Implementation of Photon Realtime Webhooks Sample in Azure Functions Server-less approach. A Photon Turnbased Webhooks sample using Azure Functions, Azure Blob & TableStorage and Notification Hub.
- Photon Realtime Account
- Visual Studio Code and Azure Functions CLI for local development
- Azure Subsciption - can get �150 free Azure Credit
- Node.js & Azure Functions CLI after install open powershell and run
npm i -g azure-functions-clito install Azure Functions CLI - PostMan
Sign up for your free trial month of Microsoft Azure now and get USD 200 / EURO 150 to spend on all(!) Azure services you like to try out – without any further obligation!
You'll get the full power from the Cloud and you can choose yourself, how to spend your balance!
For authentication purposes you'll need a credit card to sign up. Without a credit card request a free Microsoft Azure Pass simply by sending a short note to azurenow@microsoft.com. Use the Microsoft Azure Pass to sign up at www.windowsazurepass.com and you'll also discover the cloud power of Microsoft Azure for free!
- Open the code using Visual Studio Code folder explorer & hit run!
- Login to Portal and go to your newly created resource group and the storage account within it
- Select the Azure Storage > Access Keys (copy paste into the config) & Azure Notification Namespace > Notification Hub > Access Keys
- set
"AzureBlob": "{your connection string here}" - set
"AzureNotificationHub": "{your connection string here}"
Deployment of the Azure Infrastructure will also update connection strings of created resources in the source code so no changes are required to get the sample running in azure;
however connection strings will be required for Storage Account & Notification Hub, these are updated in appsettings.json
Then send a POST request e.g. localhost:7071/api/hello-world/GameCreate.
In the format localhost:{port}/api/{appId}/Game{Controller}
A PostMan Collection with examples is include in the Repo
Hit this link to create all infrastructure required to run locally and in Azure.
Note - this will host the Functions in Azure as well as the infrastructure, the 1st 1M function calls in azure are free, functions are charged at a per request basics so hosting the functions will not use credit if they aren't called.
Created Infrastructure
-
Storage Accounts contain different ways to persist data in tables, queues or binary large objects (Blob). This project uses blob and table storage to store game event data
-
Azure is able to host websites and web api's in the cloud. This code will be automatically deployed to a web api app read for a Http request to be sent
-
Notification Hub Namespace and Notification Hub -
Notification Hub in Azure is like a queue, we can send a message and our client will consume that message, and respond accordingly
-
Application Insights allows us to track numerous aspects of out project, such as execution time, errors, calls and many more, this can then be linked with BI services to get deep insight into performance and such from our code
-
Azure Functions is a way to run code in azure without a dedicated server. The code base is hosted in Azure and is on a per operation price plan, meaning you only pay for what you use. 1st 1 million request per month are free! Functions allow many different triggers, a new blob in blob storage, a message on a queue, manual triggers or in our case HTTP triggers via REST
Deployment of the Azure Infrastructure will also update connection strings of created resources in the source code so no changes are required to get the sample running in azure;
however connection strings will be required for Storage Account & Notification Hub, these are updated in appsettings.json
Azure Notification Hub requires clients to be registered with the back-end service,
as well as notifications for specific client OS.
A template has been created for messages in Common/HubMessage.csx & a template for sending a message in Common/NotificationHub.csx, implement your own logic here for sending push notifications to specific clients.
Create your Photon Realtime account login and create a new app. Use the Url from your hosted Azure Functions e.g. https://photoncloud.azurewebsites.net.
Hit Manage -> Create Web Hook, set your Url and Paths for the controllers and hit apply.
Your Photon Cloud Realtime account is now pointing to your Azure Web Api
