When it comes to localization in web applications, the ability to support multiple languages and adapt to regional preferences is crucial. Let's compare Express.js, PHP Laravel, and Total.js in terms of their localization capabilities:
This blog post provides a general overview of the frameworks and their characteristics, but it is important to conduct thorough research and analysis before making any decisions regarding the selection of a framework for your specific project. The opinions expressed in this blog post are those of the author and should not be considered as professional advice or the sole basis for making decisions. It is recommended to consult with experts and refer to the official documentation and community forums of each framework for the most up-to-date and accurate information.
Express.js is a minimalist web application framework for Node.js. While it does not provide built-in localization features, it offers a flexible environment to implement localization in your application. Express.js can be combined with various libraries and tools to achieve localization functionality, such as i18n, i18next, or custom middleware.
Let's assume you have an Express.js application for a user CRUD (Create, Read, Update, Delete) app, and you want to demonstrate localization for the views. Here's an example of how you can implement localization in Express.js:
Inside the "locales" folder, create language-specific JSON files for each supported language. For example, create
en.json for English and
fr.json for French. These files will contain key-value pairs for translated strings.
app.js or main application file:
index.ejs file inside the "views" folder with the following content:
Now, when you access
http://localhost:3000 in your browser, the view will display the localized strings based on the selected language. You can switch between languages by setting the
lang cookie with the desired language code ('en' for English or 'fr' for French).
This example demonstrates a basic implementation of localization in an Express.js view for a user CRUD app. You can extend this approach to other views and routes in your application and add more language files to support additional languages.
Laravel is a popular PHP framework that offers comprehensive localization support out of the box. It provides features like translation files, localization helpers, and automatic language detection. Laravel's localization capabilities are based on the industry-standard Gettext framework and provide a smooth and efficient way to handle translations.
Here's an example of how you can implement localization in Laravel for a user CRUD app:
config/app.php file and ensure that the
locale parameter is set to the default language you want to use. For example:
Laravel uses language files to store translations. Inside the
resources/lang directory, create a folder for each language you want to support (e.g.,
en for English and
fr for French). Inside each language folder, create a file called
Open your user CRUD view file (e.g.,
resources/views/users/index.blade.php) and use the
trans() helper function to display the translated strings.
To allow users to switch languages, you can add language selection links or a dropdown menu to your view. For example, you can create a language selector dropdown menu that sends a POST request to a route like
/language to update the language:
web.php routes file, add a route to handle the language switching request:
Run the following command in your project directory:
Now, when you access your user CRUD app view, the strings will be displayed in the selected language. By changing the language selection, the view will update accordingly.
This example demonstrates a basic implementation of localization in Laravel for a user CRUD app view. You can expand on this by applying localization to other views, adding more languages, and using more advanced features provided by Laravel's localization system.
.html files and
@(Text to translate) markup
To initialize localization, you need to register a localization delegate that obtains language from the request.
controller.language = 'en'
First, install Total.js as a global module via
$ npm install -g total4 because NPM registers Total.js command-line tools and terminal helpers.
Open terminal and write:
Total.js finds all texts for translation and creates a resource file translate.resource for translation. The keys in the resource file are hashes due to performance and memory consumption. Copy the file: /resources/fr.resource and translate it to e.g.:
Run the app
$ node index.js and visit:
Let us create project and install Total.js
The localization can be declared in definition file
Don't forget to first install Total.js as a global module
$ npm install -g total4 because NPM registers Total.js terminal / command-line helpers.
Creating of resource file
Open terminal and write:
Output will be:
The content of that
/translate.resource can be translated into any language you want.
/translate.resource file into
Example for French language:
/resources/fr.resource and make necessary translations.
In summary, while Express.js provides flexibility for implementing localization using various libraries, Laravel stands out with its comprehensive built-in localization support. Total.js clearly has the most advanced, complete and fast localization mechanism as it can even support writing translation string anywhere in sources code, this way, even Rest APIs, errors outputs can be localized without any problem. But alfter all, consider your project's specific requirements, development stack, and the level of localization support you need when choosing a framework for your localization needs.
