Built a Lightning Web Component extension to the Salesforce Opportunity module which communicated info back to one of our internal applications via Azure Functions. I have to say it was one of the more interesting projects I’ve done. Definitely non-trivial. Learning Web Component creation was new, as was Azure Functions. Deploying into production was a beast. Had to remember all the CORS settings (lol).
Salesforce does development right. They have great docs and the ability to spin up dev sandbox is incredible. I’ve never seen anything like it. I did all my development for SF in Visual Studio Code.
Microsoft similarly made it easy to create and test Azure Functions in multiple languages (I chose C#). Figuring out the ins-an-outs of configuring all these pieces was easily as much work as writing all the code.
