Develop plugins for Sigma


Plugins are third-party applications built to add additional functionality into an existing product. Sigma supports plugins for workbooks. Developers build plugins using Sigma’s Plugin API, which communicates data and interaction events between a Sigma workbook and the plugin. Developers host these plugins, embed them in an iframe element in Sigma.

User requirements

The ability to develop and test your plugin in Sigma Plugin Dev Playground requires the following:

  • You must be assigned an account type with the Manage plugins permission enabled.
  • You must be the workbook owner or be granted Can edit workbook permission.
  • You must develop the plugin using JavaScript, and it must be designed to execute in a web browser environment.

Create a development project

At Sigma, we use the React libraries for front-end development. We recommend that you use the same environment to develop custom plugins for your organization in Sigma. If you choose to use a different method, ensure that you use JavaScript. Sigma supports both standard JavaScript API and React Hooks API.

Create a project with React

  1. Open your terminal and navigate to the directory where you plan to create your project.

  2. Create a new project.
    We recommend using Facebook’s Create React App.

    npx create-react-app <my-cool-plugin>

  3. Navigate to the project's main directory.

    cd <my-cool-plugin>

  4. Use your package manager to install Sigma’s plugin library.
    We recommend yarn.

    yarn add @sigmacomputing/plugin

  5. Spin up your local host.

    yarn && yarn start

  6. Start developing:

Plugin Development API

To view documentation for API documentation for this feature, see The plugin development playground

Plugin developers should have access to a special plugin called Sigma Plugin Dev Playground. This plugin is available from any workbook and points to http://localhost:3000, by default.

If you cannot find this plugin or would like a development playground with an alternative default host, please contact your Organization Admin with a request to Register a Plugin with its production URL set to your preferred development URL.

Use the development playground

  1. Set your plugin’s development URL to http://localhost:3000.

  2. Run your plugin remotely.

    If you followed our recommendations under Create a Development Project, enter the following command in your terminal.

    yarn && yarn start

  3. Create/open a workbook.

  4. In the workbook header, click Edit.

  5. Click the + button in the sidebar to open the workbook’s ADD NEW panel.

  6. Select the PLUGINS element type, located under UI ELEMENTS.


  7. The editor panel will show you a list of available plugins. Select Sigma Plugin Dev Playground.


    Your new plugin element appears on the page. The editor panel will only display content if you have configured your plugin using Sigma’s plugin Configuration API. Likewise, the element will only display content if your plugin is configured to display content. If you change a plugin's configuration options, input values will need to be re-added in the editor panel.

Next steps:

  • You can refresh your plugin as you make changes to its code. This option is available from the element’s menu.
  • You are responsible for hosting your plugin. When you’re ready to register your plugin, visit Register a Plugin with Sigma.

Test the plugin in development

  1. Start up your development server. If you followed our recommendations under Create a Development Project, enter the following command in your terminal:

    yarn && yarn start

  2. Create or open a workbook.

  3. If you want to work with an existing element using the plugin, select that element. Otherwise, create a new plugin-based element.

  4. Hover over the element and click the vertical ••• icon button in its top right corner.

  5. Select Point to Development URL.

  6. In the Configure Dev Server modal, enter your development URL.


  7. Click Confirm.

Next steps

  • Your Sigma plugin element will automatically update to reflect saved changes to your code. There is no need to refresh the Sigma page.
  • You can switch back to the production URL at any time, from the same element menu you used to set your temporary development URL (see steps above).

If you change a plugin's configuration options, input values will need to be re-added in the editor panel.

Host your plugin

As a plugin developer, you are responsible for hosting your plugin. If you’re new to hosting your projects, we recommend these popular hosting platforms: Heroku and Netlify.
