Remix has quite the back story. Created by the duo behind React Router in 2020 and seen as an alternative to Next.js, Remix was acquired by Shopify in 2022 and its core ideas folded into React Router v7 in 2024. Now, a new direction: a full-stack, web standards-first framework with its own UI component model and… no React.

At ten years old, the ‘animate anything from JavaScript’ library continues to get even better with a new scrambleText effect and auto-grid layout mode for stagger grids. The docs for Anime are truly top-tier and packed with examples.

Another mammoth Bun release. Bun.Image is a new built-in image processing API which can replace Sharp in many cases. Bun’s package manager has added a global virtual store (akin to pnpm’s), Bun.serve has experimental HTTP/3 over QUIC support, and fetch gets HTTP/2 and HTTP/3 support. Plus the usual raft of Node.js compatibility improvements.
