Deploying to Azure with Static Web Apps

Prerequisites

Before you get started, you need to have:

• An Azure account.
• A commercetools account and a Project.
• A Custom Application configured in the Merchant Center.

Configuration

In your Custom Application config, provide the Custom Application ID you got when you configured the Custom Application in the Merchant Center.

Moreover, you need to provide the production URL from your Azure project. You can keep the standard Azure Static Web Apps URL https://<project>.1.azurestaticapps.net or provide your custom domain.

{
  "env": {
    "production": {
      "applicationId": "ckvtahxl90097sys6har1e6n3",
      "url": "https://<project>.1.azurestaticapps.net"
    }
  }
}

Using environment variables

In case you want to avoid hardcoding certain values, for example the Application ID, or the Project key, you can use variable placeholders in your Custom Application config.

{
  "env": {
    "production": {
      "applicationId": "${env:APPLICATION_ID}",
      "url": "https://<project>.1.azurestaticapps.net"
    }
  }
}

Connect Azure with GitHub Actions

The easiest way to deploy to Azure is to use Static Web Apps deployment service. This service enables first-class GitHub integration.

Follow the steps in the Azure Static Web App creator to create a new project and select GitHub as the deployment source.

Configuring build settings

In the Static Web App setup process you need to configure the following things:

• Select your organization, repository and branch.
• In the Build details section select Custom as the build preset.
• Provide the following build settings:
  • App location: /
  • Output location: public

- name: Build And Deploy
  uses: Azure/static-web-apps-deploy@v1
  with:
    action: "upload"
    app_location: "/"
    api_location: ""
    output_location: "public"
  env:
    APPLICATION_ID: ${{ secrets.APPLICATION_ID }}
    CLOUD_IDENTIFIER: gcp-eu

Configuring rewrite rules

A Custom Application is a Single-Page Application that uses client-side routing. Therefore, we need to instruct Azure to rewrite all requests to serve the index.html. For this purpose, create staticwebapp.config.json file in the root directory of your project with the following content:

{
  "responseOverrides": {
    "404": {
      "rewrite": "/index.html",
      "statusCode": 200
    }
  }
}

Test your deployment

In the Merchant Center you can now follow the steps to install the Custom Application and access it in your Projects.
