Host Data API builder in Azure Static Web Apps (preview)

• An Azure account with an active subscription. Create an account for free.

• Azure Static Web Apps CLI. Install the Static Web Apps (SWA) CLI.

• Data API builder CLI. Install the Data API builder (DAB) CLI.

• Existing supported database addressable from Azure.

• Existing web application in a GitHub repository that can be deployed to Azure Static Web Apps. - If you don't have a web application, generate a repository with a basic web application.

To start, use the Azure portal to create a new Azure Static Web App using the web application in GitHub.

1. Sign into the Azure portal (https://portal.azure.com).

2. Create a new resource group. You will use this resource group to for all new resources in this guide.

   

   Tip

   We recommend naming the resource group msdocs-dab-swa. All screenshots in this guide use this name.

3. Create an Azure Static Web App. Use these settings to configure the static web app.

   Setting	Value
   Resource group	Select the resource group you created earlier
   Name	Enter a globally unique name
   Plan type	Select the best option for your workload
   Source	Select GitHub
   GitHub account	Configure a GitHub account that has access to the web application repository
   Organization	Select the parent organization or user for the repository
   Repository	Select the repository name
   Branch	Select the primary branch

   

4. Wait for the static web application deployment to complete. A GitHub Actions workflow is automatically added to your repository that will deploy the application to Azure Static Web Apps every time you push to the primary branch.

   Note

   This initial deployment can take a few minutes. You can always check the status of the deployment in either the Azure portal or the GitHub Actions tab in your repository.

5. Navigate to the new static web app in the Azure portal.

6. In the Essentials section, use the URL hyperlink to navigate to the running web application. Verify that the application is running as expected.

Now, use the DAB and SWA command-line interfaces to create a new DAB configuration file and add it to the web application repository.

1. Open the GitHub repository for your web application in the integrated developer environment (IDE) of your choice.

   Tip

   You can use any IDE you'd like. If you want to work on the application locally, you can clone the repository to your local machine. If you prefer to work in the browser, you can use GitHub Codespaces. Ensure that the SWA and DAB CLIs is installed in your development environment.

2. Open a terminal in the root of the repository.

3. Use the swa db command from the SWA CLI to initialize a new DAB configuration file using the specified database type. The command will create a new file named staticwebapp.database.config.json in the swa-db-connections folder.

   swa db init --database-type "<database-type>"
   

   Important

   Some database types will require additional configuration settings on initialization.

4. Use the dab add command to add at least one database entity to the configuration. Configure each entity to allow all permissions for anonymous users. Repeat dab add as many times as you like for your entities.

   dab add "<entity-name>" --source "<schema>.<table>" --permissions "anonymous:*" --config "swa-db-connections/staticwebapp.database.config.json"
   

5. Open and review the contents of the swa-db-connections/staticwebapp.database.config.json file.

6. Commit your changes to the repository and push them to the primary branch. This will automatically trigger a new deployment of the web application. Wait for this latest deployment to finish before continuing with this guide.

Next, configure the database connection in the Azure portal to allow the static web app to access the database.

1. Navigate to the static web app again in the Azure portal.

2. Select the Database connection option in the Settings section of the resource menu. Then, select Link existing database for the production environment.

   

3. In the Link database dialog, use these settings to configure the database connection.

   Setting	Value
   Database type	Select the same database type you used when creating the DAB configuration file
   Resource group	Select the resource group you created earlier in this guide
   Resource name	Select the database resource you want to link to the static web app
   Database name	Enter the name of the database
   Authentication type	Select the type of authentication you intend to use

   

   Tip

   We recommend using a connection string that does not include authorization keys. Instead, use managed identities and role-based access control to manage access between your database and host. For more information, see Azure services that use managed identities.

Finally, validate that the data API endpoint is available on the static web app.

1. Navigate to the static web app again in the Azure portal.

2. Use the URL field in the Essentials section to browse to the static web app's website again.

3. Navigate to the /data-api path for the current running application. Observe that the response still indicates that the DAB container is healthy.

   Healthy
   

4. Navigate to the /data-api/rest/<entity-name> path for the current running application. This issues a HTTP GET request for that set of entities. Observe the JSON response.

When you no longer need the sample application or resources, remove the corresponding deployment and all resources.

1. Navigate to the resource group using the Azure portal.

2. In the command bar, select Delete.
