Did a proof-of-concept for an Azure Function in node.js that uses Redis Cache for session storage as the function runtime is 100% managed and using memory store doesn’t make sense. Once I had this I wanted to play with the local development support but that didn’t work as I was using node.js v. 13 and the Azure tooling only works an LTS version of node.js (meaning 12.x at the time of this writing). To fix I had to uninstall my current version of node.js and switch to v. 12.x as follows (I’m using Homebrew to manage dependencies):
brew uninstall node brew install node@12
Then I had to update my PATH as the node binary is not in /usr/local/bin anymore but rather in /usr/local/opt/node@12/bin. Once that was done the Azure tooling for local application development worked like a charm.
