About stdlib...

We believe in a future in which the web is a preferred environment for numerical computation. To help realize this future, we've built stdlib. stdlib is a standard library, with an emphasis on numerical and scientific computation, written in JavaScript (and C) for execution in browsers and in Node.js.

The library is fully decomposable, being architected in such a way that you can swap out and mix and match APIs and functionality to cater to your exact preferences and use cases.

When you use stdlib, you can be absolutely certain that you are using the most thorough, rigorous, well-written, studied, documented, tested, measured, and high-quality code out there.

To join us in bringing numerical computing to the web, get started by checking us out on GitHub, and please consider financially supporting stdlib. We greatly appreciate your continued support!

Process

NPM version Build Status Coverage Status

Process utilities.

Installation

npm install @stdlib/process

Alternatively,

  • To load the package in a website via a script tag without installation and bundlers, use the ES Module available on the esm branch (see README).
  • If you are using Deno, visit the deno branch (see README for usage intructions).
  • For use in Observable, or in browser/node environments, use the Universal Module Definition (UMD) build available on the umd branch (see README).

The branches.md file summarizes the available branches and displays a diagram illustrating their relationships.

To view installation and usage instructions specific to each branch build, be sure to explicitly navigate to the respective README files on each branch, as linked to above.

Usage

var ns = require( '@stdlib/process' );

ns

Namespace containing process utilities.

var proc = ns;
// returns {...}

The namespace contains process utilities:

  • ARGV: array containing command-line arguments passed when launching the calling process.
  • chdir( path ): change the current working directory.
  • cwd(): return the current working directory.
  • ENV: object containing the user environment.
  • EXEC_PATH: absolute pathname of the executable which started the current Node.js process.
  • getegid(): return the effective numeric group identity of the calling process.
  • geteuid(): return the effective numeric user identity of the calling process.
  • getgid(): return the numeric group identity of the calling process.
  • getuid(): return the numeric user identity of the calling process.
  • NODE_VERSION: node version.
  • stdin( [encoding,] clbk ): read data from stdin.
  • umask( [mask,] [options] ): get/set the process mask.

Examples

var objectKeys = require( '@stdlib/utils/keys' );
var ns = require( '@stdlib/process' );

console.log( objectKeys( ns ) );

Notice

This package is part of stdlib, a standard library for JavaScript and Node.js, with an emphasis on numerical and scientific computing. The library provides a collection of robust, high performance libraries for mathematics, statistics, streams, utilities, and more.
