Let’s deploy the Function to Azure and watch it call SharePoint!

This is the second post about Azure Functions V2, with PnPJs and Visual Studio code. I decided to split this post into two. The next post will focus on using the Azure Key Vault with our JavaScript Solution.

This post is about deploying our app, and while we do that we have a look at the local vs productions variables.

An Azure Function to work with

Have a look at the first post if you want to install the prerequisites and build the function from scratch:

You could also clone it from my Github and follow the instructions (please have a look at the readme):

Deploy with VS Code and Azure Function Extensions

As I mentioned earlier there are multiple ways for us to deploy this function. In the last blogpost we utilized the VS Code extension so let’s go with that first.

  1. Press the Deploy to Function App

deploy azure app
deploy azure app

  1. Select or create a new Function App
  2. Select or create a new Resource Group
  3. Select or create a new Storage Account

Let the extension run its magic. After some time you should receive a message that the function has been deployed. Right now we don’t have any production variables, so we will use an awesome feature in the extension for this. We could also change the settings from the UI in the VS Code extension. Really smooth!

It should now work in Azure, awesome!

Deploy via Azure Function Core Tools (CLI)

We have a couple of options, here are two:

  • Create a Function App via the CLI and then publish our app
  • Create a Function App from the UI.

Just to demonstrate how to fetch the Application settings from an existing Function App, we will create a Function App from the UI.

The local.settings.json is only being used locally, our settings are never transferred to Azure.

Create Function App from the Azure Portal

If you don’t have a function app from the previous steps, create one here.

  1. Log in to the Azure Portal -> Create new resource -> search for Function App and select create.
    new app
    new app
  2. Fill in all the values and then create
  3. Wait until the app has been created

(OPTIONAL) Get Application Settings

We are going to use the Azure Functions Core Tools that we installed in the previous post, to get the application settings of our newly created app. We don’t need to get these before we deploy, I’m just showing you that you can. There might be some scenarios where you would want the storage settings etc.

  1. Open a node console and cd into our VS Code project.
  2. Run the following command to fetch all application settings and they will be pushed into the local.settings.json file.
func azure functionapp fetch-app-settings <FuncApp>

Deploy our function with local settings

So we publish our app and use the local.settings.json to overwrite the App Settings in Azure. We don’t overwrite and remove all the settings, we just add the new settings and overwrite/update if there are any with the same name.

func azure functionapp publish <FuncApp> --publish-local-settings -i --overwrite-settings -y

cli publish
cli publish

And let’s try it in the browser:

azure test
azure test

Recap

So deploying an Azure Function from Visual Studio Code is very easy, I like the Functions Extension. And I really like that we could change the Application Settings easily from the extension.

As you saw in the other example, we created a new Function App to receive the settings from Azure. You don’t have to do that, you could fetch settings from any of your Function Apps.

Another really easy way to deploy this function would be to:

  1. Create a Function App in the Azure Portal
  2. Clone my repository from GitHub
  3. Fill in the values in local.setting.json
  4. Run func azure functionapp publish <FuncApp> --publish-local-settings -i --overwrite-settings -y

And of course, we could both get the settings, and set from local settings via the Extension in VS Code.

And you would be done!

Anyways the next post will be using the Azure CLI and Azure Key Vault!
