Developer builds custom Windows CLI command to auto-generate JWT secrets in Node.js

A developer working on Node.js and Express projects created a lightweight Windows command-line tool called 'jwt' to eliminate the repetitive task of manually generating JWT secrets for .env files. The tool is a simple .cmd script that uses Node.js's built-in crypto module to produce cryptographically secure random hex strings, requiring no additional npm packages. Users can run 'jwt' for a default 32-byte secret or pass a custom argument like 'jwt 64' to specify a different byte length. The script was placed in a local bin folder and made globally accessible by adding that folder to the Windows User PATH environment variable. The project served as a practical lesson in Windows PATH configuration, .cmd scripting, command-line arguments, and Node.js cryptography.
