Enhancing $http Responses in AngularJS: Passing Extra Parameters

Question

Enhancing $http Responses in AngularJS: Passing Extra Parameters

Is there a way to include additional configurations in $http service response? The code snippet below demonstrates the scenario:

var promises = [];
angular.forEach(rows, function(rowIterator) {
    var additionalConfig = {
      config1: rowIterator.config1,
      config2: rowIterator.config2
    }

    promise = $http({
        method: "get",
        url: "http://domain.com/" + rowIterator.videoId + '?appName=playlist',
        params: {}
    });
    promises.push(promise);                   
});

return $q.all(promises).then(function(data) {
    // How can I access fetched data along with the custom configs from 'additionalConfig'?
});

In this case, how do I extract and utilize the data retrieved by $q.all while maintaining the passed configurations from 'additionalConfig'?

Here's an interesting approach you could try to improve your code...

Consider chaining the response promises in a different way:

promises.push(promise.then(function(response) {
    return {
        response: response,
        additionalConfig: additionalConfig;
    };
}));

After that, you can utilize this sequence of actions:

return $q.all(promises).then(function(data) {
    angular.forEach(data, function(obj) {
        console.log('Response', obj.response);
        console.log('Additional config', obj.additionalConfig);
    });
});
