Superset Embedded SDK

The Embedded SDK allows you to embed dashboards from Superset into your own app, using your app's authentication.

Embedding is done by inserting an iframe, containing a Superset page, into the host application.

Prerequisites

• Activate the feature flag EMBEDDED_SUPERSET
• Set a strong password in configuration variable GUEST_TOKEN_JWT_SECRET (see configuration file config.py). Be aware that its default value must be changed in production.

Embedding a Dashboard

Using npm:

npm install --save @superset-ui/embedded-sdk

import { embedDashboard } from "@superset-ui/embedded-sdk";

embedDashboard({
  id: "abc123", // given by the Superset embedding UI
  supersetDomain: "https://superset.example.com",
  mountPoint: document.getElementById("my-superset-container"), // any html element that can contain an iframe
  fetchGuestToken: () => fetchGuestTokenFromBackend(),
  dashboardUiConfig: { // dashboard UI config: hideTitle, hideTab, hideChartControls, filters.visible, filters.expanded (optional), urlParams (optional)
      hideTitle: true,
      filters: {
          expanded: true,
      },
      urlParams: {
          foo: 'value1',
          bar: 'value2',
          // ...
      }
  },
    // optional additional iframe sandbox attributes
  iframeSandboxExtras: ['allow-top-navigation', 'allow-popups-to-escape-sandbox']
});

You can also load the Embedded SDK from a CDN. The SDK will be available as supersetEmbeddedSdk globally:

<script src="https://unpkg.com/@superset-ui/embedded-sdk"></script>

<script>
  supersetEmbeddedSdk.embedDashboard({
    // ... here you supply the same parameters as in the example above
  });
</script>

Authentication/Authorization with Guest Tokens

Embedded resources use a special auth token called a Guest Token to grant Superset access to your users, without requiring your users to log in to Superset directly. Your backend must create a Guest Token by requesting Superset's POST /security/guest_token endpoint, and pass that guest token to your frontend.

The Embedding SDK takes the guest token and use it to embed a dashboard.

Creating a Guest Token

From the backend, http POST to /security/guest_token with some parameters to define what the guest token will grant access to. Guest tokens can have Row Level Security rules which filter data for the user carrying the token.

The agent making the POST request must be authenticated with the can_grant_guest_token permission.

Within your app, using the Guest Token will then allow authentication to your Superset instance via creating an Anonymous user object. This guest anonymous user will default to the public role as per this setting GUEST_ROLE_NAME = "Public".

The user parameters in the example below are optional and are provided as a means of passing user attributes that may be accessed in jinja templates inside your charts.

Example POST /security/guest_token payload:

{
  "user": {
    "username": "stan_lee",
    "first_name": "Stan",
    "last_name": "Lee"
  },
  "resources": [{
    "type": "dashboard",
    "id": "abc123"
  }],
  "rls": [
    { "clause": "publisher = 'Nintendo'" }
  ]
}

Alternatively, a guest token can be created directly in your app with a json like the following, and then signed with the secret set in configuration variable GUEST_TOKEN_JWT_SECRET (see configuration file config.py)

{
  "user": {
    "username": "[email protected]",
    "first_name": "embedded",
    "last_name": "embedded"
  },
  "resources": [
    {
      "type": "dashboard",
      "id": "d73e7841-9342-4afd-8e29-b4a416a2498c"
    }
  ],
  "rls_rules": [],
  "iat": 1730883214,
  "exp": 1732956814,
  "aud": "superset",
  "type": "guest"
}

Sandbox iframe

The Embedded SDK creates an iframe with sandbox mode by default which applies certain restrictions to the iframe's content. To pass additional sandbox attributes you can use iframeSandboxExtras:

  // optional additional iframe sandbox attributes
  iframeSandboxExtras: ['allow-top-navigation', 'allow-popups-to-escape-sandbox']
