New in Astrobook: resizable sidebar, collapse toggle, and instant search. A lightweight Storybook alternative for React, Vue, Svelte, Solid, Preact, Lit & Astro.

Spider monkeys won’t suffer from floating-point rounding errors.

JSX was hated at first. Now everyone uses it. I bet directive like "use server" and "use no memo" will go through the same cycle: confusion, criticism, then acceptance.

I finally feel my M2 MacBook slowing down when I have multiple code agents running together

Exciting update for ProseKit — now you can install full editor examples directly with the shadcn CLI! Works with @react.dev @vuejs.org @preactjs.com @svelte.dev and @solidjs.com

Introducing shiki-twoslash-renderer Hover over any TypeScript code in your website to see exactly what's happening. Types, errors, insights - all there when you need them. Powered by web components, use in any UI framework.

In the next version of ProseKit, you can jump directly to the ProseKit source TypeScript code from your IDE (no more .d.ts declarations). This makes it super easy to inspect what's happening under the hood and copy & paste useful snippets.

Been working on drag & drop UX in ProseKit, especially for tricky spots like lists & tables. Feels so much better.

Lovely animation from GitHub's new review page ｡◕‿◕｡

Cursor just shipped a new design for the command palette and activity bar. It looks nice! ⬅️ VS Code - Cursor ➡️

Just added a new example showing how to customize task list checkboxes in ProseKit ✅

Congrats to the Oxlint team on the v1.0 release! 🎉 It's blazing fast, but sadly we'll have to stick with ESLint for a bit longer as Oxlint doesn't support type-aware rules

Just built a CRDT-powered real-time demo with ProseKit + @jazz.tools ⚡️ Multiple editors, synced live — no backend needed.

Surprise to know that "local-first" sync engine @rocicorp.dev Zero doesn't support offline writes.

The new version of ProseKit is now compatible with the React compiler. Reading external systems (like navigator.online) directly during the rendering phase violates React's rules. This actually makes a lot of sense to me. 🤔

tsdown builds 2x faster than tsup 🤯. Absolutely amazing! Huge shoutout to @sxzz.dev 🙌

TIL: In browser, fetch() will hide any custom HTTP response header unless you have the Access-Control-Expose-Headers header in your response.

I'm migrating a website from VitePress to Astro, and the build time has dropped from 4m22s to 1m33s. It's 2x faster 🤯

A big refactor of ProseKit’s block handle is about to land! The positioning logic is going to be much better.

It's 2025 and universities are still teaching SVN🫠

I gave VSCode and GitHub Copilot another chance today, and I immediately decided to stick with Cursor. Seeing how Cursor completed the same task in half the time compared to GitHub Copilot.

下周回国一段时间，又要学习科学的上网姿势了。这次除了把我的 v2fly 服务重新搭起来，也想试试 cloudflare zero trust。除此之外还有其他好用的技术栈吗？

I’ve been working on a project with OpenCV.js recently. It's powerful, but existing npm packages have some quirks. They requires wired initialization steps, and require extra config for bundlers like Webpack.

🚀 Loving the new Raycast Notes! Thrilled that my prosemirror-flat-list library is part of the magic behind it. Check it out! github.com/ocavue/prose...

Another node.js package manager 👀

Notion's editor is so great. I can always find some well thought little details from it. For example, the floating toolbar won't shift after applying styles. The video shows the comparison between Notion, Craft and AFFiNE:
