Show HN: Wasp – the first full-stack framework powered by an LLM
(wasp.sh)
For those of you who are new here, we have been building a full-stack, batteries-included web framework for the last four years. You can think of Wasp as a modern, JS-based incarnation of Laravel, Django or Ruby on Rails. We based it on a custom compiler so it doesn’t depend on the specific stack or the architecture in the long run (currently it supports React, Node.js and Prisma).

V8: From CFG to Sea of Nodes and back again
(v8.dev)
V8’s end-tier optimizing compiler, Turbofan, is famously one of the few large-scale production compilers to use Sea of Nodes (SoN). However, since almost 3 years ago, we’ve started to get rid of Sea of Nodes and fall back to a more traditional Control-Flow Graph (CFG) Intermediate Representation (IR), which we named Turboshaft.

Bulletproof Sessions: Secure Session Handling Without Cookies
(tudorconstantin.com)
As if there weren't enough session handling mechanisms (session id's in each URL, cookies, http only cookies, JWT tokens in the request header), let me introduce you a novel one: having a service worker that intercepts and cryptographically signs all the requests to the origin.

Writing a tiny undo/redo stack in JavaScript
(julik.nl)
I’ve needed this before - a couple of times. Third time I figured I needed something small, nimble - yet complete. And - at the same time - wondering about how to do it in a very simple manner. I think it worked out great, so let’s dig in.

Move on to ESM-Only

Three years ago, I wrote a post about shipping ESM & CJS in a single package, advocating for dual CJS/ESM formats to ease user migration and trying to make the best of both worlds.

Why Go?
(github.com/microsoft)
Language choice is always a hot topic! We extensively evaluated many language options, both recently and in prior investigations. We also considered hybrid approaches where certain components could be written in a native language, while keeping core typechecking algorithms in JavaScript. We wrote multiple prototypes experimenting with different data representations in different languages, and did deep investigations into the approaches used by existing native TypeScript parsers like swc, oxc, and esbuild.
