The problem

  • It works on my computer
  • "command not found"
  • what version of "command" are you running?
  • what version of "different command" are you running?
  • do you have "insert obscure android sdk version"?
  • every github issue reporting template ever:

Please mention other relevant information such as the browser version, Node.js version, Operating System and programming language.

This solution

  • Gather all of this information in one spot, quickly, and painlessly.

Programmatic Usage

Envinfo takes a configuration object and returns a string (optionally yaml, json or markdown)

import envinfo from 'envinfo';
    System: ['OS', 'CPU'],
    Binaries: ['Node', 'Yarn', 'npm'],
    Browsers: ['Chrome', 'Firefox', 'Safari'],
    npmPackages: ['styled-components', 'babel-plugin-styled-components'],
  { json: true, console: true, showNotFound: true }

All of envinfo's helpers are also exported for use. You can use envinfo as a whole, or just the parts that you need, like this:

const envinfo = require('envinfo');

// each helper returns a promise
const node = await envinfo.helpers.getNodeInfo();

// The promises resolve to an array of values: ["Name", "Version", "Path"]
// e.g. ["Node", "10.9.0", "/usr/local/bin/node"]

console.log(`Node: ${node[1]}`); // "Node: 10.9.0"

envinfo is live in:

envinfo is used in the ISSUE_TEMPLATE of:


  • type command -v until you smash your computer
  • specs - an excellent ruby gem that runs command -v for you on :all-the-things: Great for raw info.
  • screenfetch - fetch system and terminal information, and display a pretty ascii logo
  • Solidarity - a project based environment checker
  • write your own




PRs for additional features are welcome! Run npm run lint && npm run format before committing.

This project came out of a PR to the React Native CLI tool - issues are reported frequently without important environment information, like Node/npm versions.
