Couchbase Weekly Updates - October 17, 2025

It’s been one of those weeks where vectors, llamas, and mobile SDKs all walk into a database. From new books on vector search to fresh patterns for high-performance data access, one thing’s clear: if you’re building apps that live beyond the cloud, Couchbase is the best way forward for mobile and edge developers. Let’s get to it.

  • 📘 Vector Search with JavaScript
    Ben Greenberg’s new Pragmatic Programmers title, Vector Search with JavaScript guides developers through building intelligent, AI-powered search systems with Node.js. It’s a great read for anyone looking to blend embeddings and hybrid search into modern apps — including those powered by Couchbase’s flexible JSON and vector features. Get the book>>

  • 🦙 Llamas, With a Chance of JSON
    In Jacob Wood’s post the humble llama gets a shot at a starring role in structured data. A fun reminder that JSON, and Couchbase, can handle the weird and wonderful shapes data takes in the real world. Read the post >>

  • 📱 Mobile That’s Here to Stay
    Developers need mobile databases they can rely on — and Couchbase Mobile delivers. With on-device storage, full CRUD access, and built-in sync, Couchbase Lite and Sync Gateway keep your apps running anywhere, anytime. Check out the SDK comparison repo to see how Couchbase’s mobile SDK stacks up against Atlas SDK, and why it’s the future-proof choice for your next offline-first project. Dive in >>

  • Bulk Get Docs, the Efficient Way
    The new blog post, Bulk Get Documents with Reactive or Async APIs, walks through efficient patterns for fetching many documents in parallel. Whether you’re using reactive streams or async futures, it’s a performance win for developers who want to do more with less latency. Get on in >>

That’s it for this week’s Couchbase Weekly for developers! 💥
