bluebird promises - how to return a promise out of callback?

Question

Let's say I have the following function

chrome.cookies.getAll({domain: 'google.com'}, callbackFn);

where callbackFn should return all the cookies available

now I have a big main() function (I must have this function) and this function must return the cookies of the given page(as a promise).

How should I do it?

Answer 1

You can do

function main(){
    return new Promise(function (resolve/*, reject*/) {
         chrome.cookies.getAll({domain: 'google.com'}, resolve);
    });
}

You'd use it like this:

main().then(function(cookies) {
     // eat cookies
});
