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 & topic based search of packages relevant to your use cases...

This mono-repository is home to 169+ thi.ng TypeScript/ES6 projects, a wide and jointly developed collection of packages and building blocks for (non-exhaustive list of topics):

  • Functional programming (ES6 iterators/generators, composition, memoization, transducers, multi-methods)
  • Reactive programming, stream / transducer based dataflow graphs / pipelines
  • Data structures & data transformations for wide range of use cases (maps, sets, heaps, queues, graphs etc.)
  • 2D geometry generation, shape primitives, math, manipulation, intersections, conversions & visualizations
  • Canvas abstractions, pixel buffers & SVG serialization/conversion
  • Vector, matrix (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
  • DSP building blocks: oscillators, noise generators, filters, 1D FFT/IFFT, muxers, rate converters
  • Immutable data handling, state containers, transacted state updates, Undo-Redo history
  • Data driven 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
  • Date-time abstraction, relative dates, iterators, formatters, math
  • WebWorker workflow abstractions
  • PEG-style functional parser combinators w/ (optional) custom grammar definition language
  • Forth-style pointfree DSL for functional composition and DSL development/extension
  • S-expression parser & runtime (interpreter) infrastructure for custom DSL creation
  • Low-level tooling for binary data, shared memory/WASM/WebGL interop
  • SIMD batch-processing of vector data
  • WebAssembly bridge API & data structure bindings code generators for multiple target languages
  • Various interpolations, math helpers, automatic differentiation (Dual numbers)
  • etc. (see package overview below)

This project is NOT a framework, provides no turn-key, one-size-fits-all approach and instead encourages a mix & match philosophy for various key aspects of application design (in & outside the browser). Most customization points only expect certain interfaces/type signatures rather than concrete implementations.

All packages:

  • are versioned independently
  • distributed as ESM modules (ES2020 syntax) with export maps, TypeScript typings & change logs
  • highly modular with largely only single function / class (only 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.ng internal runtime dependencies
  • declare public interfaces, enums & types in an api.ts and/or constants.ts file (larger packages only)
  • have auto-generated online documentation at docs.thi.ng
  • licensed under Apache Software License 2.0

Getting started

The sheer number and varied nature & purpose of these packages makes it impossible to provide traditional "Getting started" tutorials. To compensate, this repo provides a large number of example projects, detailed readmes (at the very least for all the larger and/or more important packages) and smaller usage examples in the docstrings.

Examples & Showcase

There's a steadily growing number (100+) of standalone examples (different complexities, often combining functionality from several packages) in the examples directory.

Example screenshots (small selection)

awesome.thi.ng

Due to other priorities still very much in its infancy & planning stage, but please help to document your own usage of these packages by contributing project information to the awesome.thi.ng repo, which will be used to build a showcase site... Thank you!

Generative art projects

Several generative art projects by Karsten Schmidt on fx(hash) have been created exclusively with libraries from this collection.

Community, contributing, getting help

Join our little community on our Discord server or get in touch via Twitter or the issue tracker. If you'd like to contribute, please first read this document.

In general, we welcome contributions of all kinds (docs, examples, bug fixes, feature requests, financial contributions etc.). You can find a fairly detailed overview for contributors here: CONTRIBUTING.md.

Note: The default branch for this repo is develop and all PRs should be created based on this branch. This too means, the README files on this branch might refer to yet-unreleased features or packages. Please use the main branch for viewing the most recently released version(s)!.

Also please be sure to check the wiki for other project-wide information, tidbits, useful snippets etc.

Projects

Important changes (10/2021)

All packages are now only published in ESM format (ES2020 syntax) with TypeScript typings. You can find more details & rationale in issue #315.

As a result (and opportunity), many packages have undergone internal restructuring, some have been split up. All are now fully supporting deep-imports (based on declared export maps), leading to drastically smaller userland bundle sizes.

Previously we also created & published CommonJS & UMD formats, but deemed them an unnecessary burden & hindrance, since all important JS tooling/platforms do support ES modules by now.

Building

git clone https://github.com/thi-ng/umbrella.git
cd umbrella

yarn install
yarn build

Once the entire mono-repo has been fully built at least once before, individual packages can then be (re)built like so:

yarn workspace @thi.ng/transducers run build

# or

(cd packages/transducers && yarn build)

Building example projects

Please see the example build instructions in the wiki for further details.

Testing

(Most, but not all packages have tests)

Due to various build/config issues/complexities, we're now using our own minimal test runner @thi.ng/testament

yarn test

# or individually
yarn workspace @thi.ng/rstream run test

Documentation

Autogenerated documentation (using TypeDoc) will be saved under /packages/*/doc/ and is also available at docs.thi.ng.

yarn doc

Furthermore, an experimental tsdoc-based documentation repo provides an alternative markdown output including cross-references between all packages, but currently isn't frequently updated (only every few months):
