To setup the server you need to do the following : -
RUN command :- "npm install" this command will install modules required to run server.
have mongodb and mongo compass install in your system .
RUN command :-
"npm start"
this will start your server
Now open mongo compass you will find a database named "test123" and two collections named "tenantschema" and "userschema" , open collection and import the "tenantList.json" and "userList.json" file in "tenantschema" and "userschmema" respectively.
you have to restart the server now . So stop the server and start server again via "npm start"
NOTE :- you can change PORT number in env file a you can change database name via DATABASE_URL = "mongodb://localhost:27017/database_name" where database_name is your actual database name .
