    Kickstart

    Kickstart

    Kickstart is a CSS library designed for modularity and fast page

    Kickstart's CSS is only 80kb and even smaller when you roll your own from the Sass mixins. Not only is the Kickstart JS smaller than Bootstrap and Foundation, it also doesn't require jQuery--drastically reducing page load times. Kickstart has been used in production websites for over three years. Kickstart is a library, not a framework. This means you only use the CSS you need instead of slowing down your site with a complete UI library. Look how easy it is to create this Navbar. Most components in Kickstart require only one mixin to bring markup to life. For users preferring a static CSS file, simple CSS classes are available to quickly write up components. The Kickstart documentation can be toggled between static- and mixin-usage. Kickstart has a lot of components, but it's also extendible.

    Koa

    Koa

    Expressive middleware for node.js using ES2017 async functions

    Koa is a minimal, expressive web framework for Node.js created by the team behind Express, built around modern JavaScript features. Its middleware system uses async functions and an “onion” execution model, producing clean, sequential control flow for request/response handling. Koa keeps the core small and unopinionated—there’s no built-in router or templating—so developers compose only the pieces they need. The framework exposes a refined Context object to standardize request and response utilities without obscuring Node’s primitives. This design encourages readable middleware, robust error handling, and straightforward composition for tasks like authentication, logging, and body parsing. In production, Koa’s simplicity and async-first approach translate to predictable performance and maintainable server code.
