The Credential Management API lets your site securely store and retrieve user credentials through the browser’s built‑in manager—no brittle autofill hacks required. In our demo, a successful login stores a PasswordCredential, and a single click later retrieves and auto-fills it for returning users. It’s a progressive enhancement: your form still works everywhere, but supported browsers deliver a faster, lower-friction sign-in. Pair it with proper autocomplete attributes today, and plan for WebAuthn/passkeys to level up tomorrow.

The Contact Picker API lets mobile web apps open the native contacts chooser so users can share exactly the fields you request—like name, phone, email, address, or avatar—without granting blanket access to their entire address book. It’s user-initiated, privacy-preserving, and perfect for speeding up invites and form fills.

Ever find yourself relying solely on console.log() for debugging? You’re missing out on the Console API’s full potential. This powerful debugging toolkit offers specialized methods for timing operations, inspecting complex objects, tracing function calls, and organizing your debugging output. In just minutes, you can elevate your troubleshooting skills from basic to professional-grade. Let’s explore how the Console API can transform your development workflow and help you solve bugs more efficiently than ever before.

The Compute Pressure API lets web apps sense system strain (CPU and thermals) and adapt in real time—preventing throttling, stutter, and battery drain.
