### Copy Environment File for Local Development

Source: https://github.com/metabase/metabase-nodejs-modular-embedding-sample/blob/main/README.md

Copy the example environment file for local development and edit it with your Metabase instance URL, JWT secrets, and dashboard ID.

```bash
cp .env.example .env
# Edit .env with your Metabase instance URL, JWT secrets, and dashboard ID
```

--------------------------------

### Run E2E Tests

Source: https://github.com/metabase/metabase-nodejs-modular-embedding-sample/blob/main/README.md

To run the end-to-end tests, first start the Docker containers, then navigate to the e2e directory, install dependencies, and run the Cypress tests.

```bash
# Start Docker containers
npm run docker:up

# Run Cypress tests
cd e2e
npm install
npm run cypress:run
```

--------------------------------

### Copy Environment File for Docker

Source: https://github.com/metabase/metabase-nodejs-modular-embedding-sample/blob/main/README.md

Copy the example environment file for Docker and edit it to add your Metabase premium embedding token.

```bash
cp .env.docker.example .env.docker
# Edit .env.docker and add your MB_PREMIUM_EMBEDDING_TOKEN
```

--------------------------------

### Docker Environment Variables for Local Development

Source: https://github.com/metabase/metabase-nodejs-modular-embedding-sample/blob/main/DEV.md

Define these environment variables in your `.env.docker` file to enable local Docker testing with specific development settings.

```env
MB_RUN_MODE="dev"
METASTORE_DEV_SERVER_URL="https://token-check.staging.metabase.com"
```

--------------------------------

### Use SSO Authentication in Client

Source: https://github.com/metabase/metabase-nodejs-modular-embedding-sample/blob/main/README.md

The client-side uses SSO authentication by providing the dashboard ID and configuring Metabase with the instance URL and the JWT provider URI.

```html
<metabase-dashboard
  dashboard-id="1"
  with-title="true"
></metabase-dashboard>

<script>
  defineMetabaseConfig({
    instanceUrl: "http://localhost:3000",
    jwtProviderUri: "http://localhost:3100/auth/sso",
  });
</script>
```

--------------------------------

### Use Signed JWT in Client for Guest Embed

Source: https://github.com/metabase/metabase-nodejs-modular-embedding-sample/blob/main/README.md

The client-side uses the signed token provided by the server within the `<metabase-dashboard>` component. It also configures Metabase with guest embedding settings.

```html
<metabase-dashboard token="<signed-token>" with-title="true"></metabase-dashboard>

<script>
  defineMetabaseConfig({
    isGuest: true,
    instanceUrl: "http://localhost:3000",
  });
</script>
```

--------------------------------

### Generate Signed JWT for Guest Embed

Source: https://github.com/metabase/metabase-nodejs-modular-embedding-sample/blob/main/README.md

The server generates a signed JWT token for guest embeds. This token includes the resource ID, parameters, and an expiration timestamp.

```javascript
const payload = {
  resource: { dashboard: 1 },
  params: {},
  exp: Math.round(Date.now() / 1000) + 10 * 60,
};
const token = jwt.sign(payload, MB_EMBEDDING_SECRET_KEY);
```

--------------------------------

### Generate User JWT for SSO Embed

Source: https://github.com/metabase/metabase-nodejs-modular-embedding-sample/blob/main/README.md

The server returns a JWT at the /auth/sso endpoint for SSO embeds. This token contains user information and is signed with a shared secret.

```javascript
const ssoPayload = {
  email: "rene@example.com",
  first_name: "Rene",
  last_name: "Descartes",
  groups: ["Customer"],
  exp: Math.round(Date.now() / 1000) + 10 * 60,
};
const ssoToken = jwt.sign(ssoPayload, MB_JWT_SHARED_SECRET);
res.json({ jwt: ssoToken });
```
