[FEATURE] Implement Multilingual Support for finNews Web Application

[IkkiOcean]

Description:

To enhance user experience and reach a wider audience, we need to add multilingual support to the finNews web application. Users will be able to select their preferred language, ensuring that all financial news, articles, and interface elements are accessible in their chosen language. This will help make the platform more inclusive for non-English-speaking users and those who prefer consuming content in their native language.

Use Case:

A user from a non-English speaking country visits finNews to stay updated with the latest financial news. Upon landing on the page, they notice an option to select their preferred language (e.g., Spanish, French, Hindi, etc.). They select their language, and all the content (headlines, news articles, user interface text) switches seamlessly to the chosen language. This allows them to comfortably navigate the site and understand the news without language barriers, thus improving their overall experience and engagement with the platform.

What I will do:

1. Language Selection Feature:
   • Add a language selection option, either in the header or footer of the web application.
   • The language selection UI should be intuitive and clearly visible to the user.
2. Translation Scope:
   • Translate all user-facing content, including:
   • Financial news headlines and articles.
   • UI elements like navigation bars, buttons, menus, tooltips, etc.
   • Error messages, notifications, and form labels.
3. Translation Management:
   • Languages to support initially:
   • English (default)
   • Spanish
   • French
   • German
   • Hindi
4. Real-Time Language Switching:
   • Ensure that when users switch languages, the changes take effect immediately without reloading the page.
   • Store the selected language in local storage or user preferences, so users do not have to reselect their preferred language on future visits.
5. Fallback Language:
   • Implement a fallback mechanism (e.g., defaulting to English) if a translation is missing for any content.
