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.
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'" }
]
}
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']
