POSTMAN: Global functions from CDN javascript file

postman_load_cdn_js.js

// can be used at a collection level pre-request script to pull a js from a cdn, and expose the methods to all your requests
// can also use a script package instead of a CDN.

await (async () => {
    const requestPromise = new Promise((resolve, reject) => {
        pm.sendRequest("https://cdn.foo.com/foo_utils.js", (err, res) => {
            if (err) {
                console.error(err);
                return reject(err);
            }                
            resolve(res.text());
        });
    });

        //console.log(`response = ${response}`);
        // execute the response so the functions are available
        eval(response);
