How to configure & run multiple websites with respective databases with single Laravel code instance

I have a scenario that I want to implement in Laravel.

I have already implemented this kind of approach in custom PHP. But this time, I want to shift all websites to a framework (Laravel).

I have multiple domains for different regions implemented (Localization), each domain has its own database and all database tables structure are same only the data is different.

Now I want to use single Laravel code instance with the ability to connect multiple databases with multiple domains and each domain has its own theme files.

Let suppose: I have some domains

 1. abc.com and it has database with name of db_abc with theme/template ABC
 2. xyz.com and it has database with name of db_xyz with theme/template XYZ

When abc.com domain is hit/accessed, I want to connect with DB db_abc and load data in ABC theme/template. Similar when xyz.com is hit/accessed the database connection should be made with db_xyz and data should be loaded into theme/template XYZ files.

Please help me in this regard.

Thank you.
