thi.ng/umbrella is a broadly scoped monorepo of 215 composable TypeScript libraries (plus ~185 examples) for functional, data-driven development, covering data structures, transducers, reactive programming, geometry, and WebGL/GPGPU visualization. It is explicitly an 'anti-framework' ecosystem where users compose small, independent packages rather than adopting an opinionated stack.

Use cases

• build generative art and creative coding projects in TypeScript
• process data streams with transducers and iterators
• create interactive WebGL or GPGPU visualizations in the browser
• build reactive UIs without a heavyweight framework
• do computational geometry and vector math in TypeScript
• parse custom DSLs with parser combinators
• work with tensors, colors, and data structures functionally

When to choose

• you want small, composable functional TypeScript libraries instead of a monolithic framework
• you're doing creative coding, generative art, or data visualization in the browser
• you need transducers, reactive streams, or geometry utilities with strong typing
• you prefer human-maintained, carefully designed libraries over framework lock-in

When to avoid

• you want a batteries-included framework with a single opinionated way to build apps
• you need a large community, commercial support, or abundant third-party tutorials
• your team is new to functional programming concepts
• you need a single npm package rather than picking from many small ones
