    Redux Thunk

    Redux Thunk

    Thunk middleware for Redux

    Redux Thunk is Thunk middleware for Redux. With basic Redux, only simple synchronous updates can be done by dispatching an action. By adding middleware, you extend the Redux store's abilities, enabling you to write async logic that interacts with the store. A thunk is a function that wraps an expression in order to delay its evaluation. Redux Thunk middleware allows you to write action creators that, rather than return an action will return a function instead. If you want to delay the dispatch of an action, or to dispatch only after meeting a certain condition, then the thunk can be used. Thunks are ideal middleware for a number of cases, in particular for basic Redux side effects logic, complex synchronous logic that must access the store, and simple async logic like AJAX requests.

    TuiCss

    TuiCss

    Text-based user interface CSS library

    TuiCss is a library focused to create web applications using an interface based on ASCII table, like the old MS-DOS applications. This kind of interface is very legible because the ultra-contrast colors used and because the reduced effects used on the components in the view. The base of this project is Turbo Vision Framework, but some other frameworks were also checked to introduce some features to TuiCss, like curses, ncurses, Newt, etc. Check the examples page in the wiki to stay on top of some creations, or check the getting started page to start using this library! To start to use TuiCss in your project, you can just download the repository content and import the files that are in the dist folder with the html directives. Alternatively, you can install the package with NPM.

    Wasp

    Wasp

    A programming language that understands what a web app is

    Wasp (Web Application Specification Language) is a declarative DSL (domain-specific language) for developing, building and deploying modern full-stack web apps with less code. Concepts such as app, page, user, login, frontend, production, etc. are baked into the language, bringing a new level of expressiveness and allowing you to get more work done with fewer lines of code. While describing high-level features with Wasp, you still write the rest of your logic in your favorite technologies (currently React, NodeJS, Prisma). Wasp is in alpha and is therefore likely to change a lot, have bugs and miss important features. Due to its expressiveness, you can create and deploy a production-ready web app from scratch with very few lines of concise, consistent, declarative code. When you need more control than Wasp offers, you can write code in existing technologies such as js/html/css/... and combine it with Wasp code!

    Water.css

    Water.css

    A drop-in collection of CSS styles to make simple websites

    water.css is a “classless” CSS framework that instantly beautifies plain HTML without adding custom classes to your markup. By targeting native HTML elements—headings, paragraphs, forms, tables, and buttons—it applies sensible defaults for spacing, typography, and contrast, producing a clean, readable layout out of the box. The stylesheet is intentionally small and dependency-free, making it a convenient drop-in for prototypes, documentation, and minimalist sites where heavy frameworks are overkill. It includes automatic dark and light themes and exposes CSS variables so you can adjust colors or spacing while keeping the overall aesthetic. Because it respects semantic HTML, it plays well with accessibility tools and reduces the risk of brittle component overrides. The result is a fast path to “good enough” styling that remains easy to customize when a project grows.

    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.

    joi-router

    joi-router

    Configurable, input and output validated routing for koa

    Easy, rich, and fully validated koa routing. koa-joi-router returns a constructor that you use to define your routes. The design is such that you construct multiple router instances, one for each section of your application which you then add as koa middleware. The route definition for the currently matched route is available via ctx.state.route. This object is not the exact same route definition object that was passed into koa-joi-router, nor is it used internally - any changes made to this object will not have an effect on your running application but is available to meet your introspection needs. Validating the output body and/or headers your service generates on a per-status-code basis is supported. This comes in handy when contracts between your API and client are strict e.g. any change in response schema could break your downstream clients. In a very active codebase, this feature buys you stability. If the output is invalid, an HTTP status 500 will be used.
