About
"A collection of functional programming libraries that can be composed together. Unlike a framework, thi.ng is a suite of instruments and you (the user) must be the composer of. Geared towards versatility, not any specific type of music." — @loganpowell via Twitter
Please visit thi.ng for additional information. You might also find the following tools useful to find & explore projects in this vast ecosystem:
This project is NOT a framework and all packages can be used in isolation.
Not including deprecations, this mono-repository is home to 209 individual TypeScript libraries/packages/tools and ~185 example projects illustrating their usage, currently totalling ~238k SLOC and ~4250 source files... Some of the projects have been in regular development since 2015. The monorepo exists in its current form since January 2018.
Unlike most other large mono-repos, this one is not for a single project, but a broad collection of jointly developed, yet independent libraries, tools and general purpose building blocks for the following non-exhaustive list of topics (see package overview below):
- Functional programming (ES6 iterators/generators, composition, memoization, transducers, multi-methods)
- Reactive programming, stream / transducer based dataflow graphs / pipelines / DOM
- Fiber process tree abstraction for ES6 generators (co-routines / cooperative multitasking)
- Data structures & data transformations for wide range of use cases (maps, sets, heaps, queues, graphs etc.)
- WebAssembly bridge APIs & data structure bindings code generators for multiple target languages (primarily aimed at Zig & C11)
- PEG-style functional parser combinators w/ (optional) custom grammar definition language
- Customizable HTML & Markdown parsers
- 2D/3D geometry generation, shape primitives, math, manipulation, intersections, conversions & visualizations
- Canvas abstractions, pixel buffers & SVG serialization/conversion
- Comprehensive function collection (900+) for nD-vectors and matrices (dense & sparse)
- ECS implementations with optional support for strided memory layouts
- Semi-declarative WebGL 1/2 abstraction layer
- DSL for shader functions defined in TypeScript and cross-compilation to GLSL, JS, VEX etc.
- Value-based equivalence (vs. native object identity) and associative data structures (sets, maps)
- DSP building blocks: oscillators, noise generators, filters, 1D FFT/IFFT, muxers, rate converters
- Immutable data handling, state containers, transacted state updates, Undo-Redo history
- Reactive UI component toolkits (DOM-based, canvas-based, immediate-mode, multiple approaches...)
- Multi-format, multi-channel pixel buffers (int & float based), conversions, dithering, Porter-Duff alpha-blending operators
- Color space/format conversions, matrix based color manipulation, gradient generators, color palettes, dominant color extraction
- Date-time abstraction, relative dates, iterators, formatters, math
- WebWorker workflow abstractions
- Forth-style pointfree DSL for functional composition and DSL development/extension
- S-expression parser & runtime (interpreter) infrastructure for custom DSL creation
- WASM-based SIMD batch-processing of vector data
- Pen-plotter (AxiDraw) toolchain & geometry conversions
- Interpolations, math helpers, automatic differentiation (Dual numbers)
- etc.
Once more, this project is NOT a framework. There's no turn-key, one-size-fits-all approach and instead the overall design philosophy encourages a mix & match philosophy for key aspects of application design (inside & outside the browser). Customization points are provided wherever useful and only expect certain interfaces/type signatures rather than hard-coded concrete implementations. In many cases presets are provided too.
All packages:
- are versioned independently
- have auto-generated online documentation at docs.thi.ng
- built via esbuild and tested via bun.sh
- released via thi.ng/monopub publishing toolchain
- distributed as ESM modules (ES2022 syntax) with export maps, TypeScript typings & change logs
- highly modular with often only a single function / class (incl. closely related functions) per file to help w/ selective imports and tree shaking
- provide re-exports of all their publics for full library imports
- have either none or only
@thi.nginternal runtime dependencies (w/ very few exceptions! All dependencies are listed in each package readme) - declare public interfaces, enums & types in an
api.tsfile - licensed under Apache Software License 2.0
Getting started
A common misconception is to think of this repo as single project. It is not! The sheer number and varied nature & purpose of these packages makes it impossible to provide traditional "Getting started" tutorials — there would have to be dozens of them... To compensate, this repo provides ~180 example projects, detailed package readmes (at the very least for all the larger and/or more important ones), as well as hundreds of small usage examples/snippets in doc strings & readme files.
Documentation
- Generated API docs (overview)
- Single page API docs for all pacakges (work-in-progress)
- Hundreds of usage examples/snippets
If you're unsure about something, please reach out! Any constructive feedback is always highly appreciated!
Project templates
You might find one of the following template repos an useful starting point (only updated sporadically, make sure to update dependencies manually):
- tpl-umbrella-basic: Bare-bones template repo for browser-based projects
- tpl-umbrella-fxhash: Project template repo for generative art projects on the fx(hash) platform
- tpl-umbrella-zig: Minimal browser project template for hybrid TypeScript & Zig (WebAssembly) apps

The following packages have been deprecated. Their readmes describe reasons and alternatives:
| Project | Version | Changelog | Description |
|---|---|---|---|
@thi.ng/fsm |  | changelog | FSM / parser primitives |

Building
1git clone https://github.com/thi-ng/umbrella.git 2cd umbrella 3 4yarn install 5yarn build
Once the entire mono-repo has been fully built at least once before, individual packages can then be (re)built like so:
1yarn workspace @thi.ng/transducers run build 2 3# or 4 5(cd packages/transducers && yarn build) 6 7# or 8 9(cd packages/transducers && yarn build:esbuild)
Note: The yarn build script alias will also generate TS type declaration
files. This step is only needed once in the beginning or if updating the public
API of a package. If you're confident it's not needed, using the build:esbuild
alias is sufficient and much faster. Also, TS declaration files can be manually
rebuilt via build:decl...
Building example projects
Please see the example build instructions in the wiki for further details.
Testing
(Most, but not all packages have tests)
Test for all packages are run via bun.sh.
1# build all packages, then run all tests (in one go) 2yarn test 3 4# only run all tests 5yarn test:only 6 7# or individually 8yarn workspace @thi.ng/rstream run test
Building API docs
Autogenerated documentation (using
TypeDoc) will be saved under
/packages/*/doc/ (more info).
1yarn doc
Extracting code examples from readme files & comments
All packages in this repo have prepared infrastructure to extract various code examples & snippets from their README files and from comments in the source code. Altogether, there're 800-1000 of them in this repo, but only ~420 have been processed thus far (it's an ongoing time consuming manual process to prepare & check each of them, but work is under way! Please get in touch if you want to help!).
The code extraction is handled via thi.ng/tangle, itself a part of thi.ng/umbrella. You can read more details about this process here:
To extract code blocks as source files from readmes:
1# in the repo root (to process all packages) 2yarn doc:readme 3 4# for a single package only 5(cd packages/<name> && yarn doc:readme)
To extract example code blocks from doc strings (API docs) in source code:
1# in the repo root (to process all packages) 2yarn tool:tangle 3 4# for a single package only 5(cd packages/<name> && yarn tool:tangle)
In all cases, the extracted files will be saved in each package's /export
folder and can then be run directly via bun:
1bun packages/arrays/export/topo-sort.ts
Acknowledgements
Maintaining a large monorepo like this requires a lot of infrastructure and I'm grateful for the tooling provided by the following projects to simplify those tasks:
