Programmatic Usage

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

import envinfo from 'envinfo';

envinfo.run(
    {
        System: ['OS', 'CPU'],
        Binaries: ['Node', 'Yarn', 'npm'],
        Browsers: ['Chrome', 'Firefox', 'Safari'],
        npmPackages: ['styled-components', 'babel-plugin-styled-components'],
    },
    { json: true, showNotFound: true }
).then(env =&gt; console.log(env));

logs:

{
    "System": {
        "OS": "macOS High Sierra 10.13",
        "CPU": "x64 Intel(R) Core(TM) i7-4870HQ CPU @ 2.50GHz"
    },
    "Binaries": {
        "Node": {
            "version": "8.11.0",
            "path": "~/.nvm/versions/node/v8.11.0/bin/node"
        },
        "Yarn": {
            "version": "1.5.1",
            "path": "~/.yarn/bin/yarn"
        },
        "npm": {
            "version": "5.6.0",
            "path": "~/.nvm/versions/node/v8.11.0/bin/npm"
        }
    },

        },
        "Safari": {

        }
    },
    "npmPackages": {
        "styled-components": {
            "wanted": "^3.2.1",
            "installed": "3.2.1"
        },
        "babel-plugin-styled-components": "Not Found"
    }
}

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[2]}`); // "Node: 10.9.0 - ~/.nvm/versions/node/v8.14.0/bin/node"

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.
