building /frens Shipped the world’s first(?) realtime streaming subscription based react server renderer infra for native mobile It’s like next.js app router, but for realtime streaming live views instead of a single fire and forget server render pass dramatically pushing the state of the art forward

building /frens "Give me six hours to chop down a tree and I will spend the first four sharpening the axe.” - some guy on Twitter claiming to be quoting Abe Lincoln I’ve been doing a lot of axe sharpening lately. That tree is freaking doomed bro

crazy how much modern react code looks like the quick and dirty one file prototypes I used to make back in 2006 I miss `with` 🥺

building /frens with ai fixed a tricky regex bug by finding the errant code, describing the problem precisely to o1-mini and asking it to precisely explain the underlying design flaw in the code that makes this bug possible It first helped me understand the precise problem, skipping stateful regex cleanup edge case. Then it proposed a solution and explained why it would solve the problem. Tests passed. Shipped the fix to production. Server rendered ui so no need for an app update 😎👍 Easily would have been 4 days of work back in 2014. Now it’s 20 minutes from laptop open to solution verified in production We are living in the sci-fi future

building /frens server rendered subscription reactivity Now the server can push surgical sub-tree view mutations in response to realtime events the big difference is the inversion of control. Now the server shall be the boss, pushing arbitrary native ui changes to the client

building /frens back in 2012, FB negotiated with Apple to let us ship app updates weekly. in 2015, React Native opened the door to push over-the-air updates daily. as of 20 minutes ago, the Frens team can push some native UI updates in a few minutes (with zero restarts!). still too slow

building /frens can’t talk about it yet. past me from 7 months ago did some very careful engineering. This week I was able to ship more stuff with the same core Get the basics right and there’s an order of magnitude less work to do and less stuff that can go wrong

building /frens realtime streaming data with arbitrarily complex queries can be tricky. but… now it works better also finally got around to configuring vscode as my debugger for both backend and frontend. Got sick of debugging in chrome :P
