envinfo generates a report of the common details needed when troubleshooting software issues, such as your operating system, binary versions, browsers, installed languages, and more

---

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';

console.log(
    envinfo.run(
        {
            System: ['OS', 'CPU'],
            Binaries: ['Node', 'Yarn', 'npm'],
            Browsers: ['Chrome', 'Firefox', 'Safari'],
            npmPackages: ['styled-components', 'babel-plugin-styled-components'],
        },
        { json: 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:

import { helpers } from 'envinfo';

const OS = helpers.getOperatingSystemInfo();
const docker = helpers.getDockerVersion();

console.log({ OS, docker });

{
 OS: 'macOS High Sierra 10.13'
 docker: '17.12.0-ce, build c97c6d6'
}

Contributing

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.

Alternatives

• type $ command -v until you smash your computer
• screenfetch - fetch system and terminal information, and display a pretty ascii logo
• Solidarity - a project based environment checker
• write your own
