Dynamicly change Language locale of an Date Format Angular EJ 2 Forums

Injecting strings that can change at runtime into translations is quite common, and works seamlessly with $localize. Our arcade cabinet images currently have English-only alt text that can serve to demonstrate. When a visitor hits our root route (/), we try to match one of our supported locales to one of their accepted locales, retrieved from Express’ helpful req.acceptsLanguages(). The function returns the locales in the incoming Accept-Language header as an array. Our new matchSupportedLocales() function uses this array, along with our supported locales and our default locale, to make the best match.

If you define it for your application, you have to add it into app.module.ts. But there is also another solution – you can have multiple bundles for each language, which probably will be better approach as app will be faster. But this solution is not applicable for every application and doesn’t answer the question. Also remember to process change detection in application by using tick() method in ApplicationRef. Calling tmhDynamicLocale.set will return a promise that will be resolved when the locale is loaded and will resolve to the new locale.

Which @angular/* package(s) are the source of the bug?

If you have a specific URL per locale and redirect the user when he changes locale, the first approach should work just fine. If you are already using ngx-translate, creating a localizedDate starts to make sense. With the localizedDate, we gain in maintainability in the syntaxe and by using a single internationalization library for dates and contents. As others, it has its cost, this approach adds extra computation in the app. Same as the previous approach, the static locale can be replaced by value resolved in a service. That way, we can dynamically change the locale without reloading the entire app.

We can use the innerHTML attribute with the translate pipe on any HTML element. This will allow ngx-translate to use the messageformat compiler for rendering the translated messages. Run the following command to create the nav-bar component for the application. Add the following lines of code in thesrc/app/app.module.tsfile to import the required modules. Run the following command to create a new module in your app.

Angular Dynamic Locale Examples and Templates

We can use this section to define our app’s supported locales. The first-party @angular/localize package is a robust i18n solution for our Angular apps. It is missing some features, however, like support for localized numeral systems. And, if you find Angular creating a production version of your app for each locale a little excessive, you might want to try some third-party Angular libraries for internationalization. Well-documented and fully featured via first-party plugins, Transloco is definitely worth a look.

You may have noticed that managing translation files with Angular’s localization library is a bit clunky. We have to copy the source locale for each of our other supported locales, and we have to keep all these files in sync as we make changes within our app. We have created a nav-bar that has a drop-down menu with two options for selecting the language of our app during runtime. We will also display the siteLanguage in the nav-bar so it gets updated as we change the language of our app.

Next, let’s run the extract-i18n CLI command from our project root to pull this marked string into a translation file.

After the https://forexhero.info/ is changed, the event ‘$localeChangeSuccess’ will be triggered. We will create an object of the Feedback class type, which will bind to the form. The saveFeedback function will be invoked as soon as the form submission is successfully submitted. The constructor is used to initialize the titleParam and the copyrightInfoParam properties. We will use both in the template file while fetching the translation values.

In this article, you learned how to use these packages to internationalize and localize AngularJS applications. In these cases and others, human translations may be required; however, that’s a topic for another blog post. One option is to use programmatic translation APIs, especially if the strings in your application are simple literals without variables or pluralized expressions.

The example above is an English translation, of course, so we provide the language’s two plural forms, one and other. TodoCount is an interpolated integer counter that determines which form is rendered at runtime. We can inject the value of todoCount into our plural form messages using Angular’s usual syntax. Of course, the implementation details will depend both on your production server and the needs of your app.

It is very important that you follow this convention when you define your locale, because the Angular i18n tools use this locale id to find the correct corresponding locale data. Internationalization is the process of designing and preparing your app to be usable in different languages. Localization is the process of translating your internationalized app into specific languages for particular locales. For changes made to appLocaleService to be reflected in our app, we need to reload the Angular app. Reloading the app may reset the app state and re-trigger HTTP requests. With the static string value fr-FR, the LOCALE_ID value can not be dynamically changed.

Ahmed Ghoul wrote a super article about Pure vs Impure Pipe in Angular. Pure pipes (like the built-in date pipe) are called only if the pipe’s inputs changed. On the other hand, impure pipes are called on every change detection cycle. The title key will accept a parameter called “company”, which will help us add the value dynamically. The copyright key will accept currentYear and “company” as the parameter.

Angular Dynamic Locale

I changed the sourceLocale to Canadian English (en-CA) above and added Arabic as a supported locale. We need to include the path to a translation file for each locale other than the source . Locale rules are shipped with the angular-i18n package, so all you have to do is make the package contents available to your application as needed. But how do you generate the JSON files for your translation tables? There isn’t exactly a package you could download and plug into our application.

angular dynamic locales a plethora of libraries and frameworks both client- and server-side. 🗒 Note » It’s probably a good idea to go to Project Settings ➞ Placeholders and selecting the OASIS XLIFF placeholders to match the placeholders Angular uses in our translation files. This will make the placeholders easy to spot and use for our translators. Similar to numbers, the simplest way to localize a date is to use the date pipe in our component templates. 🔗 Resource » The CLDR Language Plural Rules document lists plural forms for all languages.

From the project root, let’s run the following from the command line. Angular-translate, angular-dynamic-locale, and gulp are powerful tools for internationalizing an AngularJS application that encapsulate painful low-level implementation details. Unlike i18n data, locale rules are global to the application, requiring the rules for a given locale to be loaded all at once.

For a demo app that illustrates the ideas discussed in this post, check out this GitHub repository. Pluralization is a pretty hard topic when it comes to i18n and l10n. Different languages and cultures have different rules for how a language handles pluralization in various situations. Note that the name of the module is different from the name of the package.

You can add a description of the text message as the value of the i18n attribute, as shown in the example below:

Be it web or mobile apps, Phrase enables you to translate any kind of software. We will use the dropdown module of ngx-bootstrap to display a language selection dropdown in the navbar of our app. For the creation of the feedback form, we will use template-driven forms. That is why we import the FormsModule as well as the custom NgxTranslateModule.

If a visitor to our app has ar-SA in his accepted locales, we will serve the ar version of our site. Of course, you’re here for Angular internationalization , and we’ve got you covered. It’s no surprise that Angular has robust built-in i18n support.

Angular support for i18next comes in via the third-party angular-i18next package. At this point, our English source translations are available in our Phrase project. Our translators can add Arabic as a project language, then use the Phrase web console to get their translation work done. Angular pulls the ICU nested expression bit out into its own separate .

In the example below the custom id myId is used for two different messages:

The get() function of TranslateService is used to fetch the translated value of a key in a TypeScript file. The ngx-translate library has a wide range of APIs, which allows us to manipulate the translation data during runtime. No matter which i18n library you choose to go with, Phrase can take your localization process to the next level.

🔗 Resource » Get the entire code of our fully localized app from GitHub. 🤿 Go deeper » Check out of all the formatting options for the date pipe, as well as its function equivalent, formatDate(). Angular implements the ICU standard for its localized plurals. ICU is a bit outside the scope of this guide, but you can read more about it in The Missing Guide to the ICU Message Format.

Each of our configured locales will generate a unique copy of our app with that locale baked in. Take a look under the dist directory and you should see something like the following. 🗒 Note » In our actual code on GitHub we’re using a little injected service to provide the cabinet data.
