POC To Show Capabilities of using Azure Functions Scheduling to Notify of Reddit Posts

What is the Goal Here?

• To see ease of implementing 3rd party Packages in Azure Functions
• Stateless way of getting notified using 3rd Party Services
• Proof to see how quick a function can be stood up

What does this app do?

• Uses Azure Function Schedule Trigger (currently runs every minute using "0 */1 * * * * CRON)
• Uses RedditSharp to "scrape" Reddit subreddit (in this case /r/Azure)
• Gets Posts tht have been created within the last minute, digests them, and emails with SendGrid

Getting Started:

• Clone this Repo and restore :

  git clone https://github.com/isaac2004/RedditPoller  
  dotnet restore
  

• Configure Azure Components

  • Setup Free Azure Subscription (if you do not have one)
  • Add new instance of SendGrid (Free Version) on your subscription
    • You get 25k emails a month here
    • Capture Api Key created during process and place in host.json "SendGridApiKey" setting

• Publish App from Visual Studio 2017 Preview 3.0

  • Right-Click RedditPoller project
  • Create new Function App, Storage Account and Deploy
  • Add SendGrid Api Key and email to be notified in App Settings of Azure Function

• How can this be extended?

  • Add custom logic to notify on specific posts (matching a keyword for instance)
  • Add auth against Reddit (supported with RedditSharp) to get access to mailbox/subscribed subs/etc
  • MakeTimerTrigger customizable
  • Really options are plenty for adding hooks to Reddit
