tinyjs: Build JavaScript Desktop Apps in <10MB — I built an app with this and was impressed. You get a txiki.js-powered backend with full system access (including FFI!), native webview rendering, and tiny macOS, Linux, and Windows builds. It even makes it easy to sign/notarize the final app.

There are lots of great options in this space though:

• Electrobun offers richer multi-window and GPU features, at the cost of a larger TypeScript runtime – though it can instead use Zig, Rust, Go, or Odin for a tiny native main process.

• Perry is a TypeScript to native AOT compiler whose primary UI model renders AppKit, Win32 and GTK4 widgets for a more conventionally native feel.

• Electron and the experimental Deno Desktop are powerful, but their executables typically run several times larger.

• Neutralinojs apps can be even smaller than tinyjs's, but you lose the general-purpose JavaScript privileged backend by design.

How Linear Reworked Its CI for 4x the Tests — Eager agents grew Linear's test suite, and its CI costs with it! They share some remedies: rewriting type-aware ESLint rules as plain AST checks cut lint time 55% and eased a move to Oxlint, while selectively turning off Vitest's isolation saved a further 17% a month.

IN BRIEF:

• Lovable rewrote Vite's dev server in Rust (calling it OJ) for performance reasons, but Evan You disputes the benchmark and predicts AI will have everyone maintaining "their own slop fork".

• 📊 npmchart.com plots download trends, releases and repo activity for any npm package (here's Svelte's, for example), and lets you compare packages.

• 🔒 npm now offers stage-only tokens to let automated workflows stage a release for a maintainer to approve with 2FA. This offers a migration path for those who can't move to trusted publishing yet.

RELEASES:

• Turborepo 2.11 – Experimental Rust, Python and Go support joins the task graph, plus up to 4x faster startup over 2.9.

• ESLint 10.11.0 – Performance update with faster startup and linting.

• Node.js 26.10.0 (Current) – Adds util.debounce/throttle.

• 📊 billboard.js 4.1, QuickJS-ng 0.17.0, VueUse 15.0

Do Frameworks Matter Anymore? — If you're using AI, you're either using a framework or your agent is building an ad-hoc one on the fly. A Remix team member argues that's a good reason to want frameworks, and better ones, too.
