It explains how Bun compares with npm, Yarn, and pnpm, and discusses its integrated tooling and claimed performance advantages. ### Source excerpt New job? New toolset to explore! In this post I'll be investigating a new JavaScript package manager and runtime environment called bun.sh. You may have noticed on Playwright.Dev's Getting Started / Installation section there are three different ways to install a ui or api test automation framework with the latest version of Playwright: npm init playwright@latest yarn create playwright pnpm create playwright For this blog post I'll be investigating a fourth way, the new toolset they just started using at work, bun.sh. bun create playwright What is npm, yarn, pnpm, and bun? These are called package managers. What is a package? Developing a project, you don't have to figure out how to code everything yourself. You can include in your projects outside libraries, or "packages" of code from from the public JavaScript registry npmjs.com. The problem is that these packages then need to be downloaded, installed, managed, and updated whenever they are updated. JavaScript projects can use a package manager, such as bun, to help this process. When putting together a Playwright automation framework based around JavaScript and TypeScript, Playwright uses the Node.js JavaScript runtime environment, to run its test runner, execute automation scripts, and manage its browser instances.(See Nodejs.org / About ) There is a division of labor: Node.js runs these internal functions like running tests. NPM, Yarn, PNPM, and now Bun handle the packages. Why are there so many package managers? Each has its own specialization. The original NPM is bundled already with Node.js. Yarn is a Facebook toolset that was created when NPM was found to work too slow. PNPM was created to be smaller and therefore faster. And bun was built for quick startup and installation speed, good especially if you have a CI/ CD pipeline that has a LOT of packages to install each time the tests run. NPM, released in 2010, is the Node Package Manager for Node.js, a JavaScript Runtime Environment.

The package installs the OpenTelemetry Injector, SDKs, and auto-instrumentation packages, which activate instrumentation at process startup without application code or deployment-script changes. ### Source excerpt OpenTelemetry as system dependency Setting up OpenTelemetry for your applications and systems depends on where those apps and systems run. Some are very automated, especially Kubernetes, thanks to the OpenTelemetry Operator, or AWS Lambda, with the OpenTelemetry Lambda layers. But the countless Java, .NET, Node.js, and Python apps running directly on Linux hosts have had no such automation. Instrumenting those has meant downloading agents by hand and wiring up environment variables yourself.

The design uses VRF routing protocols over VXLAN-backed VLAN segments and requires IP routing on core switches instead of configuring VLANs and routing protocols for every VRF on every link and device. The lab can run on netlab-enabled infrastructure, a free GitHub Codespace, or an Apple-silicon Mac. ### Source excerpt Did you know that you can implement a VRF-Lite design with VXLAN? All you need are devices that can run VRF routing protocols over VXLAN-backed VLAN segments. Compared to the "traditional" VRF-Lite design, in which you need a set of VLANs on every link and every device running the routing protocol for every VRF, the VXLAN-based design needs just IP routing on the core switches, resulting in a design that's pretty close to what we were building with DMVPN (without IPsec and NHRP complications).

The lab reproduced the issue on vendor devices, allowing the user to send the topology file to the vendor TAC team for independent reproduction. The article also notes an installation problem involving libvirt, Ubuntu 25.04, and nested virtualization that was subsequently fixed. ### Source excerpt A happy netlab user sent me an unexpected use case: they successfully used its multi-vendor capabilities to argue with a vendor TAC. Here's the gist of the story (edited/anonymized for obvious reasons): They deployed a configuration change that resulted in an unexpected outage. The outage partially disrupted the data center network, so they didn't have the luxury of collecting data and reproducing the issue, as they had to roll back the change as expeditiously as possible.

The company's Slate Switch is a battery-powered smart scene controller that snaps over existing switches, supports tactile local control, and can be used as a portable remote. It is designed to simplify smart-home installation while keeping smart bulbs powered and preserving automations. ### Source excerpt We are often asked if we prioritize "Big Tech" firms in the Works with program, but we've always been clear that newer companies are just as important to our certification as household names. Start-ups are innovators, and have their fingers on the pulse of community needs much more than brands that are only at the mercy of their investors. That's just one reason we're thrilled to welcome zunzunbee to the program! They really stood out from the crowd at CES 2026 this January with their new product, the Slate Switch. This battery-powered smart scene controller simply snaps over existing switches - ideal if you rent your home, or don't fancy working with wiring. We're always on the lookout for devices that make setting up your smart home easier, so we're delighted to have zunzunbee on board! A clean slate for switches While zunzunbee are newcomers to the market, founder Harish Raman has more than 18 years' experience in lighting and connected systems - including senior engineering roles at Leviton and Philips. Harish designed the Slate Switch to cut the complexity sometimes found in smart homes, by bringing back simple, tactile control without any installation headaches. And because it builds on top of your existing switches rather than replacing them, it means less waste and more value from the things you already own.
