Intermock
Mocking library to create mock objects with fake data for TypeScript
Intermock is a TypeScript utility developed by Google that automatically generates mock objects and JSON data for TypeScript interfaces using the Faker library. It simplifies frontend and API testing by creating realistic, schema-compliant mock data directly from interface definitions, eliminating the need for manual mock creation. Intermock supports a wide range of TypeScript constructs including interfaces, unions, generics, mapped types, and tuples, ensuring comprehensive type coverage. It can be used both via a command-line interface (CLI) and programmatically through its API, making it suitable for integration into build pipelines or development environments. The tool also allows fine-grained control over output format—object, JSON, or string—and supports JSDoc annotations to define custom Faker data generators. By leveraging Intermock, developers can quickly generate realistic mock datasets for testing, prototyping, and documentation purposes without writing boilerplate code. -

visx
Visualization components
visx a collection of expressive, low-level visualization primitives for React. At Airbnb, we made it a goal to unify our visualization stack across the company and in the process, we created a new project that brings together the power of D3 with the joy of React. visx is split into multiple packages. Start small and use only what you need. Bring your own state management, animation library, or CSS-in-JS solution. Odds are good your React app already has an opinion on how animation, theming, or styling is done. visx is careful not to add another one and integrates with all of them. As you start using visualization primitives, you’ll end up building your own charting library that’s optimized for your use case. You’re in control. And most importantly, it’s just React. If you know React, you can make visualizations. It’s all the same standard APIs and familiar patterns. visx should feel at home in any React codebase. -

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. -
