    goober

    goober

    A less than 1KB css-in-js solution

    As the subtitle notes, this is the smallest and fullest featured css-in-js solution out there. Weighing at 1KB and once bundled it's gonna be less due to tree-shake. goober does more with less! Since the code measure less in size, it's served, read and ran quicker. goober is built on the shoulders of well-established solutions. That means the API has been paved and we need to follow it. You'll find as, forwarded, CSS, keyframes, styled and so much more. Easily access your common sizes, colors, and anything really with the use of a theme. On the server, you can easily extract the CSS for the current state with extractCss. The initial thought of goober was a CSS-in-js solution at the cost of peanuts. Hence the peanuts emoji. By using goober, you are practically getting back space in size to build more of the needed features.

    PRTG Catches Network Issues Before They Cause Downtime

    Threshold-based alerts flag problems early, so your team can act before users notice, not after.

    Reactive troubleshooting usually means hearing about a problem from frustrated users, not your monitoring tool. PRTG sets threshold-based alerts across devices, servers and applications, notifying your team by email, SMS or push the moment a metric crosses a set limit. That means catching a failing disk or overloaded server before it becomes an outage and getting time back from firefighting. Start a free trial and set your first alerts today.

    hapi

    hapi

    The simple, secure framework developers trust

    Build powerful, scalable applications, with minimal overhead and full out-of-the-box functionality. Originally developed to handle Walmart’s Black Friday scale, hapi continues to be the proven choice for enterprise-grade backend needs. When you npm install @hapi/hapi, every single line of code you get has been verified. You never have to worry about some deep dependency being poorly maintained (or handed over to someone sketchy). hapi is the only leading node framework without any external code dependencies. None. hapi has been pushing the envelope on quality from day one. It was the first node framework to require and achieve 100% code coverage across every dependency – when everyone thought it was crazy. Every hapi feature is designed to make the platform easier and more intuitive to use. That means there’s no need to hack things together, experiment to see what *might* work, or try to figure out hidden internals. There is no “magic” – the code does what you expect.

    jQuery Transit

    jQuery Transit

    Super-smooth CSS3 transformations and transitions for jQuery

    jQuery Transit is a classic jQuery plugin that brought ergonomic, chainable CSS3 transitions and transforms to web apps before modern animation APIs were commonplace. It exposes a simple .transition() method so you can animate transforms, opacity, colors, and other CSS properties with minimal code. Under the hood, it leans on GPU-accelerated CSS transforms where available, falling back gracefully, which made complex motion feel smooth even on modest devices. The plugin abstracts away vendor prefixes and browser quirks from an era with inconsistent CSS3 support, letting teams focus on intent instead of compatibility. It integrates with the jQuery queue system, so transitions can be sequenced or synchronized with other effects without race conditions. Although many apps now use native Web Animations or libraries like GSAP/Framer Motion, jquery.transit remains a compact, readable reference for CSS transition ergonomics and progressive enhancement.
