For development, you will only need Node.js and a node global package
Just go on official Node.js website (https://nodejs.org/) and download the installer.
Run the following command in your project directory:
Open terminal and type - npm install
a) Run directly with command line - node src/auto-run.js "*/15 0 1,15 * 1-5 /usr/bin/find"
b) Run node application and test with an API - Go to command line and run node src\index.js - Use API in postman or any api tool - Method - POST URL - http://localhost:3000/cron Body - { "expression": "30 15 * * * /usr/bin/find" }
You can change input strings and test in terminal you'll see a table of output and with rest api you'll see a json response
