Chartist.js
Simple responsive charts
You may think that this is just yet an other charting library. But Chartist.js is the product of a community that was disappointed about the abilities provided by other charting libraries. Of course there are hundreds of other great charting libraries but after using them there were always tweaks you would have wished for that were not included. Are you planning to use Chartist to create a nice Dashboard or Admin UI? Don't loose any time and kickstart your development using the awesome templates by Creative Tim. They include Chartist and come with awesome chart styles! Specifying the style of your chart in CSS is not only cleaner but also enables you to use awesome CSS animations and transitions to be applied to your SVG elements! Note that CSS3 animations on SVG CSS attributes are not supported on all browsers and the appearance may vary. -

ChatLLM Web
Chat with LLM like Vicuna totally in your browser with WebGPU
Chat with LLM like Vicuna totally in your browser with WebGPU, safely, privately, and with no server. Powered By web-llm. To use this app, you need a browser that supports WebGPU, such as Chrome 113 or Chrome Canary. Chrome versions ≤ 112 are not supported. You will need a GPU with about 6.4GB of memory. If your GPU has less memory, the app will still run, but the response time will be slower. The first time you use the app, you will need to download the model. For the Vicuna-7b model that we are currently using, the download size is about 4GB. After the initial download, the model will be loaded from the browser cache for faster usage. -

Cheerio
Implementation of core jQuery designed for the server
Fast, flexible & lean implementation of core jQuery designed specifically for the server. Cheerio implements a subset of core jQuery. Cheerio removes all the DOM inconsistencies and browser cruft from the jQuery library, revealing its truly gorgeous API. Cheerio works with a very simple, consistent DOM model. As a result parsing, manipulating, and rendering are incredibly efficient. Cheerio wraps around parse5 parser and can optionally use @FB55's forgiving htmlparser2. Cheerio can parse nearly any HTML or XML document. Cheerio parses markup and provides an API for traversing/manipulating the resulting data structure. It does not interpret the result as a web browser does. Specifically, it does not produce a visual rendering, apply CSS, load external resources, or execute JavaScript. If your use case requires any of this functionality, you should consider projects like Puppeteer or JSDom. -

Chinese Poetry
The most comprehensive database of Chinese poetry
This repository is a curated collection of Chinese poems and poets organized into catalogs, metadata, and text representations suitable for research, creative and cultural use. It includes major dynastic corpora, such as Tang and Song poems, as well as biographical and categorization data. Each poem entry is structured with fields like author, dynasty, title, content, and sometimes annotations or alternate versions. Developers and scholars can build tools that query by author, era, keyword, or poetic form using the standardized data structure. Because the project is open, contributors improve metadata, correct text variants, and maintain consistency across classical collections. The corpus enables digital humanities, poetry apps, styling tools, and creative projects that intermix poems with translation, visualization, or musical settings. -

Clean Code JavaScript
Clean Code concepts adapted for JavaScript
clean-code-javascript adapts Robert C. Martin’s Clean Code principles to the JavaScript ecosystem, presenting them as pragmatic, example-driven guidelines rather than a prescriptive style guide. It focuses on writing code that is readable, searchable, testable, and easy to refactor, using before/after (“Bad/Good”) snippets to make each idea concrete. The repository covers everyday concerns—naming, functions, conditionals, objects, classes, and error handling—showing how small choices compound into maintainable systems. Modern JavaScript features (e.g., default parameters, destructuring, classes, array methods) are used to illustrate clearer APIs and fewer side effects. Throughout, the guidance encourages single-purpose functions, avoiding unnecessary context and duplications, and favoring functional patterns where they improve clarity. It’s a reference you dip into to assess your code’s clarity and consistency, not a checklist of rules to follow blindly. -

Code Surfer
Rad code slides
Code Surfer is a presentation tool for creating interactive code-focused slides in MDX Deck. It helps presenters explain code by adding highlighting, zooming, scrolling, focusing, and morphing between code states. The project is designed for technical talks, workshops, tutorials, and conference demos where static screenshots are not expressive enough. It lets authors wrap code blocks inside Code Surfer components and control how the audience moves through the code. This makes it easier to reveal important lines gradually, compare changes, and maintain attention during complex explanations. Code Surfer is best suited for developers who teach programming concepts and want more dynamic code presentations. -

