex file. This file has information about the extension, such as the name and the location of the extensions. Infotopics Apps for Tableau has an Enterprise Cloud solution, where we are hosting extensions for you. The only thing you need is the .trex file and internet access!
Currently trying to display my shiny app on tableau with the shinytableau extension. The documentation seems very sparse on the topic and I was wondering if there are any references on creating a sandboxed extension for tableau rather than the standard network based one.
Posit Connect can be used to host Tableau Analytics Extensions built in both Python and R. Python extensions are built using the fastapitableau Python package, and R extensions are built using the plumbertableau R package. Both of these packages integrate seamlessly with Connect. You can host any number of Tableau Analytics Extensions on Connect, and Connect will ensure that requests from Tableau are passed to the correct extension.
Due to how Tableau handles configuring analytics extensions, Connect must be configured on the root path of its domain (i.e.. posit.mycompany.com). You cannot configure Connect as an analytics extension if it is hosted at a domain like posit.mycompany.com/posit-connect without making additional changes to the proxy running in front of Connect.
While custom URLs are best practice for Tableau Analytics extensions, they are not required. You can access extensions published to Connect by their content identifier or vanity URL. If an extension has a vanity URL, Connect will prefer that in all of the documentation it generates.
The approach suggested here allows specific endpoints to be called, rather than requiring the Tableau user to write and submit R code in a plain text field from Tableau. This allows Tableau users to be seperate from the extension developers. R developers can build extensions that are then used by Tableau developers who may have no working knowledge of
plumbertableau automatically generates the /info endpoint and reroutes requests to /evaluate to the endpoint defined in the script value of the request body. This allows multiple endpoints to function as extensions, rather than relying on a single extension operating under /evaluate. These features are intended to allow the R developer to easily create Tableau Analytics Extensions as standard Plumber APIs without needing to worry about the lower level implementation.
