Quickstart: Build a Table API app with Node.js and Azure Cosmos DB

This quickstart shows how to use Node.js and the Azure Cosmos DB Table API to build an app by cloning an example from GitHub. This quickstart also shows you how to create an Azure Cosmos DB account and how to use Data Explorer to create tables and entities in the web-based Azure portal.

Azure Cosmos DB is Microsoft’s globally distributed multi-model database service. You can quickly create and query document, key/value, wide-column, and graph databases, all of which benefit from the global distribution and horizontal scale capabilities at the core of Azure Cosmos DB.

Prerequisites

[!INCLUDE quickstarts-free-trial-note] [!INCLUDE cosmos-db-emulator-docdb-api]

In addition:

Create a database account

Important

You need to create a new Table API account to work with the generally available Table API SDKs. Table API accounts created during preview are not supported by the generally available SDKs.

[!INCLUDE cosmos-db-create-dbaccount-table]

Add a table

[!INCLUDE cosmos-db-create-table]

Add sample data

You can now add data to your new table using Data Explorer.

  1. In Data Explorer, expand sample-table, click Entities, and then click Add Entity.

    Create new entities in Data Explorer in the Azure portal

  2. Now add data to the PartitionKey value box and RowKey value boxes, and click Add Entity.

    Set the Partition Key and Row Key for a new entity

    You can now add more entities to your table, edit your entities, or query your data in Data Explorer. Data Explorer is also where you can scale your throughput and add stored procedures, user defined functions, and triggers to your table.

Clone the sample application

Now let's clone a Table app from github, set the connection string, and run it. You'll see how easy it is to work with data programmatically.

  1. Open a git terminal window, such as git bash, and use the cd command to change to a folder to install the sample app.

    cd "C:\git-samples"

  2. Run the following command to clone the sample repository. This command creates a copy of the sample app on your computer.

    git clone https://github.com/Azure-Samples/storage-table-node-getting-started.git

Update your connection string

Now go back to the Azure portal to get your connection string information and copy it into the app. This enables your app to communicate with your hosted database.

  1. In the Azure portal, click Connection String.

    View and copy the required connection string information from the in the Connection String pane

  2. Copy the PRIMARY CONNECTION STRING using the copy button on the right-side.

  3. Open the app.config file, and paste the value into the connectionString on line three.

    [!IMPORTANT] If your Endpoint uses documents.azure.com, that means you have a preview account, and you need to create a new Table API account to work with the generally available Table API SDK.

  4. Save the app.config file.

You've now updated your app with all the info it needs to communicate with Azure Cosmos DB.

Run the app

  1. In the git terminal window, cd to the storage-table-java-getting-started folder.

    cd "C:\git-samples\storage-table-node-getting-started"

  2. Run the following command to install the [azure], [node-uuid], [nconf] and [async] modules locally as well as to save an entry for them to the package.json file

    npm install azure-storage node-uuid async nconf --save

  3. In the git terminal window, run the following commands to run start the Node application.

    node ./tableSample.js

    The console window displays the table data being added to the new table database in Azure Cosmos DB.

    You can now go back to Data Explorer and see query, modify, and work with this new data.

Next steps

In this quickstart, you've learned how to create an Azure Cosmos DB account, create a table using the Data Explorer, and run an app. Now you can query your data using the Table API.
