Thank you for your reply sir. I don't have any index.html file sir. Because I am using
Nx and Angular CLI(https://nx.dev/angular). Multiple
application developed here. If once build application, i got index.html
except api.
While build api (ng serve api --prod) I got 2 files only (main.js and main.js.map).
I have 3 application in NX angular structure.
1. Student
2. Teacher
3. Api - ( This for mock api )
I have successfully deployed 1 and 2 in production. But I couldn't deploy API. I want to deploy api (mock api) for mobile development service.
