tsup
The simplest and fastest way to bundle your TypeScript libraries
tsup is a zero-config TypeScript/JavaScript bundler focused on developer speed and sensible defaults. It builds on extremely fast tooling under the hood to deliver near-instant feedback loops even in large monorepos. The design goal is to let you publish modern libraries without hand-crafting long build scripts: point it at an entry file and it emits multiple targets, formats, and type declarations. It handles common library needs out of the box—like generating both ESM and CJS, bundling assets, and preserving or treeshaking dependencies—while staying flexible through minimal flags. Because it embraces convention over configuration, it’s easy to adopt as a drop-in replacement for heavier bundlers in simple packages, yet it scales when you need custom externals, minification, or watch modes. The result is a practical tool that shortens the path from source to npm-ready output, lowering maintenance cost across many packages in a repo. -

type-fest
A collection of essential TypeScript types
type-fest is a TypeScript utility types library that offers a curated, battle-tested suite of type definitions and type transformations that aren’t included in the TypeScript standard library. It provides types like Except, Merge, LiteralUnion, Writable, Promisable, PartialDeep, JsonObject, and many others that solve everyday typing needs in complex TypeScript codebases. Developers pull in just the types they need, which makes code more expressive and safer without reinventing tricky type logic. Because many of the types in type-fest are things “that should have been built-in,” it’s widely adopted across TypeScript projects that need more advanced static typing capabilities. The package is modular, well documented, and regularly maintained to stay compatible with evolving TypeScript versions and features. It plays a central role in type-heavy codebases (frameworks, utilities, libraries) by reducing repetition and giving reliable tools for type-level programming. -

zshy
Bundler-free build tool for TypeScript libraries
zshy is a modern build tool aimed at TypeScript library authors who want a bundler-free development experience. Instead of relying on bundlers like Webpack or tsup, zshy leverages the TypeScript compiler (tsc) itself to produce both ESM and CommonJS builds, generate type declarations, and automatically populate "exports" fields in a package’s package.json. It reads configuration directly from package.json and standard TypeScript config files, doesn’t require its own config, and supports multi-entry libraries with deep wildcard exports. Originally created for building popular libraries such as Zod, zshy fills the niche for a straightforward, convention-over-configuration build pipeline for TypeScript packages. The tool copies non-JS assets, supports .tsx, and makes CLI packaging easy, helping maintain consistent library outputs with minimal boilerplate. -

ChartGPU
Beautiful, open source, WebGPU-based charting library
The ChartGPU repository is an open-source, WebGPU-based charting library written in TypeScript that enables developers to visualize large datasets with high performance and smooth interactivity even when handling millions of data points. By leveraging WebGPU — the next-generation graphics API for the web — ChartGPU offloads rendering work to the GPU, allowing for fast panning, zooming, and real-time updates with minimal latency. This makes the library particularly valuable for data-intensive dashboards, scientific visualizations, and financial charting where performance bottlenecks of traditional canvas or SVG approaches become apparent. It includes support for common chart types like line, bar, scatter, and candlestick plots, and its architecture is designed to scale with both visual complexity and data volume. -

Intent UI is a modern React component library focused on accessibility, customization, and developer ownership, built on top of React Aria Components and styled with Tailwind CSS. It follows a copy-and-paste philosophy similar to shadcn/ui, allowing developers to directly integrate and modify components within their own codebases instead of relying on rigid dependencies. The library emphasizes accessible design by leveraging ARIA standards and best practices, ensuring that components work well with keyboard navigation and assistive technologies. It includes a wide range of components such as overlays, forms, visualizations, and layout elements, making it suitable for building full web applications. Intent UI also provides templates, blocks, and starter kits that accelerate development and reduce setup time for new projects.

Mock Service Worker
Seamless REST/GraphQL API mocking library for browser and Node.js
Mock by intercepting requests on the network level. Seamlessly reuse the same mock definition for testing, development, and debugging. A dedicated layer of requests interception at your disposal. Keep your application's code and tests unaware of whether something is mocked or not. Request the same production resources and test the actual behavior of your app. Augment an existing API, or design it as you go, when there is none. Use Express-like routing syntax to capture outgoing requests. Parameters, wildcards, regular expressions, mocking has never been easier. Browser usage is what sets Mock Service Worker apart from other tools. Utilizing the Service Worker API, which can intercept requests for the purpose of caching, Mock Service Worker responds to captured requests with your mock definition on the network level. This way your application knows nothing about the mocking. -

carbon-components-svelte
Svelte implementation of the Carbon Design System
Carbon Components Svelte is a Svelte-native implementation of IBM’s Carbon Design System, built to bring the structure, consistency, and scalability of a mature enterprise design system into Svelte applications. Rather than being a small collection of ad hoc widgets, it functions as a comprehensive component library intended to support design reuse, predictable development, and long-term extensibility across products. Because it is tied to Carbon, the project is especially valuable for teams that want a well-established visual language and interaction model instead of inventing one from scratch. The library also sits within a broader Carbon Svelte ecosystem that includes icon components, pictograms, charts, and preprocessors, which makes it possible to assemble full product interfaces with a unified design vocabulary. Its styling model supports multiple official themes. -

Ink
React for interactive command-line apps
Ink is React for CLIs. It is designed to provide that same component-based UI building experience that React provides, only this time for command-line apps. So if you already know React, then you should know Ink. Apart from being built for CLIs, one other key difference between the two is that with Ink, the rendering doesn’t result in a DOM but a string, which Ink writes to the output. Ink is a React renderer, so all features of React are supported. Dozens of projects currently use Ink. You can check it out live on https://ink-counter-demo.vadimdemedes.repl.run/