Codex Taskboard
A local-first issue board that runs in a browser
Codex Taskboard is a local-first issue board for organizing development work performed with Codex and related agent workflows. It runs in a browser and can also be embedded directly into Codex through a dedicated launcher or injection script. Projects and issues are stored locally in SQLite and can be managed through both a React interface and the taskctl command-line tool. A bundled Codex Skill teaches agents to inspect issues, change workflow states, verify work, and wait for user acceptance before marking tasks complete. The same local HTTP API powers both the graphical interface and CLI. Native desktop packaging bundles the service, interface, Skill, CLI wrapper, and injection tooling for easier operation. It supports local, LAN, and optional cloud-connected workflows while keeping local path handling on the device. -

CodexPro
Use ChatGPT Developer Mode as a local coding agent for your repo
CodexPro is a local MCP bridge that lets ChatGPT Developer Mode work inside a specific code repository. It starts a local server for the current workspace so ChatGPT can read files, search code, apply scoped edits, run guarded shell checks, and review changes. The project is designed around local control rather than hosting code or proxying model access through a third-party service. It supports setup, start, doctor, settings, handoff, and pro modes for different levels of agent involvement. Public access can be routed through options such as Cloudflare tunnels, ngrok, Tailscale Funnel, or local-only mode. CodexPro is useful for developers who want ChatGPT to act like a repo-aware coding assistant while keeping the actual workspace on their own machine. -

Consola
Elegant Console Logger for Node.js and Browser
Fancy output with fallback for minimal environments. Consistent command-line interface (CLI) experience. Spam prevention by throttling logs. console uses std in the underlying so calling wrapStd redirects console too. The benefit of this function is that things like console.info will be correctly redirected to the corresponding type. Any instance of consola that inherits the mocked instance, will apply provided callback again. This way, mocking works for withTag scoped loggers without the need for extra effort. Choose between one of the built-in reporters or bring in your own one. By default FancyReporter is registered for modern terminals or BasicReporter will be used if running in limited environments such as CIs. A reporter (class or object) exposes log(logObj) method. To get more info about how to write your own reporter, take a look at the linked implementations. -

Context Hub
Makes coding agents get smarter with every task
Context Hub is a curated documentation system built to help coding agents write more accurate code. It gives agents versioned, language-specific reference material instead of forcing them to rely on noisy web searches or stale model memory. The project includes a CLI called chub that agents can use to search for available docs, fetch specific API guidance, and request only the files they need. It also supports local annotations, allowing an agent to remember project-specific notes, pitfalls, or workarounds across future sessions. Feedback can be sent back to maintainers so shared documentation improves over time. Context Hub is especially useful for teams that use AI coding assistants and want more reliable API usage, fewer hallucinated calls, and a transparent source of agent-readable context. -

Conventional Changelog
Generate changelogs and release notes from a project's commit messages
The conventional-changelog repo is managed as a monorepo; it's composed of many npm packages. It's recommended you use the high-level standard-version library, which is a drop-in replacement for npm's version command, handling automated version bumping, tagging, and CHANGELOG generation. Alternatively, if you'd like to move towards completely automating your release process as an output from CI/CD, consider using semantic-release. We specifically limit our support to LTS versions of Node, not because this package won't work on other versions, but because we have a limited amount of time, and supporting LTS offers the greatest return on that investment. It's possible this package will work correctly on newer versions of Node. It may even be possible to use this package on older versions of Node, though that's more unlikely as we'll make every effort to take advantage of features available in the oldest LTS version we support. -

Critters
A Webpack plugin to inline your critical CSS and lazy-load the rest
It's a little different from other options because it doesn't use a headless browser to render content. This tradeoff allows Critters to be very fast and lightweight. It also means Critters inlines all CSS rules used by your document, rather than only those needed for above-the-fold content. Critters' design makes it a good fit when inlining critical CSS for prerendered/SSR'd Single Page Applications. It was developed to be an excellent compliment to the prerender-loader, combining to dramatically improve first paint time for most Single Page Applications. Import Critters into your Webpack configuration and add it to your list of plugins. That's it! Now when you run Webpack, the CSS used by your HTML will be inlined and the imports for your full CSS will be converted to load asynchronously. Create a Critters plugin instance with the given options.
