Azure Functions

26. DEMO

27. OK… That’s pretty cool, but…
• I’m a real developer…
(…I use Visual Studio and everything)
• I don’t want to write code in a ‘web browser’
(…although sometimes I do use VSCode)
• I’ve been writing code this way for ages
(…and I’m unlikely to change anytime soon)

28. So … Creating Azure Functions Locally
…(potentially) without an internet connection

29. So … Creating Azure Functions Locally
Today’s Tools:
• Visual Studio 2017 (v15.5 +above)
• ‘Azure Functions Tools’ for Visual Studio
• Azure Storage Explorer
• Azure Storage Emulator
• Postman - API Development App

30. So … Creating Azure Functions Locally
• Why / What’s Postman ?

31. So … Creating Azure Functions Locally
• Well.. Anything than can make a ‘http request’ can trigger an
Azure Function

32. So … Creating Azure Functions Locally
• So… We’ll use Postman to submit mock JSON requests

33. So… Lets create some
Local Azure Functions

34. DEMO

35. OK… That is cool, but…
• How do deploy my ‘local’ azure functions …to Azure
(…when I have an internet connection)
• I don’t want to copy/paste code in a ‘web browser’
• What about source/version control?

36. So… Lets deploy some
Azure Functions
