Please visit thi.ng for additional information & topic based search of packages relevant to your use cases...

This project is NOT a framework and all packages can be used in isolation.

This mono-repository is home to 190 individual TypeScript libraries/packages and 155 example projects illustrating their usage, currently totalling ~200k SLOC and ~3890 source files...

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
• PEG-style functional parser combinators w/ (optional) custom grammar definition language
• Customizable HTML & Markdown parsers
• 2D 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 usually only expect certain interfaces/type signatures rather than hard-coded concrete implementations.

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.ng internal runtime dependencies (w/ very few exceptions! All dependencies are listed in each package readme)
• declare public interfaces, enums & types in an api.ts file
• 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 150+ 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.

Documentation and changelogs for all packages: docs.thi.ng

If you're unsure about something, please reach out! Any constructive feedback is highly appreciated!

Project templates

You might find one of the following template repos an useful starting point:

• 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

Examples & Showcase

There's a steadily growing number (~150) of standalone examples of different complexities (often combining functionality from several packages) in the examples directory.

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!

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)

# or

(cd packages/transducers && yarn build:esbuild)

Note: The yarn build script alias will also generate TS type declaration files. This step is only needed 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)

Tests for almost all packages are run via bun.sh. For a couple of packages we're still 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

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 approx. 800 of them in this repo, but currently only ~15-20% are prepared for extraction so far (it's an ongoing timeconsuming manual process to prepare & check each of them, but work is under way!)

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:

• Mastodon post #1
• Mastodon post #2
• thi.ng/tangle readme

To extract code blocks as source files from readmes:

# in the repo root (to process all packages)
yarn doc:readme

# for a single package only
(cd packages/ && yarn doc:readme)

To extract example code blocks from doc strings (API docs) in source code:

# in the repo root (to process all packages)
yarn tool:tangle

# for a single package only
(cd packages/ && 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:

bun 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:

• bun
• esbuild
• html-minifier-terser
• rimraf
• typedoc
• TypeScript
• Vite
• @thi.ng/monopub
