I just reworked my previously posted code access a google photos album list to use async/await and think it gives a good account of itself. It’s not a massive change but I think easier to read and less boiler plate.
As Azure Functions only support nodejs 6.5.0, I switched to typescript in order to use async/await but I want to use it any way. More versions of node will be supported (it’s work in progresss) so you will be able to use async/await without typescript’s extra transpilation step.
