    PouchDB

    PouchDB

    The Database that Syncs!

    PouchDB is an open source, pocket-sized JavaScript database that conveniently synchronizes with servers when it gets back online. It’s inspired by Apache CouchDB, so it’s designed to run well within the browser. PouchDB was created to enable web developers to build applications that will work just as well offline as they do online. It enables applications to store data locally while offline, and once back online it will synchronize with CouchDB and compatible servers, so your data will always be in sync. PouchDB works on various browsers, including Chrome, Firefox, Safari and more. It’s very lightweight and though some programming knowledge is required, is still very easy to learn.

    Pure.css

    Pure.css

    A set of small, responsive CSS modules that you can use

    A set of small, responsive CSS modules that you can use in every web project. Pure is ridiculously tiny. The entire set of modules clocks in at 3.7KB* minified and gzipped. Crafted with mobile devices in mind, it was important to us to keep our file sizes small, and every line of CSS was carefully considered. If you decide to only use a subset of these modules, you'll save even more bytes. Pure builds on Normalize.css and provides layout and styling for native HTML elements, plus the most common UI components. It's what you need, without the cruft. Pure is responsive out of the box, so elements look great on all screen sizes. Pure has minimal styles and encourages you to write your application styles on top of it. It's designed to get out of your way and makes it easy to override styles. By using Grids, Menus, and more, it's easy to create beautiful responsive layouts for all screen sizes. We've made it easy for you to get started.

    Reselect

    Reselect

    Selector library for Redux

    Simple “selector” library for Redux (and others) inspired by getters in NuclearJS, subscriptions in re-frame and this proposal from speedskater. Selectors can compute derived data, allowing Redux to store the minimal possible state. Selectors are efficient. A selector is not recomputed unless one of its arguments changes. Selectors are composable. They can be used as input to other selectors. Reselect provides a function createSelector for creating memoized selectors. createSelector takes an array of input-selectors and a transform function as its arguments. If the Redux state tree is mutated in a way that causes the value of an input-selector to change, the selector will call its transform function with the values of the input-selectors as arguments and return the result. If the values of the input-selectors are the same as the previous call to the selector, it will return the previously computed value instead of calling the transform function.

    ScrollMagic

    ScrollMagic

    The javascript library for magical scroll interactions

    ScrollMagic helps you to easily react to the user's current scroll position. ScrollMagic is a complete rewrite of its predecessor Superscrollorama by John Polacek. A plugin-based architecture offers easy customizability and extendability. Animate based on scroll position, pin an element starting at a specific scroll position, toggle CSS classes of elements on and off based on scroll position, effortlessly add parallax effects to your website, create an infinitely scrolling page, add callbacks at specific scroll positions or while scrolling past a specific section. Either trigger an animation or synchronize it to the scrollbar movement (like a playback scrub control). Pin an element starting at a specific scroll position, either indefinitely or for a limited amount of scroll progress (sticky elements). You can add callbacks at specific scroll positions or while scrolling past a specific section, passing a progress parameter.

    Semantic UI React

    Semantic UI React

    The Semantic-UI-React integration

    jQuery is a DOM manipulation library. It reads from and writes to the DOM. React uses a virtual DOM (a JavaScript representation of the real DOM). React only writes patch updates to the DOM, but never reads from it. It is not feasible to keep real DOM manipulations in sync with React's virtual DOM. Because of this, all jQuery functionality has been re-implemented in React. Declarative APIs provide for robust features and prop validation. Control the rendered HTML tag, or render one component as another component. Extra props are passed to the component you are rendering as. Augmentation is powerful. You can compose component features and props without adding extra nested components. This is essential for working with MenuLinks and react-router. Shorthand props generate markup for you, making many use cases a breeze. All object props are spread on the child components. Components with repeating children accept arrays of plain objects.

    Site Kit for WordPress

    Site Kit for WordPress

    Site Kit is a one-stop solution for WordPress users

    Site Kit is a first-party WordPress plugin that brings key Google services into a single dashboard so site owners can see how their content performs and fix issues without leaving wp-admin. After a guided setup and verification flow, it connects properties to Search Console, Analytics, AdSense, PageSpeed Insights, and other services, surfacing the most relevant metrics per page and per site. The plugin focuses on clarity: traffic sources, search queries, top pages, and monetization signals appear alongside actionable performance recommendations. It also handles authentication and permission scopes securely, so multiple collaborators can access insights without sharing credentials. Widgets and contextual panels put data where it’s needed—for example, on the post list or edit screen—reducing tab-switching. For developers and agencies, Site Kit simplifies client onboarding and standardizes reporting across many sites.

    TwitchAdSolutions

    TwitchAdSolutions

    This repo aims to provide multiple solutions for blocking Twitch ads

    TwitchAdSolutions is an open-source repository that aggregates multiple techniques, scripts, and tools designed to block or bypass advertisements on the Twitch streaming platform.

The project focuses on maintaining functional workarounds for Twitch’s evolving ad delivery system, which frequently changes to counter ad-blocking solutions. It includes experimental scripts that attempt to replace or skip ad segments by forcing the player to retrieve ad-free streams or suppress playback during ad breaks. The repository also provides configuration instructions for tools like uBlock Origin, allowing users to integrate custom filters and scripts into their browsing setup.

    V Programming Language

    V Programming Language

    Simple, fast, safe, compiled language for developing software

    Simple language for building maintainable programs. You can learn the entire language by going through the documentation over a weekend, and in most cases, there's only one way to do something. This results in simple, readable, and maintainable code. Despite being simple, V gives a lot of power to the developer and can be used in pretty much every field, including systems programming, webdev, gamedev, GUI, mobile, science, embedded, tooling, etc. V avoids doing unnecessary allocations in the first place by using value types, and string buffers, promoting a simple abstraction-free code style. Most objects (~90-100%) are freed by V's auto-free engine: the compiler inserts necessary free calls automatically during compilation. A remaining small percentage of objects is freed via GC. The developer doesn't need to change anything in their code. "It just works", like in Python, Go, or Java, except there's no heavy GC tracing everything or expensive RC for each object.
