Translations for Angular JS

Often it is because Angular had a breaking changes. If it’s not an option for you, then check the changelog to know which version is the last compatible version for you. The Angular Translate filter is not required, since $translate.instant() offers the same as a service. Beside this, please pay attention to Pascal’s answer. Translate.use(‘en’) tells the service which is the current language to use for translations.

With Translate for Angular JS, users are able to create beautiful, dynamic, multilingual websites. Integrating Translate.com with Angular JS allows businesses, individuals, or eCommerce websites to successfully reach and engage with global web users. Integrate Translate.com today to upload content for your localized website, including photos, videos, copy, meta tags and more.

Angular-translate is a JavaScript translation library for AngularJS 1.x app. I’d say using a $scope.$watch is rather overkill since Angular Translate is offering a Service to be used in the controllers. Since @PascalPrecht is the creator of this awesome library, I’d recommend going with his advise and use the provided directive which seems to handle translations very intelligent. This is my preferred way since I don’t have to handle promises this way.

This method allows you to configure the TranslateModule by specifying a loader, a parser and/or a missing translations handler. Since lazy loaded modules use a different injector from the rest of your application, you can configure them separately with a different loader/compiler/parser/missing translations handler. You can add translations manually using setTranslation but it is better to use a loader.

‘Fname’ | translate

You see, with , Angular will watch the expression; when the localization data is loaded, the value of the expression changes and the screen is updated. The reason for that is, that in angular-translate’s events are $emited on $rootScope rather than $broadcasted on $scope because we don’t need to broadcast through the entire scope hierarchy. The directive takes care of asynchronous execution and is also clever enough to unwatch translation ids on the scope if the translation has no dynamic values. Remember, we told the service to use en as the current lang, so all translation results will come from en.json initially.

Even if you can successfully debug this issue, the bigger problem is that the development work involved is huge. A developer has to manually extract every string on the site, put it in a .json file, manually reference it by string code (ie ‘pageTitle’ in this case). Most commercial sites have thousands of strings for which this needs to happen. The forRoot static method is a convention that provides and configures services at the same time. Make sure you only call this method in the root module of your application, most of the time called AppModule.

The following translations should be stored in en.json. If you are still having difficulty after looking over your configuration carefully, please post a question to StackOverflow with a specific tag. Especially if the question are related to AngularJS or even JavaScript/browser basic technologies (maybe your issue is not related to angular-translate after all). Of course, you could encapsulate the $translateservice in a method and call it in the controller and in the $translateChangeSucesslistener. If the translation file isn’t finished loading at the time you use this method, you won’t get a translation at all. This tutorial was verified with Node v16.4.0, npm v7.19.0, @angular/core v12.1.0, @ngx-translate/core v13.0.0, and @ngx-translate/http-loader v6.0.0.

• I’d say using a $scope.$watch is rather overkill since Angular Translate is offering a Service to be used in the controllers.
• Personally I would even recommend not loading translations dynamically if you don’t have to.
• You can setup a provider for the MissingTranslationHandler in the bootstrap of your application , or in the providers property of a component.
• If you don’t know in-context editing yet, have a look at our demo.

At some point, your web application may require serving a multilingual user base. Internationalization, or i18n for short, is the process by which you make your app usable for those with a different native language. It extends the methods provided by angular-translate and makes every translatable string editable by the Phrase in-context editor. Adding in-context editing capability to your localized AngularJS app is easy with the angular-phrase adapter. If you’re familiar with the Phrase in-context editor you know what a powerful tool it is to speed up the translation process and boost the content’s quality. Editing translations directly on the page is fast and easy!

@PascalPrecht Just a question, is it a good practice to use bind-once with translation? DigitalOcean makes it simple to launch in the cloud and scale up as you grow – whether you’re running one virtual machine or ten thousand. This textbox defaults to using Markdown to format your answer.

You can change the default path and file extension by providing extra parameters to the new TranslateHttpLoader() constructor. In this article, you will use ngx-translate in an Angular application. If you use a SharedModule that you import in multiple other feature modules, you can export the TranslateModule to make sure you don’t have to import it in every module. Whenever i click on Registration tab corresponding Registration.html file in ng-view.

Actually, you should use the https://forexhero.info/ directive for such stuff instead. On the initial page load, the translation key is shown instead of the translation for that key. Connect and share knowledge within a single location that is structured and easy to search. In this article, you used ngx-translate in an Angular application. You can also place a directive on any HTML element to get translations. The value may also be another object, which allows you to group your translations however you would like.

You can use useDefaultLang to decide whether default language string should be used when there is a missing translation in current language. If you set it to false, MissingTranslationHandler will be used instead of the default language string. Using a compiler opens the door for powerful pre-processing of translation values. As long as the compiler outputs a compatible interpolation string or an interpolation function, arbitrary input syntax can be supported.

In the text of your translation value, you can also include double curly braces around a variable name, which will later allow you to interpolate strings dynamically into your translations. You will need to implement the TranslateLoader interface and provide it in your module like above. This will provide access to the core of the translate service, pipe, and directives. To develop this app, we have used HTML, CSS, translate.js and AngularJS.

Once you’ve angularjs translated your loader, you can provide it in your configuration by adding it to its providers property. You can either use the TranslateService, the TranslatePipe or the TranslateDirective to get your translation values. When you lazy load a module, you should use the forChild static method to import the TranslateModule. Finally, you can use ngx-translate in your Angular project. You have to import TranslateModule.forRoot() in the root NgModule of your application. I am not able to translate Fname in the above code.

• AngularJS is an awesome Javascript framework to build single-page applications with Javascript.
• This returns an Observable, and as such, is asynchronous, which guarantees that the translation file will be loaded before using the value.
• Some familiarity with setting up an Angular project.
• Connect and share knowledge within a single location that is structured and easy to search.

This returns an Observable, and as such, is asynchronous, which guarantees that the translation file will be loaded before using the value. This Observable then completes as soon as the value is retrieved. Localizing your existing AngularJS apps with angular-translate can be done easily. It’s a great module that covers everything you need to implement a localized version of your apps. When developing large AngularJS applications for a wide audience, internationalization of these apps becomes more and more important to make the user interface accessible for users worldwide. Once you’ve imported the TranslateModule, you can put your translations in a json file that will be imported with the TranslateHttpLoader.
