Multi-language Supported React Native App Development

Internationalization is essential for crossing the language barrier among software program users. Not every app necessitates taking into account a worldwide audience. However, internationalization will be necessary for your React Native app development project if you want your app to be available to customers in other countries.

 

The scenario is no different when it comes to a mobile app. As your app’s user base grows across several nations, it’s critical to give users the option of using the app in their local language. Multilingual applications may be used in more than one language. As noted below, we can update the language in a few instances.

 

• You can select the language you want to use throughout the registration process.
• On the common header, you can change languages at any moment.
• Click the “User Preferences” section to change your language.

 

Importance of Developing Multilingual Business Apps

• Multilingual support can help you improve your company’s image and familiarity.

 

• Increase your global Search Engine Results Page (SERP) ranking. SERPs will rank you higher since you can provide material that appeals to a larger audience.

 

• You may reach a larger audience through a multilingual React Native app development. It allows people all around the world to easily access and comprehend your products and services.

 

• Reduce your drop rate by making it simple for users who do not speak or comprehend your language to alter the language of the app’s content.

 

Now that you are a little aware, let us get into knowing how to go about multi-language supported React Native app development.

 

Approaches For Multilingual React Native App Development

Yarn is popular among developers because it is quicker and provides additional features such as Workspace. It is quicker because it caches your packages, which speeds up the process. This package manager also optimizes the resources by parallelizing operations, which speeds up the installation process.

 

In this section, we will utilize Yarn package management for simplicity and speed.

 

1. Begin by adding the i18next and react-i18next Yarn packages to your project:

 

yarn add i18next

yarn add react-i18next

 

After these scripts have been completed properly, open the package. To confirm that the libraries have been added to the dependencies section, use JSON.

 

1. After you have added your packages, navigate to App.js. App.js, our principal wrapper component, should include every package or module necessary in a multilingual React Native app development. App.js is a JavaScript framework that allows developers to construct native-like mobile applications. This, however, does not affect the program’s performance.

 

• On iOS and Android, native transitions are possible. 
• Allows you to personalize the appearance and feel by using custom themes and widgets.
• Views and pages are simple to navigate.

 

As a result, we will locate the code that corresponds to our full mobile app in App.js. We must include our above packages in app.js because they are available throughout our application. Here are the packages to be imported,

 

import { I18NextProvider } from ‘react-i18next’;

import i18next from ‘i18next’;

 

1. Create a translation folder under src after importing your libraries into app.js. Make two more folders: 

 

• en (for English) 
• de (for German)

 

Following that, include two JSON files, which we’ll refer to as common.json. However, based on the requirements of your project, you can name these files whatever you choose. Each language should have its common.json file. Language-specific strings for our two languages, English and German, are included in these two files.

 

1. When you’ve finished creating your language and multilingual support resource files, import them into app.js. You may accomplish it by using the import function, as seen below:

 

import common-en from ‘./translation/en/common.json’;

import common-de from ‘./translation/de/common.json’;

 

1. Once you have completed the preceding steps, create a function in app.js. This function configures the language you have selected. As is traditional, we’re using the same resource files that we added to app.js in Step 4 in this code. JSON is an example of a data format. 

 

Furthermore, the lng variable is linked to a state variable, which represents the language of your multilingual app, in this example en and de. As a result, the idea is that depending on the circumstance, the language of the entire program changes. If the state has code en, the language will change to English. If the state has code de, the language will change to German.

 

1. When the app.js file is loaded for the first time with the default language, the preceding function is run. ComponentDIdMount or Constructor are good names for this procedure.

 

1. The state variable is set to the language variable. The value of this state variable can be altered based on the language used.

 

1. Now, you need to make some adjustments to the render method in app.js. Encapsulate and add the main component before wrapping it with i18nextProvider. To retrieve translation properties for our nested components, we utilize i18nextProvider.

 

1. After we have completed all of the above stages, we are free to use the translated text anywhere we choose. The following is how it works:

 

• To begin, we will destructure our variable from screenProps, which in our instance is t.
• The variable you have selected, say t, will then be used to pass the key. The variable we are using to provide the key is common. The screen text is empty.
• When you launch the app, the text should appear in the language that was chosen as the app’s default.js.

 

1.  Finally, we must specify where we want the language selection option to appear. Including two flags, for example, in the Settings, Profile header, or drop-down menu.

 

Wrapping Up

There are several ways to enable translation help in your app. This is only one of several classes offered. To opt for a multilingual React Native app development, follow the steps indicated above. You can easily create a large number of files for various languages and import them for translation in the same way that we did for English and German.

 

The usefulness of software capable of switching languages and adapting to the target system is enhanced in the modern world. This sort of application will be ranked higher in app stores and will receive more attention from mobile users than fixed-language software.
