I'm building SaaS and documenting the process. Day 11: experimenting with subdomains

This is the eleventh episode in the reality show about the development SaaS app from scratch. The previous episodes:

Day 7: board settings page
Day 8: board settings page, more details and tabs
Day 9: board settings page, more tabs
Day 10: finished all 4 meta lists for board settings page

There is actually not much to tell about because I was experimenting with subdomains setup. I tried to understand how it can be established in different environments: development and production. They work differently. For the development, I found there is no need to edit the /hosts file and working with subdomains can be organized much easier (just with temporary variables).

As for production, it may be tricky, but doable (did it in the past).

Time spent: 3 hours
