stdlib-js/streams-node-stdout

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 onGitHub, and please considerfinancially supporting stdlib. We greatly appreciate your continued support!

Installation

npm install @stdlib/streams-node-stdout

Alternatively,

  • To load the package in a website via ascript tag without installation and bundlers, use theES Module available on theesm branch (seeREADME).
  • If you are using Deno, visit thedeno branch (seeREADME for usage intructions).
  • For use in Observable, or in browser/node environments, use theUniversal Module Definition (UMD) build available on theumd branch (seeREADME).

Thebranches.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

varstdout=require('@stdlib/streams-node-stdout');

stdout

Standard output as aWritable stream.

// Write to the terminal...stdout.write('beep','utf8');// e.g., => 'beep'

Notes

  • Unlike other streams,stdout cannever be closed and, thus, never emits a'finish' event.
  • Although rare, writes can block when output is redirected to a file.

Examples

varproc=require('process');varstdin=require('@stdlib/streams-node-stdin');varstdout=require('@stdlib/streams-node-stdout');// Set the encoding:stdin.setEncoding('utf8');// Create an echo stream:stdin.pipe(stdout);// Push data to `stdin`:stdin.push('beep');stdin.push(' ');stdin.push('boop');stdin.push('\n');// End the stream:stdin.push(null);// Ensure the process closes:setTimeout(proc.exit,1000);

Notice

This package is part ofstdlib, 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.
