I'd like to load and execute a Javascript function in external Javascript file using Node.js and similarly retrieve back with desired result after execution. Is it possible/not possible? If not, any other alternatives.
Any help regarding this is greatly appreciated.
Yes, you can load another JS file as a module using Node.js module system and function require
. There's quite good description of how to do it in Node.js documentation, take a look int this page .
Basically you have to load your external file calling function require
and passing path to that file:
var externalFunction = require('./path/to/external/file')`;
but to make this work you have to export that function by writing something like
module.exports = functionToExport;
in your external file, where functionToExport
is the name of the function which you want to use.
