Desktop Apps With deno desktop — Deno 2.9 (or the 'canary' build now) can turn JavaScript projects into self-contained apps on macOS, Windows, and Linux. Unlike Electron, you can opt to use the default OS WebView or a bundled Chromium backend, plus you get cross-compilation and automatic support for apps built on frameworks like Next.js and SvelteKit.

📉 It's not in the post, but a --compress option gets packaged app sizes down a lot – from 65MB to 19MB in my test with a basic app.

Catch Runtime Bugs Before Your JS PR Merges — Some JavaScript bugs only show up after the app runs. Greptile reviews each PR with full repo context, runs the code in a sandbox, and returns screenshots, logs, and traces as proof of what broke. Use Greptile in GitHub, GitLab, or from your terminal.

Babel 8.0 Released: The JavaScript Transpiler — It’s been eight years since Babel 7.0, and despite the rise of tools like SWC and Oxc, weekly downloads of the @babel packages have increased 380x since. v8.0 is a modernization release that goes ESM-only and targets ~ES2023 by default (vs ES5 before).

IN BRIEF:

• Cloudflare has added the ability to create and deploy Workers on 'temporary accounts'. Ostensibly 'for AI agents', but you can use them yourself too, and get a Worker running for 60 minutes with no strings attached.

• TC39 delegate Luca Casonato has made a proposal to add built-in localized time formatting to <time>, akin to GitHub's <relative-time> element.

• 🤖 MDN has introduced an official MCP server to provide better access to MDN's up-to-date JS and frontend docs to coding agents.

• The Bun team has proposed adding shared-memory threads to JavaScriptCore (a more traditional threading approach versus worker threads).

RELEASES:

• ⭐ Vite 8.1 – Adds experimental support for 'bundled dev mode' which radically speeds up dev server startup and full reloads on large apps. Also adds WASM/ESM integration support.

• ⭐ Astro 7.0 – The popular web framework gets faster build times, with .astro compilation and Markdown/MDX processing going through a Rust-powered pipeline. Advanced Routing also gives you full control over the request pipeline.

• pnpm 11.7 and 11.8 – pnpm install gets a --dry-run option, --frozen-store adds support for read-only package stores, and more.

• Node.js v26.3.1 (Current), v24.17.0 (LTS), and v22.23.0 (LTS)

How an Underrated Refactor Saved 90% Memory Usage — The tale of how TanStack Table v9 uses less memory than v8 on large tables, thanks to a simple idea: storing methods on shared prototypes instead of creating them for every object. Benchmarks included, plus a pattern other libraries can copy.

FullCalendar 7.0: A Full Sized JavaScript Calendar — A Google Calendar-style experience for your own apps. Works with React, Vue and Angular (v7.0 adds Angular 22 support), but can be used with plain JavaScript. Here’s a demo where you can play with the themes and styling approaches. MIT licensed with commercial extensions.

Prop For That: What JS Knows, Now CSS Knows — Provides CSS with access to values you'd often need JS to provide (e.g. pointer position, time, a slider’s value). Add attributes to HTML and live values show up as custom properties, bridging the JS–CSS gap. The demo page is neat.

• Nuxt UI 4.9 – The Vue UI library improves its calendar component, adds uniform focus styles, and adds useTour for driving guided tours.

• Nx 23.0 – The monorepo tool's yearly major. Now nx migrate can hand migrations off to AI agents.

• ☀️ SunCalc 2.0 – Calculate the position and phase of the Sun and Moon.

• A developer code-golfed a signal implementation to just 33 bytes (above). I had to stare at it for a solid minute before it clicked, but mercifully, a Redditor breaks down exactly what's going on.

• 🔒 GitHub has released actions/checkout v7 that "refuses common pwn request patterns by default" including refusing to fetch fork pull request code in pull_request_target and workflow_run workflows.

• If you're a GitHub project maintainer getting flooded with PRs, GitHub now has the ability to limit the number of PRs any single user can open at once.
