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:

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 }
    )
);

returns:

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'
}
