# 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:
|
||
|
|
||
|
```sh
|
||
|
npm install --save @superset-ui/embedded-sdk
|
||
|
```
|
||
|
|
||
|
```js
|
||
|
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(),
|
||
|
});
|
||
|
```
|
||
|
|
||
|
You can also load the Embedded SDK from a CDN. The SDK will be available as `supersetEmbeddedSdk` globally:
|
||
|
|
||
|
```html
|
||
|
<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.
|
||
|
|
||
|
Example `POST /security/guest_token` payload:
|
||
|
|
||
|
```json
|
||
|
{
|
||
|
"user": {
|
||
|
"username": "stan_lee",
|
||
|
"first_name": "Stan",
|
||
|
"last_name": "Lee"
|
||
|
},
|
||
|
"resources": [{
|
||
|
"type": "dashboard",
|
||
|
"id": "abc123"
|
||
|
}],
|
||
|
"rls": [
|
||
|
{ "clause": "publisher = 'Nintendo'" }
|
||
|
]
|
||
|
}
|
||
|
```
