We just sent $100,000 to 20 open source projects ($5000 each) that the Syntax team use regularly and depend on. Thanks to all the maintainers for all your time and efforts! Thanks to @sentry.io and @opensourcepledge.com for giving us the resources to do this. blog.sentry.io/another-year...

blog.sentry.ioWe just gave a million dollars to Open Source maintainersSentry raised its Open Source budget from $750,000 to $1,000,000 this year. Here's why, and how we split it among maintainers and foundations.

Code for jev chat is available here: github.com/w3cj/jev-chat The README includes a breakdown of how this all works and includes an FAQ.

Jev is an extremely cheap and fast classifier that can replace long LLM prompts in your workflows with more deterministic answers and actions. I break down what that means, how it works and show several demos of Jev in action in my latest video. www.youtube.com/watch?v=QbYB...

We're at a point where coding without an isolation mechanism or sandbox is way too risky. Use containers at a minimum, VMs if you have enough resources or a remote machine with either of these if you can. Watch 🍿: www.youtube.com/watch?v=-ulR...

If you were building a full stack JS framework from scratch today, what would you add that is missing from Next.js, SvelteKit, Nuxt, Tanstack Start and Solid Start?

The lack of route level middleware in Next.js has always bugged me. Claude added the feature to vinext in under an hour! Unlikely to be merged in but vinext being vite based makes things like this possible! Code: github.com/w3cj/vinext/... Demo: vinext-route-proxy-examples.cj-syntax.workers.dev

github.comAdd route level proxy by w3cj · Pull Request #1 · w3cj/vinextvinext currently only supports a single top-level proxy.ts/middleware.ts that runs before all routes — the same limitation as Next.js. Users must use matcher patterns and if/else to scope logic to ...

We rebuilt Next.js in a week. No, really. The team ported the framework to run natively on Workers to prove what’s possible with edge-first architecture. Dive into the technical hurdles we solved to eliminate Node.js dependencies. https://cfl.re/3OqDpyJ

cfl.reHow we rebuilt Next.js with AI in one weekOne engineer used AI to rebuild Next.js on Vite in a week. vinext builds up to 4x faster, produces 57% smaller bundles, and deploys to Cloudflare Workers with a single command.
