- c# – can host freely on appharbor.com but a custom domain costs $10 a month. It would be easiest to code in c# since i’ve done similar things before and my dev environment is already running. Maybe I could just add a cname or rewrite to the appharbor sub domain instead of paying for the custom domain.
- python – can host freely on google app engine, but a custom domain requires setting up google apps account for it. Free, but complicates things. Python is an excellent language and easy to learn, but not ideal for me since I can’t use it at the office and it’s not often called for when doing contracts.
- node.js – can host freely on heroku, and custom domains are free too. but runs version 4.7 by default. upping it to 6.2 could be a pain, judging from this post by Pat Patterson. I have zero experience with node, but I’m very interested in it. it will have far fewer libraries for it since it’s so new, but I may have already found one for authentication.
I decided on node and got the current version of the my app migrated into it in about an hour thanks to express and jade. Luckily, I just found out that Heroku now supports many versions of node and npm, up to the latest. You just need to specify the node version you want in package.json.
I tried to get it working initially with iisnode and WebMatrix. But I wasn’t able to figure out how to get express working with it. Come to find out, it’s actually an open bug. iisnode is more than I need anyway for this simple app.
