Is it installed or being tested on localhost?

Web App and the Telegram Mini App are designed to operate in an online environment and cannot function properly in an offline or local setup. Both the Web App and Telegram App are dependent on external services and servers to handle real-time interactions, data synchronization, and various API calls, which require a live internet connection. So your answer is:

No, the application is neither installed nor being tested on localhost!

When running on localhost, many critical features of the platform may fail to work, as these require access to live databases, external APIs, or Telegram’s cloud infrastructure. Additionally, the Telegram Mini Game, specifically, is built to interact with the Telegram bot API, which mandates an active internet connection to function. Since Telegram’s bot services operate over the internet, local or offline testing cannot replicate this environment effectively.

Therefore, for proper installation, testing, and operation, both the Web App and Telegram Mini App must be deployed on a live server with internet access to ensure that all features, including real-time updates, API interactions, and user engagements, work as intended.

In summary, testing and full functionality of both platforms are only achievable in a live, online environment. Using localhost or offline setups would severely limit the app’s capabilities and could lead to incomplete or incorrect testing results.
