There’s no acknowledgment of Node.js trademark on Deno.com … and the landing page is largely about how much better Deno is over Node.js.
Of all places to put trademark acknowledgement, it’d be there - and it’s missing.

Project mention: Show HN: A tool to visualise Zod validation errors | news.ycombinator.com | 2024-10-01
I love it!
Zod is such a great tool but its errors can be a bit hard to parse.
Reminds me a lot of https://github.com/yoavbls/pretty-ts-errors
Disclaimer: I work with OP

I would highly recommend giving Deno Fresh[1] a go, it has a lot of the same features as Next.js but I find it to result in a much cleaner codebase overall. This coupled with Deno's built in KV store and hosted on Deploy makes for quite a zen workflow to be honest.

graphql-yoga
🧘 Rewrite of a fully-featured GraphQL Server with focus on easy setup, performance & great developer experience. The core of Yoga implements WHATWG Fetch API and can run/deploy on any JS environment.
Project mention: Show HN: Dumbo – Hono inspired framework for PHP | news.ycombinator.com | 2024-11-17You're talking about the implementation of the protocol, right?
That is a good implementation of it, called GraphQL Yoga[0]
However I'm concerned there is a slight disconnect here. I'm saying that the technical specification of GraphQL does not lend itself to being bad, rather its the failure of developers to really understand its purpose and what its for (its a giant aggregator, with various ways to optimally aggregate things together, depending on what is optimal for a given problem set)
For that, I recommend becoming more familiar with the specification itself[1] because thats what I'm talking about. The specification (and thus its technical nature) doesn't prescribe anything regarding how you get data on to the graph. Many people equate GraphQL with database problems[2]
This doesn't mean I don't understand that GraphQL has shortcomings, but all approaches to APIs have short comings. I have found GraphQL has the least amount

[2]: Common complaint I see all the time. I find it stems from a failure to understand how the entirety of GraphQL is meant to work, and some of the mechanics within. Like when to appropriately leverage DataLoader[3], for instance.

Project mention: How to Implement Translations in a React App Using TypeScript? | dev.to | 2025-05-13
The first step to implementing translations in a React app is to choose an appropriate library. One of the most popular libraries in the React ecosystem is i18next, which provides powerful features for internationalization. It allows you to easily manage translations, plural forms, and formatting.
