    Typed.js

    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...

    LDtk

    LDtk

    Modern, lightweight and efficient 2D level editor

    ...I created this tool from my 20+ years of experience creating various games (including Dead Cells and game jams). To be exact, LDtk is “pay-what-you-want, including free“, even for commercial projects. Everything you create using LDtk is yours. By the way, LDtk is also open-source, so you could even grab the code and adapt it to your needs. Every UI details were carefully designed to make the process of creating levels as smooth as possible. For every new tool out there, there is this moment when you need to write the importer for your fav engine. I’ve been there too: so LDtk offers a Super Simple Export option. ...

    A fully-featured OpenGL and GLFW extension for PHP

    php-glfw brings the GLFW library to the PHP language, enabling native GUI and OpenGL windowing capabilities directly from PHP scripts. This experimental extension allows developers to create real-time graphical applications, games, and simulations in PHP—traditionally a backend web language—by binding low-level graphics and windowing APIs. It opens creative possibilities for developers more comfortable in PHP or looking to prototype desktop applications with web-style syntax. It’s ideal for...

    frame.js

    JavaScript Sequence Editor

    frame.js is a tiny utility for orchestrating frame-based animations with requestAnimationFrame while keeping code clean and predictable. It abstracts the boilerplate of setting up a render loop, tracking elapsed time, and updating callbacks at the right cadence. By providing a simple lifecycle—start, stop, tick—it encourages separation between state updates and rendering, which is essential for smooth visuals. The library aims to be unobtrusive: you can drop it into demos or prototypes...

    Image processing algorithms in pure Go

    A collection of parallel image processing algorithms in pure Go. The aim of this project is simplicity in use and development over absolute high performance, but most algorithms are designed to be efficient and make use of parallelism when available. It uses packages from the standard library whenever possible to reduce dependency use and development abstractions. All operations return image types from the standard library. Package convolution provides the functionality to create and apply a...

    React Three Fiber

    React Three Fiber

    A React renderer for Three.js

    Build your scene declaratively with re-usable, self-contained components that react to state, are readily interactive, and can tap into React's ecosystem. There is no hard dependency on a particular three.js version, it does not wrap or duplicate a single three.js class. It merely expresses three.js in JSX, <mesh /> becomes new THREE.Mesh(), and that happens dynamically. There is no additional overhead. Components participate in a unified render loop outside of React. It outperforms three.js...

    Decorators/view-models for Rails applications

    Draper adds an object-oriented layer of presentation logic to your Rails application. Without Draper, this functionality might have been tangled up in procedural helpers or adding bulk to your models. With Draper decorators, you can wrap your models with presentation-related logic to organize and test this layer of your app much more effectively. Imagine your application has an Article model. With Draper, you'd create a corresponding ArticleDecorator. The decorator wraps the model, and deals...

    uPlot

    Chart for time series, lines, areas, ohlc and bars

    μPlot is a fast, memory-efficient Canvas 2D-based chart for plotting time series, lines, areas, ohlc & bars; from a cold start it can create an interactive chart containing 150,000 data points in 135ms, scaling linearly at ~25,000 pts/ms. In addition to fast initial render, the zooming and cursor performance is by far the best of any similar charting lib; at ~40 KB, it's likely the smallest and fastest time series plotter that doesn't make use of context-limited WebGL shaders or WASM, both...

    A renderer agnostic two-dimensional drawing api for the web

    Two.js is a two-dimensional drawing api geared towards modern web browsers. It is renderer agnostic enabling the same api to draw in multiple contexts: svg, canvas, and webgl. Two.js is deeply inspired by flat motion graphics. As a result, two.js aims to make the creation and animation of flat shapes easier and more concise. At its core two.js relies on a scenegraph. This means that when you draw or create an object (a Two.Path or Two.Group), two actually stores and remembers that. After you...

    GitHub Isometric Contributions extension

    Browser extension for rendering isometric pixel art charts

    This is a browser extension for Chrome/Brave and Firefox that lets you toggle between your regular GitHub contribution chart and an isometric pixel art version. It uses obelisk.js for isometric graphics. Besides being sort of neat looking, this view is interesting in that it highlights the differences between the number of contributions with more granularity. This isn't meant to completely replace the standard 2D graph though, because in most ways it is actually less useful. For example,...
