csg.js
Constructive solid geometry on meshes using BSP trees in JavaScript
csg.js is a JavaScript library implementing constructive solid geometry (CSG) operations on polygonal meshes using BSP trees. With CSG, you build complex 3D shapes by combining primitives using Boolean operations like union, subtract, and intersect. The library focuses on clarity and correctness: its implementation is intentionally concise and readable so developers can understand the algorithm, while still correctly handling tricky edge cases such as overlapping coplanar polygons. A WebGL-based demo shows how two solids can be combined interactively in the browser, making it a great educational tool for learning CSG concepts. The API allows you to create primitives (cubes, spheres, etc.) and then combine or transform them programmatically, producing new mesh geometry for rendering or export. Because it is dependency-light and pure JavaScript, csg.js can be integrated into custom modeling tools, CAD-like apps, games, or procedural modeling pipelines running in the browser or Node. -

dat.GUI
dat.gui is a lightweight controller library for JavaScript
A lightweight graphical user interface for changing variables in JavaScript. The easiest way to use dat.GUI in your code is by using the built source at build/dat.gui.min.js. These built JavaScript files bundle all the necessary dependencies to run dat.GUI. If you're using a server with a Content Security Policy in place that blocks 'unsafe-inline', you will have problems when dat.gui.js tries to inject style information. To get around this, load 'build/dat.gui.css' as an external style sheet. With the npm run build script you can build development and production version of scripts. And with the npm run dev script you can build development version of script and watch for changes. -

dc.js
Multi-Dimensional charting built to work natively with crossfilter
dc.js is a javascript charting library with native crossfilter support, allowing highly efficient exploration on large multi-dimensional datasets (inspired by crossfilter's demo). It leverages d3 to render charts in CSS-friendly SVG format. Charts rendered using dc.js are data driven and reactive and therefore provide instant feedback to user interaction. Dimensional charting built to work natively with crossfilter rendered using d3.js. In dc.js, each chart displays an aggregation of some attributes through the position, size, and color of its elements, and also presents a dimension which can be filtered. When the filter or brush changes, all other charts are updated dynamically, using animated transitions. dc.js is an easy yet powerful javascript library for data visualization and analysis in the browser and on mobile devices. -

deb.js
Minimalistic JavaScript library for debugging in the browser
deb.js is a minimal JavaScript debugging library for browser-based development. It works at the function level by letting developers add a debugging wrapper to existing functions. When those functions run, deb.js groups console output and places logs in clearer execution context. It can show stack traces, passed arguments, and execution time, which helps developers understand how functions behave at runtime. The library is very small and can be added near the top of a page before other scripts. It also had a Chrome extension workflow, making it easier to inject debugging behavior into pages during development. -

document-register-element
A stand-alone working lightweight version of the W3C
document-register-element is a lightweight polyfill that brought Custom Elements APIs to browsers without complete native support. It supports both the older V0 model and much of the V1 specification, including autonomous elements and customized built-in elements. Developers can define components with lifecycle callbacks that respond to creation, connection, removal, and observed attribute changes. The package uses feature detection so modern browsers can retain native behavior instead of receiving unnecessary patches. It can be loaded through npm, CommonJS, AMD, bundlers, a script tag, or a CDN. The repository is archived and deprecated, and its maintainer recommends newer custom-elements packages for current projects. -

electron-vue-admin
Vue electron admin template web
Electron-vue-admin is an admin dashboard scaffold that bundles Vue.js with Electron to deliver a desktop admin experience. It is based on the well-known vue-admin-template and generated with electron-vue tooling via Vue CLI. The project aims to let teams reuse familiar Vue components, routing, and permission models while packaging the app as a cross-platform desktop application. Because it inherits from the template ecosystem, you can incorporate patterns like Element UI components, axios-based API calls, and role-based navigation. It’s useful for internal tools that benefit from native-like desktop packaging, offline capabilities, or OS-level integrations. The repository provides a recognizable structure so Vue developers can get productive quickly without learning a new desktop-specific framework from scratch. -

embed-js
A lightweight plugin to embed emojis, media, maps, tweets, code, etc.
A lightweight JavaScript plugin to embed emojis, media, maps, tweets, code and services. embed.js was developed with a modern JavaScript workflow in mind. To use it, it's recommended you have a build system in place that can transpile ES6, and bundle modules. But at the same time, you get an already transpiled version to make your development easier. If you’re using npm package manager with a module bundler like Webpack or Browserify to consume CommonJS modules, you can use the default UMD build of the plugin by simply requiring it. The render() method renders the resulting string in the block. The .render() method also returns a promise. Optionally you can also pass a string which will be processed by the plugin. -

glfx.js
An image effects library for JavaScript using WebGL
glfx.js is a JavaScript image-effects library that uses WebGL to apply real-time filters and transformations directly in the browser. It exposes a simple API where images are uploaded into GPU textures, processed with shader-based filters, and rendered to a WebGL canvas. Because the work is done on the GPU, many effects that would be too slow in pure JavaScript (like complex blurs, lens effects, or tilt-shift) can run interactively, even on large images. The library is structured around three components: textures (image sources), filters (shader pipelines), and canvases (render targets), making it easy to compose multiple effects. A demo page showcases a variety of filters, from basic brightness/contrast adjustments to more advanced distortions and color manipulations. glfx.js remains a handy reference and solution for anyone needing client-side photo editing, visual effects, or generative graphics powered by WebGL.
