Install your tools 🛠️

Make sure you have the following installed:

  • NodeJS version 18.12.1 or greater

Download and install the Atoti UI starter

  1. Login to our Artifactory.
  2. In the left bar, expand the activeui-generic-release folder. Inside that, expand the latest available release folder.
  3. Download the artifact called ""
  4. Create a new folder AtotiTutorial on your file system and unzip this artifact into it.
  5. Open a terminal and cd into AtotiUITutorial.
  6. In the terminal, run the following command:
npm install

This installs the Atoti UI starter. In particular, it downloads all the dependencies our project needs.


The first time you run it, you will encounter the following error:

An unexpected error occurred: " Not found".

This is expected: @activeviam modules are published to Artifactory, not NPM.

To fix this, run the following command where {username} and {password} must be replaced with your ActiveViam credentials:

curl -u '{username}:{password}' >> ~/.npmrc

After running this command, your .npmrc file should include the following lines:


Explore the project files

Below are some of the key files in the starter:

  • plugins.tsx which imports a number of plugins from @activeviam/activeui-sdk.

  • index.tsx where we can find a function called activate that adds these plugins into a pluginRegistry.

  • env.development.js where the URL of our server is defined for our development setup.

  • env.production.js which defines the same thing, but this time for our production build.

Start the application in development mode

In the terminal, run:

npm start

This starts the application in development mode and opens it up in a new browser tab.

Now, everytime we edit a file and refresh the browser, our changes will be taken into account.

Let's try it!

First, create a dashboard. Open the Widgets panel: on the top left menu, click on Insert -> Widgets menu or use the W shortcut. It's full of widgets!

Full Widgets Panel

Next, find the widgetPlugins array in plugins.tsx, and remove all widgets from it except for the pivot table.

const widgetPlugins = [pluginWidgetPivotTable];

After we refresh, only the pivot table remains in the widgets!

Empty Widgets Panel.

Now let's undo this change, so we can access all the widgets later in the tutorial.

Target the tutorial server

In the 2 env files, we can change the server URLs in order to target the tutorial server:

env.development.js and env.production.js

-  contentServerVersion: "6.0.0-SNAPSHOT",
- contentServerUrl: "",
- // WARNING: Changing the keys of activePivotServers will break previously saved widgets and dashboards.
- // If you must do it, then you also need to update each one's serverKey attribute on your current server.
+ contentServerVersion: "5.9",
+ contentServerUrl: "",
activePivotServers: {
- // You can connect to as many servers as needed.
- // In practice most projects only need one.
- "Ranch 6.0": {
- url: "",
- version: "6.0.0-SNAPSHOT",
- },
- "Ranch 5.11": {
- url: "",
- version: "5.11.1",
- "Ranch 5.9": {
- url: "",
- version: "5.9.4",
- },
+ "my-server": {
+ url: "",
+ version: "5.9",

Because the above changes are in the env files, we should rebuild and restart the server:

  • In many terminals the keyboard command to stop the server is Ctrl + C.
  • Then rebuild by running:
npm build
  • You can then start the server back up by running:
npm start

After making this change, if you reload while on a dashboard, you might see a warning that no dashboard was found. This is expected. Just return to the home page and continue on from there.

Build the application for production

Development mode is handy because it allows us to easily debug the application. However, it is not fit for production because the processes that allow us to debug also dramatically slow down the app.

To create an optimized production build, let's return to the terminal and run:

npm build

This creates a number of files under /build, which can then be deployed using an application server.

For example, we could copy them into the webapps folder of a Tomcat server and start it in order to serve the optimized application to our users.

Alternatively, you can run it locally from the AtotiUITutorial folder by running npx serve ./build
