import { app, HttpRequest, HttpResponseInit, InvocationContext } from "@azure/functions" ; import { Redis } from "@upstash/redis" ; const redis = new Redis ( { url: process. env. UPSTASH_REDIS_REST_URL ,
token: process. env. UPSTASH_REDIS_REST_TOKEN
} ) ; export async function CounterFunction ( request: HttpRequest, context: InvocationContext) : Promise < HttpResponseInit> { const count = await redis. incr ( "counter" ) ;
return { status: 200 , body: ` Counter: ${ count} ` } ;
} ; app. http ( 'CounterFunction' , {
methods: [ 'GET' , 'POST' ] ,
authLevel: 'anonymous' ,
handler: CounterFunction
} ) ; Create Azure Resources You can use the command below to find the name of a region near you.

Create a storage account.
az storage account create --name < STORAGE_NAME> --location < REGION> --resource-group AzureFunctionsQuickstart-rg --sku Standard_LRS --allow-blob-public-access false
Create your Function App.
az functionapp create --resource-group AzureFunctionsQuickstart-rg --consumption-plan-location < REGION> --runtime node --runtime-version 18 --functions-version 4 --name < APP_NAME> --storage-account < STORAGE_NAME>
Database Setup Create a Redis database using Upstash Console or Upstash CLI and set UPSTASH_REDIS_REST_URL and UPSTASH_REDIS_REST_TOKEN in your Function App’s settings.
az functionapp config appsettings set --name < APP_NAME> --resource-group AzureFunctionsQuickstart-rg --settings UPSTASH_REDIS_REST_URL = < YOUR_URL> UPSTASH_REDIS_REST_TOKEN = < YOUR_TOKEN>
