TanStack Charts

markdown-graphs is a collection of React components for ASCII-style tables, charts, and diagrams in MDX. It provides more than 30 graph components, including tables, bar charts, sparklines, heat maps, Gantt charts, timelines, trees, and flow diagrams. Components render inside dashed frames using text glyphs and blocks rather than SVG, with optional single-, dual-, or three-accent palettes. The project distributes source files through a shadcn registry: users can add individual components or the full collection to an existing shadcn project, then import them locally. It is not an npm package and requires an existing shadcn project and Motion. The repository is licensed under MIT.

Sandpack is a React component toolkit for embedding live-running code editing and preview experiences in web applications. It runs JavaScript and Node.js applications in the browser and can be used for interactive documentation, coding environments, low-code tools, generated website previews, and embedded playgrounds. Sandpack provides templates containing project files and dependencies, custom setup for changing dependencies or file structure, configurable built-in components, themes, and composable components and hooks for custom interfaces. It uses CodeMirror for editor functionality, supports npm dependencies, hot module reloading, error overlays, caching, and Node.js execution through its Nodebox runtime. The Sandpack Client package exposes a framework-agnostic bundler protocol, and the toolkit supports frameworks including Next.js, Remix, Vite, and Astro.

rataflow is a Rust library for building interactive node-based user interfaces in the terminal, from static diagrams to editable graph views. It is built on ratatui and inspired by xyflow (React Flow). The library provides generic nodes and edges, parent-child hierarchies, configurable interaction flags, dragging, resizing, connection and reconnection, selection, pan and zoom, keyboard navigation, context-menu events, connection validation, and automatic edge-of-canvas panning. It renders custom node and edge content, includes built-in edge types and companion widgets such as controls, a minimap, and a background, and supports runtime palettes and layered Sugiyama layout. Graph snapshots can be serialized with serde, while handlers return semantic FlowEvent values without hidden graph mutations. Input backends include crossterm, termion, termwiz, and WebAssembly through ratzilla; the project also provides browser examples compiled to WASM.

Sugar High is a lightweight, zero-dependency JavaScript syntax-highlighting library that runs in browsers and JavaScript runtimes and converts source code to HTML without requiring a DOM. It supports JavaScript, TypeScript, CSS, Python, C, Go, Java, Rust, JSON, Markdown, SQL, HTML, YAML, and other built-in languages and formats, with alias normalization for inputs such as filename extensions and Markdown fences. The library exposes a one-step highlight function and a composable core that separates syntax parsing from HTML rendering. Token classes can be customized with class maps or token hooks, while line-level hooks support highlighting or modifying generated lines; CSS custom properties provide theming. Its React package supplies Code and textarea-overlay Editor components, and its Remark plugin highlights fenced code blocks during Markdown processing. Sugar High also provides an opt-in experimental WebGPU entry for asynchronous, language-agnostic highlighting through gpu-lexer. It is distributed as npm packages under the MIT license, with a separate core entry for selective language configurations.

hqtui is a TypeScript terminal UI library developed by profullstack for building btop-style dashboards with a one-import API and zero runtime dependencies. It renders directly through ANSI/VT sequences using a typed-array cell framebuffer, differential rendering, truecolor with automatic 256- and 16-color fallback, and Braille or block graphics, without ncurses, a browser DOM, React, native add-ons, or network access. Its API provides layouts, panels, tables, trees, logs, meters, graphs, forms, dialogs, themes, mouse input, and responsive terminal handling. A headless renderer can produce text, screen, ANSI, or HTML output for testing without a TTY. Bun is the default runtime; Node 22.6 or newer is supported, with best-effort Deno support. The project is MIT-licensed and includes a demo dashboard with real or simulated system metrics.
