    Socket – Secure your JavaScript supply chain▲133

    Excited to share the project I've been working on for the past 7 months! We've seen nearly weekly attacks against the open source software supply chain. I saw the seeds of this trend start in the mid 2015s as an open source maintainer and I've watched it only get worse over the years. I finally decided to try to solve this problem.

    QuickBEAM – run JavaScript as supervised Erlang/OTP processes▲113

    QuickBEAM is a JavaScript runtime embedded inside the Erlang/OTP VM. If you’re building a full-stack app, JavaScript tends to leak in anyway — frontend, SSR, or third-party code. QuickBEAM runs that JavaScript inside OTP supervision trees. Each runtime is a process with a `Beam` global that can: - call Elixir code - send/receive messages - spawn and monitor processes - inspect runtime/system state It also provides browser-style APIs backed by OTP/native primitives (fetch, WebSocket, Worker, BroadcastChannel, localStorage, native DOM, etc.). This makes it usable for: - SSR…
