The envinfo npm package is a tool that generates information about the development environment. It can be used to report system information, software versions, and configuration details, which is particularly useful for debugging and issue reporting in software projects.
System Information
This command prints information about the system, such as OS, CPU, Memory, and Shell.
envinfo --systemBrowsers
This command lists installed web browsers and their versions.
envinfo --browsersLanguages
This command shows the installed languages and their versions, like Node.js, Python, Ruby, etc.
envinfo --languagesUtilities
This command provides information about installed utilities like Git, Make, GCC, etc.

envinfo --sdksCustom Configuration
This command allows for custom configuration to include duplicate packages in the output and the full dependency tree.
envinfo --duplicates --fullTreeThe systeminformation package provides detailed information about the system hardware and software. It offers a broader range of system metrics compared to envinfo, but it does not focus on the development environment configuration.
The os package is a core Node.js module that provides basic operating system-related utility functions. It is more limited in scope compared to envinfo and does not provide information about software versions or development tools.
The which package is a simple utility to find the path of the executable files in the system. It is much more specific in functionality compared to envinfo, which provides a comprehensive report of the environment.
Please mention other relevant information such as the browser version, Node.js version, Operating System and programming language.
To use as a CLI tool, install this package globally:
npm install -g envinfo || yarn global add envinfo
Or, use without installing with npx:

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 => console.log(env));

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"
