<h2>Chrome 151 ships native SPA metrics, web-vitals v6 requires careful migration</h2>
<p>Chrome 151 lands stable support for soft-navigation and interaction-contentful-paint entries on the Performance Timeline — the first time SPAs can be measured natively without workarounds. The web-vitals v6 library ships alongside it with a one-second requestIdleCallback cap and improved INP reporting after bfcache restores. The catch: one document can now produce multiple metric lifecycles, which means existing dashboards risk double-counting, population shifts, and false regressions. The recommended path is a parallel run — comparing v5 and v6 side by side and reconciling percentiles before cutting over. Chrome 152 Beta also introduces a coarse CPU Performance Tier API for device segmentation. <a href="https://daily.dev/posts/Ia9s4dkOC" target="_blank" rel="noopener nofollow">Read more</a></p>
<h2>State of CSS 2026: anchor positioning is developers’ favorite feature they can’t actually use</h2>
<p>The 2026 State of CSS survey results are in, with 4,902 respondents. Anchor positioning topped both the ‘favorite new feature’ list and the ‘wish it had better browser support’ list simultaneously — which tells you everything about where CSS enthusiasm and browser reality are currently misaligned. The most-used newer features are :has(), aspect-ratio, and CSS nesting. CSS gap decorations (covered in yesterday’s digest) shipped in Chrome and Edge 149. <a href="https://daily.dev/feed-by-ids?id=SBmWLqr5Y&amp;id=95LEJbgQd" target="_blank" rel="noopener nofollow">Read more</a></p>
<h2>TanStack ships Charts pre-alpha, plus Markdown and Highlight libraries that cut 1.1 MiB to 27 KiB</h2>
<p>TanStack Charts 0.3.1 is a typed, tree-shakable charting library built on a grammar-of-graphics approach — the framework-neutral scene weighs 8.12 KiB gzip. Separately, TanStack Markdown and TanStack Highlight are in alpha, built to replace a bloated pipeline on <a href="http://tanstack.com" target="_blank" rel="noopener nofollow">tanstack.com</a> that was transferring over 1.1 MiB of script per docs page (358 KiB of that was Shiki alone). Together they bring the content rendering footprint to roughly 27 KiB transferred, which also let the team remove the React Server Components pipeline they’d been using to hide the dependency cost. TanStack also unveiled a new visual identity, hiring Andy Beutler as its first dedicated lead designer. <a href="https://daily.dev/feed-by-ids?id=h2X7lJrT7&amp;id=sKYnr4t3U&amp;id=h3KuBuJMf" target="_blank" rel="noopener nofollow">Read more</a></p>
<h2>Figma measures Code Connect impact: 29.5% fewer tokens, 19.6% faster AI tasks</h2>
<p>Figma ran 27 test cases using Claude Sonnet 4.5 and Opus 4.7 to measure what happens when AI coding agents have Code Connect context versus generic React representations. With Code Connect, median token usage dropped 29.5%, task duration fell 19.6%, and code quality improved by a full point on a 1-4 Likert scale. The key driver was coverage — the more components are connected, the better the results. A Coinbase case study confirmed agents stopped fabricating components and started using correct imports directly. <a href="https://daily.dev/posts/a99y4btH1" target="_blank" rel="noopener nofollow">Read more</a></p>
