Hello @kartik,

You could use "child process" module of nodejs to execute any shell commands or scripts with in nodejs. Let me show you with an example, I am running a shell script(hi.sh) with in nodejs.

hi.sh

echo "Hi There!"

node_program.js

const { exec } = require('child_process');
var yourscript = exec('sh hi.sh',
        (error, stdout, stderr) => {
            console.log(stdout);
            console.log(stderr);
            if (error !== null) {
                console.log(`exec error: ${error}`);
            }
        });

Here, when I run the nodejs file, it will execute the shell file and the output would be:

Run

node node_program.js

output

Hi There!

You can execute any script just by mentioning the shell command or shell script in exec callback.

Hope it helps!!
