Deploy Node.js app to Azure Functions

Git RepositoryEdit on Github

Overview of a workflow

  • Pushing a new commit to a main branch triggers a workflow.
  • Use Yarn to build a project and publish to Azure App Service with Azure/functions-action.
  • A workflow is defined by a YAML (.yml) file in the .github/workflows/ directory in your repository.
  • We use a Node.js project from a code example in Azure Functions content.

All required GitHub secrets

  • AZURE_FUNCTIONS_APP_PUBLISH_PROFILE, set to a value of publish profile content that we download from Azure portal.
  • AZURE_FUNCTIONS_APP_NAME, set to a name of Azure Functions that you are about to deploy.
