<p><strong>TLDR:</strong> Bun 1.3.14 dropped with a native image API, HTTP/3 support, and a global virtual store that makes warm installs roughly 7x faster. On the tooling side, oxlint and oxfmt got a meaningful speedup by fixing how they discover config files across large directory trees. Angular v22 is experimenting with WebMCP tools that let AI models query signal-backed state directly instead of scraping the DOM. A handful of CSS features worth knowing about landed in the mix too.</p>

<h2>Bun 1.3.14 adds native image processing and HTTP/3</h2>
<p>Bun 1.3.14 is a substantial release. The headline addition is <code>Bun.Image</code>, a native image processing API the team claims outperforms sharp. Warm installs are now about 7x faster thanks to a global virtual store, and the release adds experimental HTTP/2 and HTTP/3 client support in <code>fetch()</code> alongside HTTP/3 (QUIC) in <code>Bun.serve()</code>. There’s also a rewritten <code>fs.watch()</code> backend, ~12% faster ESM loading, and 92 bug fixes including Node.js compatibility patches and memory leak fixes.</p>
<h2>oxlint and oxfmt cut large-project lint time by ~50%</h2>
<p>The Oxc team traced a significant slowdown to config file discovery: each <code>is_file()</code> call triggers a full kernel context switch, and on codebases with 50k directories that meant 150k sequential syscalls. The fix replaces individual checks with <code>readdir</code>-based traversal, which returns file types for free. They also fused the two-phase approach (config discovery then linting) into a single pass. The result is a drop from 6.1s to 2.8s on large projects.</p>
<h2>Angular v22 exposes signal state to AI models via WebMCP</h2>
<p>Angular v22 ships an experimental <code>provideWebMcpTools()</code> API that registers Angular services and computed signals as explicit tools accessible to AI models like Gemini. The idea is that instead of an AI agent scraping your DOM, it calls a typed tool that injects a service and returns structured data. The WebMCP Inspector Chrome extension lets you verify what’s registered. It’s early, but the pattern of grounding AI integrations in actual business logic rather than surface HTML is the right instinct.</p>
<h2>CSS text-box and round() are worth your attention</h2>
<p>Two CSS features got writeups today that are practically useful. The <code>text-box</code> shorthand (combining <code>text-box-trim</code> and <code>text-box-edge</code>) removes the unwanted whitespace above and below glyphs that makes precise vertical alignment such a pain. Separately, <code>round()</code> can snap fluid values from <code>clamp()</code> or container query units to predictable steps, solving the “why is this 19.7px” problem in fluid type scales and grid layouts.</p>

<h2>Also notable</h2>
<ul>
<li><strong>TypeScript enums and bundle size:</strong> Numeric enums emit an IIFE-based bidirectional map that resists tree-shaking; <code>as const</code> object patterns or string literal unions are the practical alternatives for most use cases.</li>
<li><strong>CSS per-theme color techniques:</strong> A comparison of six CSS-only approaches for light/dark theming, from <code>light-dark()</code> (cleanest for two themes) to <code>color-mix()</code> with percentage variables (more flexible for blending).</li>
<li><strong>userTourKit May 2026 release:</strong> Ships a React Testing Library integration, a Playwright bridge, jscodeshift codemods for migrating from Joyride/Shepherd/Driver.js, and a soft-gate license replacing runtime throws with a watermark badge.</li>
<li><strong>Browser compatibility shims:</strong> Firefox and Safari quietly patch behavior when visiting major sites built around Chrome quirks; Firefox exposes these at <code>about:compat</code>, which is worth a look if you care about engine diversity.</li>
<li><strong>VS Code task runner:</strong> The built-in <code>tasks.json</code> system handles compound task launching and can replace a lot of manual terminal juggling, though it remains underused.</li>
<li><strong>AEO/GEO for AI search surfaces:</strong> Getting content cited by AI Overviews and ChatGPT comes down to crawlability by search indexers (not just training crawlers), semantic HTML, structured data, and content with specific firsthand data points models can’t synthesize.</li>

Web Digest

Bun 1.3.14 lands a native image processing API (Bun.Image), HTTP/3 support in both fetch() and Bun.serve(), a global virtual store delivering ~7x faster warm installs, and ~12% faster ESM loading. The Oxc team halved lint times on large projects by replacing sequential is_file() syscalls with readdir-based traversal and fusing config discovery with linting into a single pass. Angular v22 introduces an experimental provideWebMcpTools() API that exposes signal-backed services as typed tools for AI models, avoiding DOM scraping. CSS highlights include the text-box shorthand for precise vertical glyph alignment and round() for snapping fluid values to predictable steps. Additional notes cover TypeScript enum tree-shaking pitfalls, CSS theming approaches, browser compatibility shims, and VS Code task runner tips.
