Let's say I have a bash script that calls a node script. I've tried to do it like this:

b.sh file:

#!/bin/bash

v=$(node app.js)

echo $v

app.js file:

#!/usr/bin/env node

function f() {

   return test;

}

return f();

How do I access the value returned by the node script (test) from my bash script ?

@Daniel Lizik gave an good answer (now deleted) for the part: how to output the value, e.g. using his answer:

#!/usr/bin/env node

function f() {

   return test;

}

console.log(f())

And for the part how to capture the value in bash, do exactly as in your question:

#!/bin/bash

val=$(node app.js)

echo node returned: $val

the above prints:

node returned: test
