Loader for AngularJS Static File Translation

Just dipping my toes into the world of Angular and feeling a bit overwhelmed by this code. Can someone lend a hand? I'm trying to figure out how to tweak it to use my en_US.json file located at locale/locale-en_US.json.

 .factory("$translateStaticFilesLoader", ["$q", "$http",
    function(a, b) {
        return function(c) {
            if (!c || !angular.isString(c.prefix) || !angular.isString(c.suffix)) throw new Error("Couldn't load static files, no prefix or suffix specified!");
            var d = a.defer();
            return b({
                url: [c.prefix, c.key, c.suffix].join("../locale/locale-"),
                method: "GET",
                params: ".json"
            }).success(function(a) {
                d.resolve(a)
            }).error(function() {
                d.reject(c.key)
            }), d.promise
        }
         $translateProvider.preferredLanguage('en_US');
    }
]);

Answer №1

I'm feeling a bit foolish. I finally figured out how to solve my coding issue, and the solution was as simple as:

app.js(main)

app.config(['$translateProvider', function ($translateProvider) {
    $translateProvider.preferredLanguage('en_US');

    $translateProvider.useStaticFilesLoader({
      prefix: '../locale/locale-',
      suffix: '.json'
    });
}]);

services.js

app.factory("$translateStaticFilesLoader", ["$q", "$http",
function(a, b) {
    return function(c) {
        if (!c || !angular.isString(c.prefix) || !angular.isString(c.suffix)) throw new Error("Couldn't load static files, no prefix or suffix specified!");
        var d = a.defer();
        return b({
            url: [c.prefix, c.key, c.suffix].join(""),
            method: "GET",
            params: ""
        }).success(function(a) {
            d.resolve(a);
        }).error(function() {
            d.reject(c.key);
        }), d.promise;
    }
    $translateProvider.preferredLanguage('');
}]);

All I had to do was copy the static translate from the original source and paste it into my services file, leaving all the parameters empty.

To include static files in your project using the $translate module, you will need to load an external *.js file that contains the $translateStaticFilesLoader factory discussed earlier.

Instead of manually adding the factory code like @ALoppu, a more efficient method is to load the external script immediately after including angular-translate.js:

<script src="vendor/angular/angular-translate.min.js"></script>
<script src="vendor/angular/angular-translate-loader-static-files.min.js"></script>

For the most up-to-date version of

angular-translate-loader-static-files.min.js
, visit GitHub here.
