Open-Source GraphQL CDN/Edge Cache with Cloudflare, Fastly, and Fly.io

What it does

Proprietary GraphQL CDNs like Akamai and GraphCDN/Stellate build a "smart" cache that reads your operations to decide what to cache and invalidate. That creates a second source of truth, ties you to one vendor, and only works when 100% of your traffic flows through it. The Cosmo Router takes the opposite, standards-based approach: with Automatic Persisted Queries, operations are addressed by a hash and served over HTTP GET, so each becomes a plain, cacheable URL. The Router's Cache-Control policy sets a max-age you control per graph or per subgraph (the strictest policy wins, and mutations and errored responses are set to no-cache), so any CDN or cache server like Cloudflare, Fastly,…from wundergraph.com

  Cozo – new Graph DB with Datalog, embedded like SQLite2022 · github.com · ▲425

  Hi HN, I have been making this Cozo database since half a year ago, and now it is ready for public release. My initial motivation is that I want a graph database. Lightweight and easy to use, like SQLite. Powerful and performant, like Postgres. I found none of the existing solutions good enough. Deciding to roll my own, I need to choose a query language. I am familiar with Cypher but consider it not much of an improvement over CTE in SQL (Cypher is sometimes notationally more convenient, but not more expressive). I like Gremlin but would prefer something more declarative. Experimentations…

  Talanoa▲346

  Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…

  A friend and I spent 6 years making a simulation game, finally released▲1,157

  I've seen some interests in (simulation) video games here on HN so I thought I'd share a short version of our story. More than 6 years ago, me and my friend from university were playing around with an idea of making a game we always wanted to play. We worked on it on weekends but the progress was quite slow, especially due to so many dead ends and wasted effort. Eventually however, we solidified our direction and decided to take the risk to resign from our well paid SWE jobs and work on it full time. It took more than a year but yesterday we have finally released it on Steam:…
