Set Cookies via String

Question

I'd like to use requestjs to make requests and share the cookies between multiple javascript files and even multiple servers. For that reason I'm storing the cookies in a database as a string and retrieve them when needed.

The string looks like this which should be compliant to tough-cookie

[{"domain":"domain.com","path":"/","secure":true,"expires":"2018-06-19T15:36:04.000Z","key":"key1","value":"val1","httpOnly":false,"hostOnly":true},{"domain":"domain.com","path":"/","secure":true,"expires":"2018-06-19T15:36:04.000Z","key":"key2","value":"val2","httpOnly":false,"hostOnly":true}]

How can I get requestjs to use those cookies? The tough-cookie object has a method fromJSON(string) which I suppose is what I need.

So supposedly I think I should be able to do

var cookies = '[{"domain":"domain.com","path":"/","secure":true,"expires":"2018-06-19T15:36:04.000Z","key":"key1","value":"val1","httpOnly":false,"hostOnly":true},{"domain":"domain.com","path":"/","secure":true,"expires":"2018-06-19T15:36:04.000Z","key":"key2","value":"val2","httpOnly":false,"hostOnly":true}]';

var j = request.jar();
j.fromJSON(cookies);

request.get({ url: 'https:/url.com', jar : j}, 
function(error, response, body) {
         console.log(body);
});

but this gives the error TypeError: j.fromJSON is not a function

How can I get request to use the cookies string fetched from the database?

It works to directly access the object to input the cookies but I don't know if this is the best solution:

TOUGH = require('tough-cookie');

var cookies = '[{"domain":"domain.com","path":"/","secure":true,"expires":"2018-06-19T15:36:04.000Z","key":"key1","value":"val1","httpOnly":false,"hostOnly":true},{"domain":"domain.com","path":"/","secure":true,"expires":"2018-06-19T15:36:04.000Z","key":"key2","value":"val2","httpOnly":false,"hostOnly":true}]';

var j = request.jar();
cookies = JSON.parse(cookies);
for(i = 0; i < cookies.length; i++) {
    var cookie = new TOUGH.Cookie(cookies[i]);
       var domain = cookie.canonicalizedDomain();

       if (!j._jar.store.idx[domain]) {
        j._jar.store.idx[domain] = {};
    }
    if (!j._jar.store.idx[domain][cookie.path]) {
        j._jar.store.idx[domain][cookie.path] = {};
    }

j._jar.store.idx[domain][cookie.path][cookie.key] = cookie;
}

//this will use the set cookies

request.get({ url: 'https:/url.com', jar : j}, 
function(error, response, body) {
         console.log(body);
});
