Multilingual Application In Angular

What is Multilingual 

In software development, multilingual support refers to the capability of an application to display its content and interface in different languages based on the user's preference. This can be achieved by implementing localization techniques, where texts, dates, currencies, and other culture-specific data are stored in separate language files and loaded dynamically based on the user's selection. By using multilingual support, you can provide a better user experience to a global audience and increase the application's reach and appeal.

Advantage

1. Increased market reach: By supporting multiple languages, you can expand your user base to new regions and countries where people may not speak the original language of the application.
2. Improved user experience: Users feel more comfortable and confident using an application in their own language, leading to a better overall experience.
3. Increased credibility: Showing support for multiple languages can demonstrate a commitment to diversity and inclusiveness, which can positively impact the reputation of your application.
4. Better communication: Multilingual support can help break down language barriers and facilitate communication with users from different backgrounds.
5. Increased customer satisfaction: By providing a localized experience, you can increase customer satisfaction and loyalty.

Overall, multilingual support is an important aspect of modern software development that can bring numerous benefits to your application and users.

What Multilingual Can Do?

1. Display text in different languages
   The application can dynamically switch between languages based on the user's preference, displaying all the text in the selected language.
    
2. Support for different character sets
   Different languages may have different character sets, and multilingual support ensures that the application can display and process characters from any language.
    
3. Localized formatting
   Multilingual support can also include localized formatting for things like dates, times, currencies, and numbers, ensuring that the user sees the information in a format that is familiar and meaningful to them.
    
4. Keyboard and input support
   Multilingual support can also include support for different keyboard layouts and input methods, allowing users to input text in their preferred language.
    
5. Multilingual content
   Multilingual support can also include the ability to store and manage multilingual content, such as product descriptions, support articles, and other information, in multiple languages.

Example of Multilingual

Here is an example of a multilingual file in JSON format that can be used for localization in a software application,

{
    "en": {
        "home": {
            "title": "Welcome to our Homepage",
            "description": "Explore our products and services"
        },
        "products": {
            "title": "Our Products",
            "description": "Discover our range of products"
        },
        "contact": {
            "title": "Contact Us",
            "description": "Get in touch with us"
        }
    },
    "fr": {
        "home": {
            "title": "Bienvenue sur notre page d'accueil",
            "description": "Explorer nos produits et services"
        },
        "products": {
            "title": "Nos produits",
            "description": "Découvrez notre gamme de produits"
        },
        "contact": {
            "title": "Contactez-nous",
            "description": "Entrez en contact avec nous"
        }
    }
}

This file contains the translation for different text elements in the application, such as page titles and descriptions. The file uses the JSON (JavaScript Object Notation) format, which is a widely used data interchange format that is easy to parse and generate.

In this example, the file contains translations for English (en) and French (fr) languages. When the user selects a language, the appropriate language data can be loaded, and the text elements in the application can be displayed in the selected language.

As with the previous example, this is a basic example, and the actual implementation can be more complex, depending on the size and complexity of the application. The key idea is to store the language-specific data in separate files and dynamically load the appropriate data based on the user's language preference.

How to Access JSON Multilingual File in C# WebAPI

Load the JSON file into a string variable: You can read the file using the File.ReadAllText method and store the contents in a string variable.

string jsonText = File.ReadAllText("path/to/multilingual.json");
multilingual.json -- Customer specific name u can use

eg

string jsonText = File.ReadAllText("path/to/Client1.json");
string jsonText = File.ReadAllText("path/to/Client2.json");
string jsonText = File.ReadAllText("path/to/Client3.json");

and this client name also you can directly access from the tenant table while login

eg : 

string resourcename= context.Tenants.Where(a => a.IsActive == true&& a.TenantID==userDetail.tenantid).Select(i => i.resourcename).FirstOrDefault();
var json = File.ReadAllText(HttpContext.Current.Server.MapPath("~/language/"+ resourcename + ".json"));
Object language= JsonConvert.DeserializeObject(json);

How to Access a file In Angular Front End

$scope.productviewlabel = $scope.UserInfo.data.language.productview;
