Serverless backend for the Gif-Collage application utilizing Azure Functions, SignalR, EventGrid, CosmosDB, and Blob Storage.

Terraform is not required, but makes setting up Azure Services seamless. NOTE: A change in the backend "remote" block in provider.tf may be required. Run the following commands once Terraform Cloud is connected.

terraform workspace new prod # or dev
terraform init
terraform apply

This will run the Terraform IaC to set-up the serverless infrastructure required to run GifCollage.

2. Fill out the necessary configurations in local.settings.json using the sample.local.settings.json file as a template.
3. Run npm install.
4. Run npm run offline command to run the azure function app locally.
5. (Optional / Required for File Uploads) Navigate to the Event-Grid System Topic in Azure Portal for the storagifcollage<env> i.e: storagegifcollageprod account. Use this page for creating the event-grid subscription for the local "gifCollageUpload" Function. The steps for setting up can be found in the following wiki provided by Azure: Here. You can use the following guide below to create the new event subscription.
   • Basic tab
     • Event Subscription Name: filesavesub-gifurl-local
     • Event Scheme: "Event Grid Scheme"
     • Filter to Event Types: "Blob Created"
     • Endpoint Type: Webhook
     • Subscriber Endpoint: <ngrok url>/runtime/webhooks/EventGrid?functionName=gifCollageUpload
   • Filters tab
     • Enable Subject Filtering
     • Subject begins with: /blobServices/default/containers/gifcollage/blobs/files/

NOTE: Every time you start ngrok, the HTTPS URL is regenerated and the value changes. Therefore you must create a new Event Subscription each time you expose your function to Azure via ngrok.
