Twilio Function template for calling other functions

fn.js

exports.handler = function(context, event, callback) {
    let path = Runtime.getFunctions()['function_name'].path;
    let fn = require(path);

    fn.handler(context, event, (error, response) => {
        if (error) {
            console.log(error);
            // handle error case
        } else {
            console.log(response);
            // handle response
        }
    });
};
