There are some people used it quite extensively for web development (both front and back-end). This year's Hong Kong Open Source Conference will feature two Haxe talks, both are web focused:
I’ve used it for web (my failed startup was in Haxe, my side projects still are mostly Haxe).
To be honest these days I mostly just use it as a “better JavaScript” because I’d prefer my backend to be NodeJS rather than PHP or Java or sone other Haxe target. But I really do prefer it to JavaScript, even with Babel and Flow and ES6 and all the things to modernise Js.
Same here. It's a "better Javascript" for me as well.
My constraints force me to use JS for what I'm building, and Haxe does a great job of insulating me from having to write and maintain a large codebase in JS.
I've mostly used it for web (mainly react applications recently), for several companies.
The haxe->js community is growing these past years, but I still think Haxe isn't getting the love it deserves (compared to TypeScript, Flow typing for react, etc.)
For sure--see the examples of FontStruct, TiVo, DAZN, Heidi, etc. in the article, along with the part just before the quick start section. :) (It's true, it does have a large gamedev following, but it's actually quite versatile.)
