I’m happy to report that, earlier today, I published an early version of express-twtkpr: an ExpressJS library that enables hosting (and directly posting to) a twtxt.txt file. It works great (otherwise you wouldn’t be able to read this), but it’s still in alpha and lacks documentation, examples, tests, installation flexibility, or polish, so please use it at your own risk. Enjoy! https://www.npmjs.com/package/express-twtkpr
