stdlib is a standard library for JavaScript and Node.js, with an emphasis on numerical and scientific computing applications. The library provides a collection of robust, high performance libraries for mathematics, statistics, data processing, streams, and more and includes many of the utilities you would expect from a standard library.
This is the GitHub repository of stdlib source code and documentation. For help developing stdlib, see the development guide.
- An extensive collection of standard library mathematical functions.
- Utilities for manipulating floating-point numbers and transforming data.
- Packages for incremental computation of statistics over data streams.
- Large collection of seedable pseudorandom number generators (PRNGs).
- Native add-ons and WebAssembly interfaces for interfacing with BLAS libraries, with pure JavaScript fallbacks.
- Sample datasets for testing and development.
- String manipulation utilities.
- A comprehensive assertion library.
- A benchmark framework which outputs TAP.
- A plot API.
- REPL environment with integrated help and examples.
- Backward compatibility to Node.js
v0.10. - Rigorous testing against reference implementations.
- Can be bundled using Browserify or Webpack for use within web browsers.
- Extensive documentation and examples.
- Commercial friendly license.
Running stdlib requires the following prerequisites:
- Node.js: JavaScript runtime (version
>= 0.10) - npm: package manager (version
> 2.7.0; if Node< 1.0.0, version> 2.7.0and< 4.0.0)
Most functionality in stdlib is implemented exclusively in JavaScript; however, some implementations try to capture performance benefits by using native bindings and/or WebAssembly. While not required to run stdlib, as every stdlib implementation has a JavaScript fallback, the following dependencies are required for building native add-ons, including linking to BLAS and LAPACK libraries:
- GNU make: development utility and task runner
- GNU bash: an sh-compatible shell
- gcc & g++ or Clang: C/C++ compilation and linking (g++ version
>= 4.8; clang version>= 3.5, Xcode version>=8.3.1on OS X) - gfortran: Fortran compilation and linking (version
>= 4.8)
While not required to run stdlib, the following dependencies are required for automatically downloading external libraries:
The following external libraries can be automatically downloaded and compiled from source using make:
To install as a library or application dependency,
$ npm install @stdlib/stdlibOtherwise, to install as a system library, follow the download, configuration, and installation instructions as described in the development guide.
