Retire.js
Scanner detecting the use of JavaScript libraries
There is a plethora of JavaScript libraries for use on the web and in node.js apps out there. This greatly simplifies, but we need to stay updated on security fixes. "Using Components with Known Vulnerabilities" is now a part of the OWASP Top 10 and insecure libraries can pose a huge risk for your web app. The goal of Retire.js is to help you detect the use of versions with known vulnerabilities. Scan a web app or node app for use of vulnerable JavaScript libraries and/or node modules. grunt-retire scans your grunt-enabled app for use of vulnerable JavaScript libraries and/or node modules. Scans visited sites for references to insecure libraries and puts warnings in the developer console. An icon on the address bar displays will also indicate if vulnerable libraries were loaded. Retire.js has been adapted as a plugin for the penetration testing tools Burp and OWASP ZAP. -

Jimp
An image processing library written entirely in JavaScript for Node
An image processing library for Node written entirely in JavaScript, with zero native dependencies. If you're using this library with TypeScript the method of importing slightly differs from JavaScript. Instead of using require, you must import it with ES6 default import scheme. If you're using a web bundles (webpack, rollup, parcel) you can benefit from using the module build of jimp. Using the module build will allow your bundler to understand your code better and exclude things you aren't using. If you're using webpack you can set process.browser to true and your build of jimp will exclude certain parts, making it load faster. The static Jimp.read method takes the path to a file, URL, dimensions, a Jimp instance or a buffer and returns a Promise. In some cases, you need to pass additional parameters with an image's URL. -

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. -

Size Limit
Calculate the real cost to run your JS app or lib
Size Limit is a JavaScript performance budget tool that measures the real cost of your JavaScript bundle and prevents regressions by enforcing limits in CI. It calculates not just raw bundle size, but also download and execution time under configurable network conditions, giving a more realistic sense of what users experience. The tool is modular: it offers a CLI and multiple plugins (file, webpack, time) plus presets tailored to different use cases, from big single-page apps to small npm libraries. When integrated with GitHub Actions, CircleCI, or other CI systems, it runs on every commit or pull request, failing the pipeline if a change exceeds the configured budget. It can also annotate pull requests with comments that highlight how the bundle changed, making performance regressions visible to reviewers early. With the --why flag, size-limit can analyze what contributes most to bundle size and show a dependency breakdown (using Statoscope). -

Superfine
Absolutely minimal view layer for building web interfaces
Superfine is a minimal view layer for building web interfaces. Think Hyperapp without the framework—no state machines, effects, or subscriptions, just the absolute bare minimum (1 kB minified+gzipped). Mix it with your favorite state management library or use it standalone for maximum flexibility. When describing how a page looks in Superfine, we don't write markup. Instead, we use the h() and text() functions to create a lightweight representation of the DOM (or virtual DOM for short), and patch() to actually render the DOM. Superfine won't re-create the entire DOM every time we use patch(). By comparing the old and new virtual DOM we are able to change only the parts of the DOM that need to change instead of rendering everything from scratch. -

Swing
A swipeable cards interface
Swing is a JavaScript library designed to create realistic swipeable card interfaces similar to those popularized by dating applications. It provides physics-based animations that simulate natural movement when users drag and release cards, enhancing user interaction and engagement. The library allows developers to build interfaces where elements can be swiped left, right, or in other directions, triggering specific actions. It is highly customizable, enabling control over thresholds, directions, and animation behavior. Swing is lightweight and framework-agnostic, making it easy to integrate into different web projects without heavy dependencies. It is commonly used for building interactive UI components such as recommendation systems or decision-based interfaces. Overall, swing offers a simple yet powerful way to implement gesture-driven interactions in web applications. -

currency.js
A javascript library for handling currencies
currency.js is a lightweight JavaScript library designed to handle currency values with precision by avoiding common floating point arithmetic issues inherent in JavaScript. It achieves this by internally representing values as integers, which allows for accurate calculations even when dealing with decimals. The library provides a simple and intuitive API for performing operations such as addition, subtraction, multiplication, and division on monetary values. It is optimized for performance and minimal footprint, making it ideal for applications where bundle size and speed are important considerations. currency.js also includes formatting capabilities, allowing developers to display currency values in user-friendly formats with customizable symbols and separators. Its simplicity makes it particularly appealing for smaller projects or cases where a full financial library is not required. -

mongoose-paginate-v2
A custom pagination library for Mongoose with customizable labels
mongoose-paginate-v2 is a pagination library having a page wrapper. The main usage of the plugin is you can alter the return value keys directly in the query itself so that you don't need any extra code for transformation. The initial idea of this plugin is loosely based on the mongoose-paginate package by github.com/edwardhotchkiss/. So this can be considered as an upgraded version of mongoose-paginate with many more options. -

react-window
React components for rendering large lists and tabular data
React window works by only rendering part of a large data set (just enough to fill the viewport). This helps address some common performance bottlenecks. It reduces the amount of work (and time) required to render the initial view and to process updates. It reduces the memory footprint by avoiding over-allocation of DOM nodes. react-window is a complete rewrite of react-virtualized. If react-window provides the functionality your project needs, it is strongly recommend that you use it instead of react-virtualized. However if you need features that only react-virtualized provides, you have two options. Use react-virtualized. (It's still widely used by a lot of successful projects!). Or, create a component that decorates one of the react-window primitives and adds the functionality you need. You may even want to release this component to NPM (as its own, standalone package)! -
