We use PureScript at Awake Security (now part of Arista Networks). The language is such a joy to use for a complex single-page application. All-in we have ~150,000 lines of PureScript, though we use it for more than just the SPA (we parse protobuf files and code-generate all our APIs, among other things). We're using the bare-bones react bindings with React Hooks.

PureScript is niche, but when it's the right fit for your problem it's a wonderful language to work in and especially to maintain.

The PureScript team has launched the language's first annual survey! As with the other language surveys that come and go on Hacker News, these surveys are invaluable for teams like ours to improve the language and the ecosystem around it.

Even if you have never written PureScript, we want to hear from you! There's a (very) short section specifically for non-users.

Thanks for your time and we look forward to hearing your thoughts!
