 # Deploy a Node.js + MongoDB web app to Azure
 
-In this tutorial, you'll deploy a sample **Express.js** app using a **MongoDB** database to Azure. The Express.js app will be hosted in Azure App Service which supports hosting Node.js apps in both Linux (Node versions 12, 14, and 16) and Windows (versions 12 and 14) server environments. The MongoDB database will be hosted in Azure Cosmos DB, a cloud native database offering a [100% MongoDB compatible API](../cosmos-db/mongodb/mongodb-introduction.md).

 Azure App Service is used to host the Express.js web app. When setting up the App Service for the application, you'll specify:
 
-* The **Name** for the web app. This name is used as part of the DNS name for your webapp in the form of `https://<app-name>.azurewebsites.net`.
-* The **Runtime** for the app. This is where you select the version of Node to use for your app.

 ## 3 - Connect your App Service to your Cosmos DB
 
-To connect to your Cosmos DB database, you need to provide the connection string for the database to your application. This is done in the sample application by reading the `DATABASE_URL` environment variable. When running locally, the sample application uses the [dotenv package](https://www.npmjs.com/package/dotenv) to read the connection string value from the `.env` file.

-When running in Azure, configuration values like connection strings can be stored in the *application settings* of the App Service hosting the web app. These values are then made available to your application as environment variables during runtime. In this way, the application uses the connection string from `process.env` the same way whether being run locally or in Azure. Further, this eliminates the need to manage and deploy environment specific config files with your application.
