TodoMVC Backend Implementation with Azure Functions, Node and Azure SQL

Implementation of the Todo Backend API using Azure Function, Node and Azure SQL.

Unit Test

As per Todo Backend API specifications, unit test can be run via this link:

Todo Backend Specs Unit Test

Keep in mind that I'm using the free tier of Azure Functions, so the runtime will go to sleep if no-one is using it. Wake up can take up to 30 seconds, so if you run the test you may get errors like the following:

If that happens run the test couple of times and you should see all test passing.

Live Client

You can also test this implementation right using the live ToDoMVC test app:

Setup Database

Execute the /database/create.sql script on a Azure SQL database of your choice, then use SQL Server Management Studio or Azure Data Studio to run the script.

If you need any help in executing the SQL script on Azure SQL, you can find a Quickstart here: Use Azure Data Studio to connect and query Azure SQL database.

If you need to create an Azure SQL database from scratch, an Azure SQL S0 database would be more than fine to run this sample.

az sql db create -g <resource-group> -s <server-name> -n <database_+_name> --service-objective S0

Remember that if you don't have Linux environment where you can run AZ CLI you can always use the Cloud Shell. If you prefer to do everything via the portal, here's a tutorial: Create an Azure SQL Database single database.

If you are completely new to Azure SQL, no worries! Here's a full playlist that will help you: Azure SQL for beginners.

Run sample locally

Make sure you add the information needed to connect to the desired Azure SQL database in the local.settings.json. Create it in the root folder of the sample using the .template file, if there isn't one already. After editing the file should look like the following:

{
  "IsEncrypted": false,
  "Values": {
    "FUNCTIONS_WORKER_RUNTIME": "node",
    "AzureWebJobsStorage": "UseDevelopmentStorage=true",
    "db_server": "<server>.database.windows.net",
    "db_database": "<database>",
    "db_user": "todo-backend",
    "db_password": "Super_Str0ng*P@ZZword!"
  }
}

where <server> and <database> have been replaced with the correct values for your environment. Once done that, start local Azure Function host with

func start

if you are using Azure Functions Core Tools or using Visual Studio Code Azure Function extension

For more info on other options to run Azure Function locally look here:

Code and test Azure Functions locally

Once the Azure Function HTTP is up and running you'll see something like

Now listening on: http://0.0.0.0:7071
Application started. Press Ctrl+C to shut down.

Http Functions:

        todo: [GET,PUT,PATCH,DELETE] http://localhost:7071/api/todo/{id:int?}

Using a REST Client (like Insomnia, Postman or curl), you can now call your API, for example:

curl -X GET http://localhost:7071/api/todo

and you'll a list of existing todo:

[
  {
    "id": 549,
    "title": "azure function nodejs sample",
    "completed": false,
    "url": "http://localhost:7071/api/todo/549"
  }
]

Debug from Visual Studio Code

Debugging from Visual Studio Code is fully supported, thanks to the Visual Studio Code Azure Function extension

Deploy to Azure

If you want to the deploy this solution to Azure, you can take advantage of the script azure-deploy.sh that uses AZ CLI to deploy Azure Functions. It needs to be executed from a Linux shell. If you don't have one on your machine you can use Azure Cloud Shell. Just make sure you fill the needed settings into the local.settings.json as mentioned before as the script will read the values from there.

./azure-deploy.sh

It will care of everything for you:

• Creating a Resource Group (you can set the name you want by changing it directly in the .sh file)
• Creating a Storage Account
• Creating Azure Application Insights
• Create an Azure Function app
• Deploying repo code to Azure Function

Enjoy!
