    bors-ng

    bors-ng

    A merge bot for GitHub Pull Requests

    bors-ng is a GitHub merge bot that enforces an “evergreen” main branch by queueing approved pull requests, testing them together on a staging branch, and only advancing main with the exact, passing commit set. Instead of maintainers repeatedly rebasing and merging one PR at a time, bors-ng batches r+-ed PRs, triggers your existing CI (e.g., GitHub Actions), and merges automatically when the batch is green. If a batch fails, it bisects the batch into smaller runs to isolate the culprit, landing the good PRs and kicking only the failing one(s) back for fixes. The bot is implemented as a GitHub App and works alongside—rather than replacing—your CI by reporting commit statuses/checks and acting on PR comments like bors r+ or bors try. It provides a dashboard to watch queue progress, uses separate staging/trying branches for merge/test cycles, and supports both public GitHub and GitHub Enterprise endpoints.

    dc.js

    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.

    deck.gl

    WebGL2 powered visualization framework

    deck.gl is designed to simplify high-performance, WebGL-based visualization of large data sets. Users can quickly get impressive visual results with minimal effort by composing existing layers, or leveraging deck.gl's extensible architecture to address customer needs. deck.gl maps data (usually an array of JSON objects) into a stack of visual layers - e.g. icons, polygons, texts; and look at them with views: e.g. map, first-person, orthographic. deck.gl handles a number of challenges out of the box. Deck.gl is designed to be highly customizable. All layers come with flexible APIs to allow programmatic control of each aspect of the rendering. All core classes such are easily extendable by the users to address custom use cases. deck.gl is part of vis.gl, an OpenJS Foundation project.

    dejavu

    dejavu

    The missing web UI for Elasticsearch

    dejavu is the missing web UI for Elasticsearch. Existing web UIs leave much to be desired or are built with server-side page rendering techniques that make it less responsive and bulkier to run (I am looking at you, Kibana). We started building dejavu with the goal of creating a modern Web UI (no page reloads, infinite scroll, filtered views, realtime updates, search UI builder) for Elasticsearch with 100% client-side rendering so one can easily run it as a hosted app on github pages, as a chrome extension or as a docker image. Starting v1.0, dejavu is the only Elasticsearch web UI that supports importing data via JSON and CSV files, as well as defining field mappings from the GUI. Starting with v3.0, we support the ability to connect to multiple indexes. You can also globally search across your indexes using global search bar.

    dotenvx

    dotenvx

    A secure dotenv–from the creator of `dotenv`

    dotenvx is an enhanced environment variable loader and manager that builds on the original dotenv concept by adding strong encryption and cross-platform tooling, making it safer to work with .env files in development and production environments. Designed by the creator of the classic dotenv library, dotenvx preserves the familiar workflow while adding safeguards against one of the biggest risks with plain environment files: plaintext secrets exposure. It offers CLI commands that can encrypt and decrypt .env files, inject environment variables at runtime, and support conventions like layered environment file loading similar to Next.js or dotenv-flow. Beyond basic runtime usage, dotenvx includes tooling for key management, listing .env files in structured views, and operations like variable rotation and scoped overrides, bringing more robust secrets handling to modern app stacks.

    frontend-mentor-challenges

    frontend-mentor-challenges

    My submissions for the Frontend Mentor Challenges

    The frontend-mentor-challenges repository contains the author’s submissions to the platform Frontend Mentor — which offers structured UI/UX layout challenges (landing pages, components, form designs) for front-end developers. The codebase shows solutions in HTML, CSS, Javascript, with each challenge typically including an original design file plus the author’s implementation. It’s a great way to practice responsive layouts, CSS grid/flexbox mastery, UI refinement, and build portfolio-worthy front-end snapshots. The README shows that the author has live demos and even a YouTube playlist of walkthroughs. This sort of repository is useful for demonstrating front-end craftsmanship, CSS/HTML mastery, and attention to design detail. It also helps reinforce iteration on design challenges and small reusable components.

    glsl-sandbox

    glsl-sandbox

    Shader editor and gallery

    GLSL Sandbox is an in-browser playground for writing and sharing fragment shaders with instant visual feedback. It provides a minimal editor and a fullscreen WebGL viewport so your shader takes center stage, making it perfect for learning, live-coding, and showcasing visual experiments. The environment injects a small set of uniforms—time, resolution, mouse—so you can animate and interact without boilerplate. A public gallery lets creators browse, fork, and remix shaders, turning the site into a collaborative learning hub. Because everything runs client-side, iteration is fast and portable—just load the page and start typing. It has become a staple tool in the creative-coding community, lowering the barrier to entry for shader art and GPU programming.

    linkedom

    linkedom

    A triple-linked lists based DOM implementation

    linkedom is a lightweight DOM implementation designed for server-side rendering and other environments without a browser DOM. Its triple-linked-list structure aims to keep operations linear and avoid recursion, excessive memory use, and call stack failures on very large documents. It provides DOMParser and parseHTML APIs that return documents, window-like objects, events, elements, and custom element support without polluting global scope. Developers can query content with CSS selectors, create and move nodes, serialize documents, and restore nodes through its JSON format. A worker-focused export supports Deno, Web Workers, and Service Workers without depending strictly on Node.js. LinkeDOM favors speed and minimalism over complete browser emulation, so it is not intended as a fully standards-compliant replacement for JSDOM.

    mui

    mui

    High-performance framework closest to native APP experience

    The gap between performance and experience has always been the primary reason for mobile app developers to abandon HTML5. The browser’s natural page-cutting white screen, the unbearable turning animation, the jittering of floating elements, and the inability to pull down to refresh smoothly, all of which frustrate HTML5 developers, especially when they get a low-end Android machine to run, and the phone falls. On the other hand, the browser default control styles are few and ugly, making a beautiful control is very troublesome, and there are some simple UI frameworks but low performance. The mui framework effectively solves these problems. This is a framework that can facilitate the development of high-performance apps, and it is also the framework that is closest to the effect of native apps.

    mustache.js

    mustache.js

    Minimal templating with {{mustaches}} in JavaScript

    Logic-less templates. mustache.js is a zero-dependency implementation of the mustache template system in JavaScript. Mustache is a logic-less template syntax. It can be used for HTML, config files, source code - anything. It works by expanding tags in a template using values provided in a hash or object. We call it "logic-less" because there are no if statements, else clauses, or for loops. Instead there are only tags. Some tags are replaced with a value, some nothing, and others a series of values. Tags are indicated by the double mustaches. {{person}} is a tag, as is {{#person}}. In both examples, we'd refer to person as the key or tag key. All variables are HTML escaped by default. If you want to return unescaped HTML, use the triple mustache: {{{name}}}. You can also use & to unescape a variable: {{& name}}. This may be useful when changing delimiters (see "Set Delimiter" below).

    simple-git-hooks

    simple-git-hooks

    A simple git hooks manager for small projects

    A simple git hooks manager for small projects. A git hook is a command or script that is going to be run every time you perform a git action, like git commit or git push. If the execution of a git hook fails, then the git action aborts. For example, if you want to run linter on every commit to ensure code quality in your project, then you can create a pre-commit hook that would call npx lint-staged. Check out lint-staged. It works really well with simple-git-hooks. You can look up about git hooks on the Pro Git book. simple-git-hooks works well for small-sized projects when you need quickly set up hooks and forget about it. However, this package requires you to manually apply the changes to git hooks. If you update them often, this is probably not the best choice. Also, this package allows you to set only one command per git hook.
