Typed.js
A JavaScript typing animation library
Typed.js is a library that types. Enter in any string, and watch it type at the speed you've set, backspace what it's typed, and begin a new sentence for however many strings you've set. Rather than using the strings array to insert strings, you can place an HTML div on the page and read from it. This allows bots and search engines, as well as users with JavaScript disabled, to see your text on the page. You can pause in the middle of a string for a given amount of time by including an escape character. CSS animations are built upon initialization in JavaScript. But, you can customize them at your will! -

Vizzu
Library for animated data visualizations and data stories
Vizzu is a free, open-source Javascript/C++ library utilizing a generic dataviz engine that generates many types of charts and seamlessly animates between them. It can be used to create static charts but more importantly, it is designed for building animated data stories and interactive explorers as Vizzu enables showing different perspectives of the data that the viewers can easily follow due to the animation. Create a placeholder element that will contain the rendered chart. The Vizzu constructor has to load Vizzu's WebAssembly module asynchronously to prevent blocking the whole page. Because of this, any method except animate() will throw an exception while the library is not initialized. There is an initializing promise in the Vizzu class, which will resolve when initialization is finished. You can call all methods after this promise is resolved. -

CCapture.js
A library to capture canvas-based animations at a fixed framerate
CCapture.js is a JavaScript library designed to capture high-quality recordings of HTML5 canvas animations at a fixed and consistent frame rate. Unlike traditional screen recording tools, it decouples rendering speed from capture speed, allowing developers to generate smooth video outputs even when frames take longer to compute. It works by overriding time-related browser functions such as requestAnimationFrame and Date.now to simulate a stable time progression, ensuring every frame is captured accurately. This approach enables the creation of high-resolution videos, slow-motion sequences, or complex visualizations without dropped frames. The library supports multiple export formats including WebM, GIF, PNG sequences, and JPEG archives, making it flexible for different workflows. It integrates easily into browser-based creative coding environments like Three.js and p5.js, making it especially valuable for artists and developers producing generative visuals. -

It supports dynamic updates, enabling diagrams to respond to user interactions or data changes in real time. The system is particularly useful for applications that require visual modeling, such as workflow editors, architecture diagrams, or educational tools. Its modular design allows customization of rendering and behavior, making it adaptable to various use cases. Overall, DgrmJS offers a practical solution for embedding diagramming capabilities into modern web interfaces. -

Graphite-Web
A highly scalable real-time graphing system
Graphite does two things, it stores numeric time-series data and renders graphs of this data on demand. What Graphite does not do is collect data for you, however, there are some tools out there that know how to send data to graphite. Even though it often requires a little code, sending data to Graphite is very simple. Graphite is an enterprise-scale monitoring tool that runs well on cheap hardware. It was originally designed and written by Chris Davis at Orbitz in 2006 as side project that ultimately grew to be a foundational monitoring tool. In 2008, Orbitz allowed Graphite to be released under the open-source Apache 2.0 license. Since then Chris has continued to work on Graphite and has deployed it at other companies including Sears, where it serves as a pillar of the e-commerce monitoring system. Today many large companies use it. -

PhotoSwipe
JavaScript framework independent image gallery
PhotoSwipe is the first open-source gallery to support JavaScript-based image zooming. Even if a browser’s native zooming has been disabled, image zooming will still work. The gallery’s background will gradually fade out as the user zooms out. When the gesture is complete, the gallery will close. Gesture is added because close button in top right corner might be hard to reach on tall mobile devices while holding in one hand. Images can be changed even when current slide is zoomed. Swiping is not blocked during the transition. PhotoSwipe manipulates the browser’s history so that the user can link to each gallery item and close the gallery via the “back” button. The initial URL is restored when the gallery is closed. PhotoSwipe adds a history record when the gallery is opened, which allows the user to close it via the browser’s “back” button. This feature comes as a module. You can exclude it from the build entirely, or fork it to fit the requirements of your product’s URL structure. -
