## What it is
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

## Facets
