Project mention: Ask HN: How would you build a turn-based multiplayer browser game in 2025? | news.ycombinator.com | 2025-04-07
I've recently been tinkering away at a turn-based multiplayer browser game in my downtime. I'm a Typescript guy so my current tech stack is Next.js, Node.js, and ws[0] for WebSockets (though I'm thinking of switching over to socket.io[1] given how much more they provide out of the box).
Right now my main concern is how to handle continuous deployments without interrupting ongoing games (amongst other WebSocket challenges[2]). I was planning to deploy via Coolify, but am considering other options given that their zero downtime deploys still needs some love[3].
How would you approach building a turn-based multiplayer browser game in 2025?

Project mention: Show HN: Triplit – Open-source syncing database that runs on server and client | news.ycombinator.com | 2024-06-25
This is just using sqlite under the hood and none of this will scale. Why build your own query builder as well when you could just hook in one of the many ORMs in the NPM ecosystem and add support for 50+ other databases. This also isn't really something you could drop into an existing project very easily. Overall, I'm not impressed.
Here are some other options I prefer:

Hey Angular developers! 🅰️ Most of the time, we find ourselves in an endless cycle of updating hard-coded content, making code changes, rebuilding our apps, and redeploying just to fix a typo or update a small description, which is not efficient because there's a smarter way to go about it. In this guide, I'll walk you through how to integrate Sanity CMS, with Angular.

Is there an official production-ready solution for getting the 'Live Query' unofficial feature working? (I'm not talking about 'subscription')
I've found some [1] [2] [3], but they're either archived or not ready for production.
I want to register from my clients (frontend app) for specific (can be complex) queries and get updates on changes.
