About

Mono-repository for thi.ng TypeScript/ES6 projects, a wide collection of largely data transformation oriented packages and building blocks for:

  • functional programming (composition, memoization, transducers, multi-methods)
  • stream based, reactive programming, dataflow graphs / pipelines
  • data structures & data transformations for wide range of use cases
  • data driven UI components, event & side effect handling
  • immutable data handling
  • geometry generation, processing & visualization
  • vector & matrix implementations with optional support for strided layouts
  • low-level tooling for binary data, shared memory / WASM / WebGL interop
  • etc. (see package overview below)

...all with a keen eye on simplicity, re-use & minimalism without sacrificing flexibility.

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 rather than concrete implementations.

Most packages:

  • have detailed, individual README files w/ small usage examples
  • are versioned independently
  • distributed in ES6 syntax and multiple format (ESM, CommonJS, UMD) with TypeScript typings & changelogs
  • highly modular with largely only a few closely related functions or single function / class per file to help w/ tree shaking
  • provide re-exports of all their publics for full library imports
  • have either none or only @thi.ng internal runtime dependencies
  • have been used in production
  • declare public interfaces, enums & types in an src/api.ts file (larger packages only)
  • auto-generated online documentation at docs.thi.ng
  • licensed under Apache Software License 2.0

Examples

There's a steadily growing number (40+) of standalone examples (different complexities, often combining functionality from several packages) in the examples directory.
